Compressed Air Vacuums and Their Advantages Over Electric Vacuums

EXAIR‘s line of Industrial Housekeeping Products consist of liquid and dry vacuums that utilize compressed air to operate. They do not have loud electric motors which most ‘all purpose’ electric vacuums rely on.  In industrial settings with harsh conditions and rugged use, EXAIR’s Industrial Housekeeping Products are better suited for the everyday wear and tear of typical manufacturing, commercial and construction environments.

When you look at EXAIR vacuums, you’ll notice there is not an electrical cord.  Because the EXAIR Industrial Housekeeping Products utilize compressed air for operation. This means they do not have the same maintenance issues of an electric motor which breakdown and fail when dirt, dust and temperature take their normal toll on moving parts. With EXAIR vacuums there are no moving parts: no motors to burn up, no bearings to wear out, and no impellers to clog in the vacuum units. They also run quieter than a typical electric vacuum.

They are maintenance free, just supply clean and filtered air, and they can operate for many, many years.

 

EXAIR’s liquid vacuums, there is a built in pressure/vacuum relief device and auto safety shut-off to prevent over-filling.

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.

The heart of our popular 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.

EXAIR’s dry vacuums provide many pickup and filtration options. They withstand harsh environments, have many filtration and power options and run quieter than electric vacuums.

The EXAIR Chip Vac and Heavy Duty Dry Vac is a powerful industrial vacuum for use on wet or dry chips. Both are for use with 30, 55, or 110 gallon drums, and the Chip Vac can also be used on a 5 gallon drum. The Heavy Duty HEPA Vac 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.

The Chip Vac is also 50% quieter than a comparable electric vacuum at only 77 dBA!!

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.

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.

Reversible Drum Vac Quickly Empties Sump In Close Quarters

I had the pleasure of talking with an operator in a power generating plant recently. A small sump, in a hard-to-access location, needed to be emptied periodically, or it would overflow and make a big mess. They didn’t have room for a “great big” (his words) 30 or 55 gallon drum, and it was difficult to use an electric shop vac because there wasn’t an outlet nearby (it’s a very humid location in the steam plant) so they had to rig an long extension cord through a doorway and down to the lower mezzanine.

They DO have compressed air available…in fact, there was an unused port on a manifold that supplied other pneumatic equipment, right next to the sump. He thought it sounded like an ideal application for the Mini Reversible Drum Vac.

And it was. They put a Model 6196-5 Mini Reversible Drum Vac System on the floor, next to the sump, and empty it (usually 1-2 gallons) on the night shift. They also got a 6569-20 20ft Vacuum Hose, which they use to pump the drum contents into an internal drain system.

Reversible Drum Vac systems are available from 5 to 110 gallon capacity

No more hassles with the electric shop vac and extension cord. No more overflow messes. The most they have to do now is change to the 20ft hose when they empty the drum.

EXAIR Industrial Housekeeping Vacuums – A Look at the Advantages Over Electric Vacuums

EXAIR‘s line of Industrial Housekeeping Products consist of liquid and dry vacuums that utilize compressed air to operate. They do not have electric motors which most ‘all purpose’ vacuums rely on.  In industrial settings with harsh conditions and rugged use, the Industrial Housekeeping Products are ideally suited for the everyday wear and tear.                               6091   6095.jpg

The heart of the EXAIR liquid type vacuums, like the Reversible Drum Vac, the High Lift Reversible Drum Vac, and the same range in the Chip Trappers is shown here. Installing onto an any closed head, 30, 55, or 110 gallon drum creates a high powered vacuum.  It can fill a 55 gallon drum in less than 2 minutes.  Then, with the turn of a knob, the the same pump quickly empties the drum. Useful for refilling coolant sumps, vacuuming floor spills, or transferring contaminated liquids to filtration tanks in minutes.  Flow rate can be controlled with the knob.  The Chip Trapper has an internal filtration system to separate the chips from the coolant, allowing for disposal of the solids, and for pumping of the clean coolant back into the sump.

When you look at the vacuum producing units, you’ll notice there is not an electrical cord.  Because the EXAIR Industrial Housekeeping Products utilize compressed air for operation, they do not have the same issues with wear, breakdown and failures as electrical type vacuums. There are no moving parts in the vacuum units to wear out or break.  They are maintenance free, just supply clean, dry air, and they will operate for a long time. For the the liquid type systems, there is a built in pressure/vacuum relief device and auto safety shut-off to prevent overfilling.

There are no motors and bearings to wear out and no impellers to clog.  The Chip Vac is 50% quieter than a comparable electric vacuum.  Safety is a top priority, and the use of the unit on wet floor and spills is not an issue.
