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.

Deep Hole Vac-u-Gun – Blow Chips Loose and Vacuum Them Away in One Step!

Last week, we looked at the Vac-u-Gun, and you can take a look at that blog here.

This week I wanted to present the Deep Hole Vac-u-Gun, a special iteration of the Vac-u-Gun, designed to provide a solution to the troublesome process of cleaning cavities and drilled holes.

The Deep Hole Vac-u-Gun is a low cost solution to quickly remove chips and debris from grooves and drilled holes where blow gun could create potentially hazardous flying debris. The Deep Hole Vac-u-Gun is simply positioned over the hole, and the trigger squeezed and then a small blow tube delivers a a stream of air to dislodge and lift the chips while the large suction tube vacuum them away. The operator is protected form flying debris since all chips and debris is contained within the clear suction tube. The device is capable of cleaning holes up to 1-1/4″ (32mm) diameter and 18″ (457mm) deep!

How does the Deep Hole Vac-u-Gun work?

How the Deep Hole Vac-u-Gun Works

 


Compressed air, normally 80-100 PSIG (5.5 – 6.9 bar), flows through the inlet (1) into an annular plenum chamber (2) when the trigger is pressed. A small amount of air is injected into the blow tube (3) to provide agitation and lift to the chips or debris. The larger airflow is injected into the the throat of the gun through directed nozzles (4). The jets of air create the vacuum at the intake (5) which draws the material in and accelerates it through the unit. The chips, debris or other particulates can then be exhausted into a filter bag or hose attached to the Deep Hole Vac-u-Gun System.


 

We have found many applications where the Deep Hole Vac-u-Gun is beneficial- including removing chips and debris in:

Holes in fixtures, drilled plastics, T-slots’groove cleaning , coolant evacuation from parts, woodworking, tapped holes, cavity evacuation, and many more!

There are many advantages to the Deep Hole Vac-u-Gun, and some are:

Low cost, no moving parts/maintenance free, durable die cast construction, eliminates shock hazard – no electricity, meets OSHA pressure requirements, safe operation – no flying chips, lightweight and portable, and quiet.

The Deep Hole Vac-u-Gun uses less compressed air than ordinary blow guns, and the amplified output flow is 12 times the air consumption rate.

Deep Hole Vac-u-Gun Specifications

Note that the Deep Hole Vac-u-Gun should not be operated without a filter bag or vacuum hose attached to the exhaust.

There are three (3) Deep Hole Vac-u-Gun System options-

Deep Hole Vac-u-Gun Systems

The Model 6094 is the Deep Hole Vac-u-Gun only.

The Model 6194 comes with a reusable bag and clamp for debris collection.

The Model 6394 comes with the reusable bag and a 10′ (3m) section of vacuum hose for transferring the debris to a collection point.

If you have questions about the Deep Hole Vac-u-Gun or any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

Shot Blasting Media and Dust Problems Solved with EXAIR’s HEPA Vac

Heavy Duty HEPA Vac Family

Have you ever heard an electric vacuum toward the end of its life?  It gets an irritating high-pitch noise caused by the bearings going out.  A customer was hearing this annoying sound after only two months of use.   Their application was shot blasting metal parts.  The shot blast media was very dusty and carried everywhere around the room.  After use, they would use a shop vac to clean the machine and around the area.   When they started to hear that “moan” from their electric vacuum, they knew that they would have to purchase another unit.  Additionally, they noticed a lot of dust migrating into the work environment from the shop vac, creating a breathing hazard for the operators.  After their second electric vacuum failed, they started looking for a better choice.

Sand Blasting Equipment

When they contacted EXAIR about these issues, EXAIR had a great solution for them.  I recommended our model 6399, 55-gallon Premium Heavy Duty HEPA Vac System.  This system comes with a drum, drum dolly, heavy duty accessories, HEPA Filter, and a robust vacuum system.  The heavy-duty accessories are easy to use to vacuum in tight spaces.  The HEPA filter inside the drum has an efficiency of 99.97% at 0.3 micron.  So, the dust will remain in the drum and not migrate back into the ambient air.  The HEPA filter media is pleated to give a large surface area of 36.7 ft2 (3.4 m2).  Packed inside a supported cylindrical, it will allow for great amount of debris before changing.  With the shop vac above, the surface area of the filter was very small causing the filter to plug and under-perform.  The EXAIR Heavy Duty vacuum generator is made from a hardened-alloy steel construction which is very resistant to wear.  It does not have any moving parts or bearings to wear.  For this application, the generator is perfect for the shot blast media.  The Heavy Duty HEPA Vac only requires compressed air to operate, not an electric motor which can fail from dusty environments.  The Heavy Duty HEPA Vac System only has a decibel level of 82 dBA which makes it very quiet compared to shop vacs.  With clean compressed air as the engine for the vacuum, this system can last for years; not months.

When the company above started to use the Heavy Duty HEPA Vac, the first thing that they noticed was how quiet it operated.  That constant loud noise from their electric vacuum was gone, making it a better working environment for the operators.  They also noticed that the dust was not getting back into the environment, reducing the dust nuisance.  If you find that your electric vacuums are breaking down or you would like to reduce the noise levels, EXAIR has a large line of Industrial Housekeeping Products.  You can contact an Application Engineer to see if we have the right vacuum product for you.

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 Vacuums: Dry Vacuums

Our Industrial Housekeeping vacuums utilize compressed air energy to create a powerful and effective vacuum capable of with standing the harshest of environments. These vacuums have no moving parts to wear out or replace, run quietly and are built to be placed upon your own drum or may be purchased with a drum.

EXAIR has three dry/solid vacuum systems available they are the Chip Vac, Heavy Duty Dry Vac and the Heavy Duty HEPA Vac.

The EXAIR Chip Vac picks up wet or dry chips and delivers them directly into an ordinary open-top drum.  The Chip Vac is used to clean chips from fixtures, floors and work surfaces of machining centers, lathes, saws, mills and other industrial equipment.  The Chip Vac is the ideal choice for quick and efficient cleaning.  The Chip Vac can also be used to vacuum wood or plastic chips and can be used occasionally for dusty materials since it incorporates a filter bag to keep the surrounding air clean.

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

chipvac_family
5, 30, 55, and 110 Gallon Chip Vacs

The Heavy Duty Dry Vac like the Chip Vac can attach to ordinary open-top drums.  Designed to withstand tough industrial environments the proprietary hardened alloy pump deliver powerful performance with superior abrasion resistance.  They are used for a wide variety of applications that include abrasive materials such as steel shot, garnet, metal chips and sand!  Please know that while very powerful it is still suitable for general applications such as vacuuming floors, machines, work stations and industrial equipment.

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

6397
Available in 30, 55 & 110 Gallon Sizes

Finally 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.  Like the Chip Vac and the Heavy Duty Dry Vac it will attach to ordinary open top drums as well.

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

6399
Available in 30, 55 & 110 Gallon Sizes

When you look at the EXAIR vacuum producing units, you will notice there is not an electrical cord.  That is because the EXAIR Industrial Housekeeping Products utilize compressed air for operation, therefore they do not have the same issues with wear, breakdown and failures as electrical type vacuums. Quite simply there are no moving parts in the vacuum units to wear out or break.  They are maintenance free, just make sure the air supply is clean & dry, and they will operate for a long time due to the fact that there are no motors and bearings to wear out and no impellers to clog.

If you would like to discuss Industrial Housekeeping or any EXAIR product,  I would enjoy hearing from you…give me a call.

The Case for the Chip Vac

EXAIR Chip Vacs come in a range of sizes, and options, to meet the needs of most any clean up job.

The season for spring cleaning – spring, that is – is upon us (here in the Northern Hemisphere anyway) so it’s time to start looking for ways to make the task as easy and hassle-free as possible. That’s my take, anyway…and if you feel the same trepidation (or maybe even dread) as me, then this blog is for you. If you are one of those people who LIKES cleaning (you know who you are,) there’s something here for you too.  Without further ado, let’s talk about the EXAIR Chip Vac Systems.

The first thing you should know is that, like all EXAIR Intelligent Compressed Air Products, Chip Vac Systems are compressed air operated.  Why is this important?

*Safety – there’s no electric power cord or cable to trip over, damage, or get wet…all of which can be an electrocution hazard.

*Consistency – unlike a typical shop vac, which has a motor driven impeller/propeller to generate the vacuum flow, the Chip Vac creates powerful direct flow action from the compressed air supply.  With no moving parts in the way, there’s nothing to trap debris or clog the line.  If it can fit through the hose, the Chip Vac can suck it into the drum.  Every time, all the time.

*Reliability – electric motors can overheat and burn out if you run them continuously for long periods of time – or if you start and stop them frequently.  Not so with the Chip Vac…it’s pulling rated vacuum and flow as soon as you cut in air to it.  And if you supply it with clean, dry air, the Chip Vac will operate darn near indefinitely, maintenance free.

At EXAIR, our motto of being “easy to do business with” applies to not only all aspects of Customer Service and Technical Support; it’s even integral to our systems design.  What does this mean for the Chip Vac?

*Versatility – we make Chip Vac Systems for 30, 55, or 110 gallon drums.  If you don’t already have an open top drum to install one on, we can supply the drum too.

*PortabilityDeluxe Chip Vac Systems come with a dolly for your drum, so you can roll it wherever you need it.  The 30 Gallon Chip Vac Systems are compact enough to fit through just about any passageway that you can walk through.  But in tighter constraints…

*Portability, part 2Mini Chip Vac Systems come complete with a 5 gallon drum that can be easily carried or lifted to just about anywhere you need it to go.  The Deluxe System even comes with a dolly, for total portability.

*Resourcefulness – because they fit standard drums, they’re easy to move from one drum to another.  This is of particular value to machine tool operators who work with different materials: they can use the Chip Vac on one drum to vacuum up aluminum chips from one job, and then move it to another to clean up stainless steel chips from another job.  This makes recycling quick, easy, and profitable.

If you’d like to find out more about how EXAIR Chip Vac Systems – or any of our Industrial Housekeeping Products, can improve the efficiency and safety of your cleaning tasks (Spring or otherwise,) give me a call.

EXAIR Heavy Duty Dry Vac: Overview

Heavy Duty Dry 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 Dry 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 Dry Vac is used to vacuum solid materials like plastic, sand, and even denser materials like steel shot.  The vacuum pumps are made from a hardened alloy construction to resist wear and abrasion, and it is designed to generate a strong 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 Dry Vac Systems with different options and drum sizes.

The unique design of the Heavy Duty Dry Vac is incorporated in the modified lid that will fit onto a standard 55-gallon, 30-gallon, or 110-gallon drum (209L, 114L, or 418L respectively).  A 0.1-micron filter bag mounts in the center of the lid to allow excess air to escape and to contain the contamination inside the drum.  The large surface area of the filters allows for extended use before replacement while the high efficiency will keep the fine particles from re-entering the environment.  Under the drum lid, EXAIR used some features to help reduce the noise level even further.  We added a silencing foam and an extended hose.  This will muffle the noise and direct the contamination toward the bottom of the drum.  With these additional features, the noise level is only 82 dBA at 80 PSIG (5.5 bar).  Measure that against any electric vacuum.

Heavy Duty Dry Vac System

The Heavy Duty Dry Vac Systems come in three different options to best fit your application.  The standard option comes with the drum lid described above and a latching ring to attach to the 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.  This option is available with three different drum sizes.  For example, model 6197 is for the 55-gallon drum (209L), model 6197-30 is for the 30-gallon drum (114L) and model 6197-110 is for the 110-gallon drum (418L).

Deluxe Heavy Duty Dry Vac System

The second option is the Deluxe Heavy Duty Dry Vac System.  This option will include all the items in the standard option plus 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 are easily attached to the 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 6297 is for the 55-gallon drum (209L), model 6297-30 is for the 30-gallon drum (114L) and model 6297-110 is for the 110-gallon drum (418L).

Premium Heavy Duty Dry Vac System

If you do not have a drum to use in your facility, no problem.  EXAIR offers a steel drum in the Premium Heavy Duty Dry Vac Systems.  The Premium package has all the items in the Deluxe option plus a heavy-duty steel drum.  We offer the Premium option for all three sizes as well.  For example, model 6397 will include the 55-gallon drum (209L), model 6397-30 will included the 30-gallon drum (114L) and model 6397-110 will include the 110-gallon drum (418L).

If you get tired of throwing away your electric vacuums for burned up motors, you should try the EXAIR Heavy Duty Dry Vac System.  They will definitely extend the useful life, make it much quieter to operate and vacuum denser heavier materials quickly.  For U.S. and Canadian customers, we offer a 30-day unconditional guarantee to try the units.  If you need help to determine which Heavy Duty Dry Vac option would best suit your application, you can contact an Application Engineer at EXAIR.
