EXAIR Industrial Dry Vacuums, A Solution For Every Application!

It seems we have broken out of this deep freeze here in Cincinnati and spring has taken hold. Spring cleaning is also taking hold. That means it’s time to start looking for ways to make that chore as easy and hassle-free as possible! If you’re like me and enjoy spring cleaning the EXAIR dry vac products are right for you!

EXAIR has three dry vacuum systems, and they each have a application that fits their performance and abilities.

The first is our Chip Vac System

EXAIR’s Chip Vac Family

The Chip Vac is designed specifically for vacuuming chips. It creates a powerful direct flow that is ideal for metal, wood, and plastic chips.  Because it has a filter bag, in can also handle the occasional dusty material, and keep the surrounding air clean.

If the operation machines different materials, the lid can be removed from one drum and moved to another, to keep the materials separate for easy recycling.

The 30, 55 & 110 Gallon Chip Vac’s consume 40 SCFM @ 80 PSI while the 5 Gallon size consumes 33 SCFM @ 80 psig.  All 4 models are rated at a super quiet 77 dBA!

The second is our Heavy Duty Dry Vac

HDDV
EXAIR Heavy Duty Dry Vac Family

The Heavy Duty Dry Vac was engineered to vacuum more dry material in less time with less wear. The hardened alloy construction resists premature wear and the increased power makes difficult jobs and harsh environments more easily handled.

The Heavy Duty Dry Vac is ideal for abrasive materials such as steel shot, garnet, metal chips and sand, and is also useful for general purpose applications such as vacuuming floors, machines, work stations and machinery/equipment.

Like the Chip Vac, the Heavy Duty Dry Vac drum lid fits any open top drum, and can be moved from one drum to another facilitating recycling efforts.

The 30, 55 & 110 Gallon Heavy Duty Dry Vac’s consume 68 SCFM @ 80 PSI and have a sound level of 82 dBA.

Below shows the powerful performance of the Heavy Duty Dry Vac vs the Standard Chip Vac when considering large, heavy material and the increased performance you could expect.

The HEPA Vac (High Efficiency Particulate Air) has the added benefit of the HEPA quality filter system.  Filtration per IEST-RP-CC-007 to 99.97% minimum filtration at the 0.3 micron level ensures performance meets the needed criteria. Like the Chip Vac and the Heavy Duty Dry Vac it will attach to ordinary open top drums as well.

The EXAIR Chip Trapper™ System Extends Machine Coolant Life

Have you realized that you spend too much time cleaning out your CNC machine?  Do you find that It is messy and backbreaking work?  Do you spend too much money replacing the coolant in your system?  If you answer yes to any of these, EXAIR has a product for you; the Chip Trapper System.

EXAIR created this product to reduce the down time and extend the life of your coolant.  This device will save you money and time with productivity, coolant, and repairs.  In this blog, I will go over some of the features and benefits with the Chip Trapper Systems.

EXAIR offers two types, the Chip Trapper and the High Lift Chip Trapper.  They are designed to move fluid into the drum to be filtered, and to allow the clean fluid to be placed back into the sump.  The Chip Trapper works great for quick coolant cleaning at the floor level.  The High Lift Chip Trapper is ideal for cleaning viscous fluids as well as for reservoirs below the floor level.

Both types use a pneumatic two-way pump to move the fluid.  They come in three different drum sizes, 30 Gallon (114L), 55 Gallon (208L), and 110 Gallon (418L). So, you can clean large sump tanks with only one cycle through the cleaning system.  They come standard with a 5-micron bag filter that can hold over 5 gallons of material.

EXAIR can also offer filter bags in 5 other micron ranges from 1 micron up to 200 micron.  And if you are not sure on the other filtration ranges, EXAIR offers a filter sample pack, model 901060-SP, that includes one of each type.

Chip Trapper Cut Away

The Chip Trapper System includes the drum, the two-way pneumatic pump, a drum dolly, a directional flow valve, 10 feet (3m) of vacuum hose, 20 feet (6m) of compressed air hose, a chip wand, a shut off valve, and two additional filter bags.  All you need to do is to attach the Chip Trapper System to a filtered compressed air source.

The High Lift Chip Trapper offers a more powerful pneumatic pump which can fill a 55 gallon (208L) drum in 85 second from 15 feet (4.5m) below.  And, instead of the 10 feet (3m) vacuum hose, it will come with a  20 feet (6m) vacuum hose.

The unique features with the Chip trappers are the abilities to clean the CNC sump very quickly and with less mess.  Also, by using compressed air to pump the coolant in and out of the drum, it will aerate the coolant.  This will reduce bacteria growth and extend the life of the coolant. Thus, saving you money with those more expensive coolants.

Another benefit is that the pneumatic pump does not have any moving parts to wear out.  So, it will last you a long time without worrying about motor failures or loud noises.

You can watch the video of the operation here:

A list of some benefits that you will see if you purchase the Chip Trapper System is as follows:

  • The number of complete coolant change-outs are reduced.
  • The speed to get the CNC machines back operational to make parts.
  • Reduce the number of barrels of coolant concentrate per year.
  • Bacterial growth dramatically reduced as the Chip Trapper aerates the coolant.
  • Filter bags will remove the chip fines and some tramp oils keeping the coolant fresh.
  • Quiet and long lasting
  • A complete system that is easy to use.

As an added note, some CNC machines come with a spindle coolant feature.  This new technology helps in the need to increase speeds and feed rates.  The coolant is pumped to the top of the machine and fed directly through the spindle.  This type of spindle uses a rotary union which allows the coolant to the spindle as it spins at a high rate of speed.  The rotary unions are very expensive and costly to replace.

These spindles are very susceptible to dirty coolant.  If a seal within the rotary union begins to leak inside the machine, you will not be able to diagnose the problem until they have a machine failure.  The Chip Trapper with help eliminate this chance and keep your machine from an extreme expensive breakdown.

When your machine is not operating, your productivity is lost.  The EXAIR Chip Trapper Systems can be that product for you to get you back up and running is a short period of time, extend your coolant life, and keep the area clean and safe.  A win-win proposition in saving money and time.

For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try.  And, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Chip Trapper or High Lift Chip Trapper.

EXAIR Reversible Drum Vac Fills A 55 Gallon Drum in 90 Seconds Flat, And Empties It Just As Fast

There are a few ways to get the liquid out of a drum:

  • You can use a pump.  Some pumps are even made to mount straight onto the lid of the drum.
  • You can siphon the liquid out, if you can get the drum higher than where you want to put the liquid.  And if you have the time.
  • You can turn the drum over.  I used to do field service in chemical plants…some of them had drum handlers on fork trucks that could pick up and tilt the drum to pour the liquid out.  Some of them pushed the drum over and simply let the liquid spill into a pit or below-grade sump.

But pumps break down.  Siphoning is finicky and slow.  I’m loath to knock the skills of the fork truck operator that can pour out a drum like a sommelier pours a fine wine.  And I’ll never forget the first time I saw an operator half-roll/half-dance a drum to the edge of that pit and let the liquid dump as he dropped it precisely where he wanted it…however, even in the context of the inner recesses of a chemical plant, it was simple, but inelegant.

EXAIR has an engineered solution that preserves the simplicity, though: the Reversible Drum Vac.  Thread the standpipe into the bung connection and the RDV itself into the vent, and that drum is now a two-way pumping system, able to be emptied via a 10 foot long Vacuum Hose in as little as a minute and a half.  Turn the knob on the RDV to switch modes, and you can fill that same drum just as fast.

With a simple turn of the knob, the Reversible Drum Vac can fill or empty a 55 gallon drum in 90 seconds!

 

 

 

 

 

 

The EXAIR Reversible Drum Vac Systems come with a variety of configurations and options:

  • Made to fit an existing 30, 55, or 110 closed top steel drum in good condition.
  • Mini Reversible Drum Vac System comes with a 5 gallon drum.
  • Deluxe Systems add a Drum Dolly and a set of tools.
  • Premium Systems add a drum (30, 55, or 110 gallon,) an upgrade to Heavy Duty Aluminum Tools, and a 20ft compressed air supply hose with shutoff valve and pressure gauge.
  • High Lift Reversible Drum Vacs generate a suction head of 180″H2O for maximum lift.  They’re also specified for higher viscosity liquids.

Below is a great video that showcases just how easy it is to from installing the Reversible Drum Vac to using the Reversible Drum Vac and just how fast the RDV operates.

If you’re looking for a fluid handling solution for liquids in drums, give me a call and we’ll talk about which Reversible Drum Vac System is right for you.

EXAIR Heavy Duty HEPA Vac™ for Dusty, Abrasive or Heavy Materials

Heavy Duty HEPA Vac Family

 

When it comes to industrial vacuums, wouldn’t it be nice to have a durable, long lasting vacuum that is quiet?  There is such a vacuum that has these qualities; the EXAIR Heavy Duty HEPA Vac System.  This vacuum system has no moving parts, no motors to fail, or bearings to wear.  They only require compressed air to operate.

The Heavy Duty HEPA Vac is used to vacuum dusty materials, solid materials, sand, and even heavier materials like steel shot.  The vacuum generator is made from a hardened alloy construction to resist wear and abrasion, and it is designed to create a powerful vacuum level measuring -60” H2O (-15 KPa) at 80 PSIG (5.5 Bar).  To accommodate the multiple types of industrial applications, EXAIR offers the Heavy Duty HEPA Vac Systems in three different options and in three different drum sizes.

The design of the Heavy Duty HEPA Vac is based on, like the name states, the HEPA filter.  HEPA stands for High Efficiency Particulate Air filter.  It has a 99.97% efficiency at 0.3 micron.  We designed the filter to have a large amount of surface area by pleating the media.  This will extend the life of the filter as well as retain very fine dust contamination inside the drum, not in the surrounding air.  The HEPA filter and vacuum generator are uniquely designed to be incorporated in a modified drum lid that will fit onto a standard 55-gallon, 30-gallon, or 110-gallon drum (209L, 114L, or 418L respectively).   It is also quiet, overall the noise level is only 82 dBA at 80 PSIG (5.5 bar).  Measure that against any electric vacuum.

Model 6199

The Heavy Duty HEPA Vac Systems come in three different packages to best fit your application.  The standard package comes with the drum lid described above and a latching ring to attach to your drum.  It also comes with 10 feet (3m) of an anti-static hose, 20 feet (6m) of a compressed air hose, an aluminum chip wand, a hose hanger, a gauge, and a manual operational valve.  For additional protection, the kit will include a Pre-Filter.  This will wrap around the HEPA filter to capture the “big” items to keep the HEPA media filtering the fine particles.  The standard package is available with three different drum sizes.  For example, model 6199 is for the 55-gallon drum (209L), model 6199-30 is for the 30-gallon drum (114L) and model 6199-110 is for the 110-gallon drum (418L).

Model 6299

The next package is the Deluxe Heavy Duty HEPA Vac System.  This option will include all the items in the standard option plus it adds the heavy-duty aluminum tools, a tool holder and a drum dolly.  The upgraded aluminum tools include a floor tool, crevice tool, skimmer tool with detachable brush, and a two-piece double bend wand.  They can be easily attached to the vacuum hose for quick cleaning of material spills.  The Deluxe system is a great option for getting into tight areas, hard-to-reach places, and large floor areas.  This option is also available in three drum sizes.  For example, model 6299 is for the 55-gallon drum (209L), model 6299-30 is for the 30-gallon drum (114L) and model 6299-110 is for the 110-gallon drum (418L).

Model: 6399

If you do not have a drum to use in your facility, no problem.  EXAIR offers a steel drum in the Premium Heavy Duty HEPA Vac Systems.  The Premium package has all the items in the Deluxe package plus a heavy-duty steel drum.  We offer the Premium option for all three sizes as well.  For example, model 6399 will include the 55-gallon drum (209L), model 6399-30 will included the 30-gallon drum (114L) and model 6399-110 will include the 110-gallon drum (418L).

EXAIR offers some additional items to adjust the Heavy Duty HEPA Vac to perform better in other applications.  We have the Filter Protector which is a very inexpensive filter to help protect the HEPA media.  For materials that are very light and buoyant, like powder paint, the Filter Protector can capture much of this material before it gets to the HEPA media.  Another item that we can offer is the 20 feet (6m) anti-static vacuum hose.  If you need to reach at greater distances with your tools to do a thorough cleaning, this hose can be purchased with your system.

If you get tired of throwing away your electric vacuums for burned up motors, you should try the EXAIR Heavy Duty HEPA Vac System.  They will definitely extend the useful life, make it much quieter to operate and vacuum heavier materials quickly.  For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try the units.  Also, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Heavy Duty HEPA Vac System.  If you want to learn more about our Industrial Housekeeping Products, you can contact an Application Engineer at EXAIR.  We would be happy to help you.

Industrial Vacuums For Most Any Cleanup Need

Vacuum cleaners…most of us think of the electric-powered devices that we clean our carpets at home with. The idea of utilizing vacuum in cleaning applications, however, predates the widespread introduction of electric power by a couple of decades. The original idea was to marry a manual vacuum generating device to a carpet sweeper. These had been around for some time, and they’re still seen today: the beater brush turns as the sweeper is pushed across the floor; it picks up dirt in the brush bristles, and deposits it in an internal receptacle. You’ve probably seen them used in restaurants to tidy up small messes on the floor, in lieu of dragging out the noisy vacuum cleaner while folks are eating.

Anyway, these first vacuum cleaners relied on a bellows, piston cylinder, or other such device that was operated by hand, foot – or, according to one source, a rocking chair – to generate a vacuum. Since it took one person to operate the vacuum generating part, and another to push the sweeper, they weren’t very popular at a time when folks were generally looking for labor SAVING products.

The proliferation of electric power around the turn of the 19th/20th century brought about electric vacuum cleaners.  Most homes have one…including the ‘shop vac’ in my garage, my home actually has three.  These are great for home use; many have long cords that allow you to clean the floors in adjacent rooms without unplugging & re-plugging, and most come with a convenient set of tools for baseboards, furniture, HVAC vents, etc.  For carpet & upholstery, they can’t be beat.

In industrial settings, though, the electric-powered models can find themselves at a disadvantage.  The impellers can clog or break, and the electric motors will, in time, burn out.  If used in wet environments, great care must be used (as with any electric products) or there can be a very real shock hazard.

EXAIR Industrial Housekeeping Products offer a solution to all of these issues.  With no moving parts or electric motors, they are extremely reliable.  If you supply them with clean air, they can run darn near indefinitely, maintenance free.  And no electric power means no shock hazard.

We have a variety of products to meet most any need.  Our Chip Vacs and Heavy Duty Dry Vacs are made for dry material cleanup.  They install (in minutes) on an open top drum, and are available with a variety of accessories…tools, drum dollies, tool holders…even the drum itself if you need one.  The Chip Vac is specified for most ‘general purpose’ jobs; the Heavy Duty Dry Vac is more powerful, and abrasion resistant, for more aggressive needs.  Both exhaust the vacuum air flow through a Filter Bag to contain the particulate in the drum.

The Heavy Duty HEPA Vac features the same high power and rugged construction as the Heavy Duty Dry Vac, but replaces the Filter Bag with a HEPA (High Efficiency Particulate Air) Filter for maximum dust containment.  These are used where critical dust removal, mold & allergen containment, or trapping airborne irritants are called for.

(Left to right) Chip Vac, Heavy Duty Dry Vac, Heavy Duty HEPA Vac
Reversible Drum Vac Family

The Reversible Drum Vac is a two-way liquid pumping system, also made for mounting on standard steel drums…closed top drums, in this case.  They can fill or empty a 55 gallon drum in 90 seconds.  Options include 5, 30, and 110 gallon drum sizes, and a High Lift model – increased suction head for deep wells, underground tanks, or higher viscosity liquids, up to 1,400 cP.

Chip Trapper Systems come complete, ready to go, right out of the box.

The Reversible Drum Vac is also at the heart of our popular and award-winning coolant filtration system: the EXAIR Chip Trapper.  A Filter Bag in the “fill” line traps chips, swarf, and shavings.  The liquid passes through, and is able to be immediately pumped back out.  Not only is coolant life extended, regular cleaning of the coolant sump prevents loss of coolant flow due to clogging of the supply lines.  The Chip Trapper is available in 30, 55, and 110 gallon sizes, and also in the High Lift version.

Speaking of two-way operation, the EXAIR Vac-u-Gun is both a vacuum AND blow gun…simply reverse the orientation of the nozzle insert to reverse the operation:

EXAIR’s Vac-u-Gun transforms in seconds from powerful vacuum to efficient blow gun.

The Vac-u-Gun is an efficient, quiet, and versatile tool with numerous applications, from vacuuming sawdust or shavings, to conveying small parts or pellets, to blowing off chips, water, coolant, or scrap.  And, just in time for Spring Cleaning season, we’re letting you find out just how handy it is, for free – by including one with any qualifying Industrial Vacuum purchase, now through April 30, 2019.

If you’d like to discuss a cleanup application, and how an EXAIR Industrial Housekeeping Product can suit your needs, give me a call.

Choosing the Best Chip Vacuum for Your Application

One Christmas, a long time ago, my Mother In Law gave me a beautifully wrapped present, and a great big smile.  I opened it up…it was an extension cord.  One of those heavy duty orange, indoor/outdoor, 100 foot long models.  I returned her smile, while thinking about all the things I might be able to use it for…and not coming up with anything really solid.

As the family continued to open presents, she disappeared into the other room, and came back with a much larger package and handed it to me…still with that great big smile.  It was a convertible string trimmer; one that worked as a ‘weed eater’ or, with a twist of the handle, an edger.  And it was electrically operated…NOW I knew what the extension cord was for.  As great and useful a gift it was – eighteen years on, and I’m almost competent at edging the sidewalk – I got a valuable lesson from it: accessories make a great gift better.  Since then, I’ve always thoughtfully considered:

  • If I give someone a battery operated gift, I give them batteries too.
  • If it comes with its own rechargeable battery, I carefully open the package and charge it up, before I wrap it up.
  • If accessories are available, I think about how they might use it.  I’ve even presented them with the accessory first, in tribute to my wonderful wife’s wonderful Mom.
  • If there’s a “deluxe” or “premium” version, sometimes it’s worth it to just go all out…again, after consideration of how they might use it.

Now, this is not only the case with presents…many household, commercial, or industrial products offer Deluxe or Premium packages…like the EXAIR Chip Vac System.

At the most basic level, a Model 6193 Chip Vac System for 55 Gallon Drum is all you need to turn an existing drum into a powerful, reliable, durable industrial vacuum.  It comes with a lid & latch ring, Filter Bag, 10 foot vacuum hose, a set of plastic tools, and of course, the Chip Vac itself.  All you need for simple, on-the-spot cleanup purposes.

Model 6193-30 is also available for your existing open-top 30 Gallon Drum.

Sometimes you might have (literally) more ground to cover: the Model 6293 Deluxe Chip Vac System adds a Drum Dolly for mobility, and a Tool Holder to keep the attachments handy.

Deluxe Chip Vac Systems come with a Dolly and Tool Holder in 5 Gallon (left,) 30 Gallon (center,) and 55 Gallon (right) sizes.

Other times, you may just be looking for a complete system, ready to handle everything, right out of the box.  Enter the Model 6393 Premium 55 Gallon Chip Vac System, which adds a heavy duty steel drum, an upgrade to Heavy Duty Aluminum Tools & Static Resistant Vacuum Hose, and a 20ft Compressed Air Supply Hose with Pressure Gauge & Shutoff Valve.

Premium Chip Vac Systems are ready for any cleanup job, right out of the box, and come with 30, 55, or 110 Gallon Drums.

Or, if you’re looking for something lightweight & compact, the Model 6193-5 Mini Chip Vac System comes complete with a 5 gallon drum, and the Model 6293-5 Deluxe Mini Chip Vac System adds a Drum Dolly.

The Mini Chip Vac System comes complete with a 5 Gallon Drum, and the Deluxe System adds a Drum Dolly for mobility.

With no moving parts to wear and no electrical components to burn out, the EXAIR Chip Vac is a virtually maintenance free replacement for noisy, damage-prone electric vacuums.  If you’d like to find out just how handy they are, give me a call.

What’s Wrong With My Reversible Drum Vac? Most Likely – Nothing.

If you need to clean up spills, pump out a sump, or basically just move liquid from one place to another, the EXAIR Reversible Drum Vac is what you’re looking for.  The Model 6196 Reversible Drum Vac System is all you need to turn a closed top steel drum into a powerful two-way pumping system. They’re reliable (no moving parts), durable (stainless steel construction), safe (no electricity), they install quickly, they’re compact, and portable. They’re also very low maintenance…in fact, if you supply the Reversible Drum Vac with clean air, it’ll run maintenance free, darn near indefinitely.

That’s not to say things can’t go wrong…Murphy’s Law still applies…but most anything that can go wrong with the EXAIR Reversible Drum Vac can be identified fairly easily, and remedied fairly quickly. Here’s a rundown of “the usual suspects:”

  • Vacuum leaks.  Even small leaks can be a big problem…a crack or split in the hose, a worn hose cuff, a damaged seal, even a hairline crack in the drum or lid…if air can enter anywhere other than the suction end of the hose, vacuum performance can suffer.  The first thing to do in most any troubleshooting procedure is a visual inspection, and the Reversible Drum Vac is no exception.  We stock the gaskets for the vacuum hose quick connect, as well as the drum lid seals.
Make sure the gasket is clean, in good condition                  The hose cuff should fit snugly on the quick connect
and properly seated.                                                                                             elbow’s barbs.
Pay particular attention to drum lid penetrations.               The drum itself can also be susceptible to corrosion.
All EXAIR Industrial Vacuum drum lids come with an EPDM seal glued in place. If it gets rolled (center) or damaged (right) it’ll need to be replaced to ensure optimal vacuum performance.
  • Compressed air supply, part 1. There are some tight passages in the  Venturi chamber inside the Reversible Drum Vac; this is how the vacuum is generated.  Any contaminants such as dirt or rust can accumulate in these passages, hampering the ability to draw its rated vacuum levels.
    Actual photos of dirt, debris, and contamination we’ve found in Reversible Drum Vacs sent in for Factory Refurbishment Service (ask an Application Engineer for details.)

    Use of a Filter Separator (like our Model 9004 Automatic Drain Filter Separator) with a 5 micron particulate element is recommended.  If the Reversible Drum Vac does get dirty inside, though, it can be cleaned pretty easily…here’s a video that walks you through the process:

  • Compressed air supply, part 2.  The Reversible Drum Vac will produce rated performance when supplied with compressed air at 80psig.  Make sure you can get enough air to it; if your supply line is too long and/or too small in diameter, you’ll get line loss…and poor performance. Use a 3/8″ ID compressed air hose, or a 1/2″ ID if it’s longer than about 10 feet, and avoid any restrictions like quick connect fittings.
  • Compressed air supply, part 3.  If you want to fill the drum a little faster, you can increase the supply pressure to 100psig or so.  Too high of a supply pressure can actually degrade vacuum performance, though.  Excessive pressure can create enough flow to overwhelm the Venturi, hampering its ability to generate vacuum.
  • Safety Shutoff Valve Float.  The Reversible Drum Vac provides overflow prevention via a plastic float that rises when the drum is full.  This breaks the vacuum so that no more liquid can be pumped into a full drum.  When the float rises, you’ll hear a change in pitch.  If you hear this, and the drum isn’t full, remove the Reversible Drum Vac from the drum lid and turn it upside down/right side up a few times.  The float should move freely, all the way from the bottom to the top of its chamber.  If it doesn’t, remove it and make sure the float, o-ring, and the inside of the chamber are clean.  Certain chemicals can cause the float and/or o-ring to swell, which will impede its free movement.  If the body of the Reversible Drum Vac is damaged (pro tip: don’t drop it) that can also cause the float to hang up and not work properly.
If the float doesn’t move freely, remove it (snap ring pliers not included,) clean and reassemble.

Like I said, these are just the first things you want to look for, and it’s highly likely you’re going to solve the problem before you reach the end of this list.  If your Reversible Drum Vac (or any EXAIR product) isn’t giving you the results you’re looking for, though, don’t hesitate to call an Application Engineer.  Chances are, the vacuum unit is just fine and just needs a fresh gasket, a little cleanup, or a new drum. We want to make sure you get the most out of our products.
