EXAIR’s Heavy Duty HEPA Vac

March brings with it the first day of spring. I don’t know about you, but boy am I ready for some warmer temperatures!! Naturally, spring is the time of year that we roll up our sleeves and do some of the deep-cleaning we’ve been putting off all winter. Lucky for you, EXAIR has an entire line of Industrial Housekeeping Products that’ll get your shop cleaned up for spring. With no moving parts to wear out and no electrical requirement, these products are Built to Last. For applications requiring you to vacuum very fine or dusty materials, look no further than EXAIR’s Heavy Duty HEPA Vac.

HEPA Vacuum

Electrically powered vacuums or shop vacs are not designed to be operated in a rugged industrial environment. Filters clog, motors wear out, and you find yourself frequently replacing them. EXAIR’s Heavy Duty HEPA Vac has NO moving parts to wear out, doesn’t require maintenance, and needs nothing but a source of compressed air to operate. A static resistant hose also prevents painful shocks when working with dry, dusty materials.

The vacuum generator is constructed of a hardened steel alloy designed to be resistant to abrasion and delivers a powerful vacuum level of -60” H2O at 80 PSIG. The lever lock drum lid fits any open top 30, 55, or 110 gallon drum. Moving the system from one drum to another can be done quickly, allowing you to keep different materials separate for recycling. Recycling companies will pay a premium for pre-sorted materials, allowing you to get more out of your otherwise scrap material. It can be used with any open head steel, fiber, or plastic drum in good condition (ANSI Standard #MH2-2004).

If you don’t have a spare drum available, not to worry! EXAIR also sells a Premium Heavy Duty HEPA Vac System that will include either a 30, 55, or 110 gallon drum and dolly.

The HEPA Vac works by injecting compressed air at 80-100 PSIG through the air inlet (1) and into an annular plenum chamber (2). It is then injected into the throat through precisely directed nozzles (3). These jets of air create a vacuum at the intake (4) which draws in material through the generator itself (5), directing it into the bottom of the drum. The airflow is passed first through a pre-filter to trap larger particles, and then through the 0.3 micron HEPA filter, trapping any airborne particles. It is then exhausted through the vent in the top of the drum lid (6).

You wouldn’t use a hammer to try and drive in a screw, so don’t try and force a shop vac or electric vacuum to deal with these harsh materials. Get yourself the right tool for the job and give an EXAIR Vac a try. With a 5 Year Built to Last Warranty, there really is no comparison. Act fast, between now and May 31, 2020 we’ll include a FREE Model 6492 Vac-u-Gun System to any US and Canadian order.

From now through May 31, 2020, we are offering a FREE Vac-u-Gun with any order for one of our Industrial Housekeeping Vacuum Systems. The Vac-u-Gun is a multi-purpose tool that can be used to vacuum or transfer material from one location to another or it can be used as a powerful blow gun to clean debris off of the surface of a part or workstation. There is no electricity required to operate and no moving parts to wear out, providing for a safe, maintenance free operation.

EXAIR Vac-U-Gun

Our systems are designed to be either solids handling or liquid handling.

Our Chip Vac Systems are the ideal choice when looking to vacuum dry or damp debris left over from machining operations and delivers them to a standard open top steel drum. For more abrasive material, such as sand or steel shot used in sandblasting processes, the Heavy Duty Dry Vac provides superior wear resistance due to it’s proprietary hardened alloy construction.

If you are looking to vacuum liquids we offer our Reversible Drum Vac and High LIft Reversible Drum Vac providing higher suction lift, up to 180″ H2O.

Our Chip Trapper and High Lift Chip Trapper are also used in liquid applications but these systems incorporate a filter bag inside the drum to capture any suspended solids in the liquid so only clean fluid is pumped back into the reservoir or tank.

In dusty applications we offer the Heavy Duty HEPA Vac which uses the same vacuum as the HD Dry Vac but this system provides a higher level of filtration meeting HEPA requirements of 99.97% filtration at the 0.3 micron level.

Heavy Duty Pneumatic Vacuums: EXAIR’s Heavy Duty Dry Vac

Are you tired of not being able to pick up your heavier material with your current vacuum? Is your material abrasive, does it have a high bulk density? Are you tired of your electric vacuum constantly burning up its motor? EXAIR’s Heavy Duty Dry Vac system is engineered with the power to vacuum heavy materials, materials with high bulk densities. It’s material resists abrasion from the harshest of debris, like garnet, glass, tumbling media and steel shot. This system has no moving parts which means no motors or bearings that can fail on you.

The Heavy Duty Dry Vac requires only 68 SCFM at 80 psig of compressed air to operate. Using a hardened alloy construction for the vacuum generator gives the system an increased resistance to abrasive material including sand and blasting material. Depending on your application and the volume of material you need to vacuum we provide 3 different sizes, 30-gal, 55-gal, and 110-gal.  

Heavy Duty Dry Vac in operation

The design of the Heavy Duty Dry Vac allows the system to be mounted on your own drum and has a 0.1-micron filter bag installed on the center of the drum to allow air to escape and keep the material inside the drum. The enlarged size of the filter bag allows it to last longer before needing to be cleaned and/or changed out. Under the lid EXAIR has design features to aid in lowering the sound level down to only 82 dBA.

The Heavy Duty Dry Vac system comes in three different kits; these kits are the Standard, Deluxe, and Premium systems. The basic kit come with the Vacuum generator, the lid, and a lock ring to seal the lid onto your drum. The kit also includes the filter bag, 10’ Static resistant hose, and the aluminum chip wand. The basic system is everything that you need to get started with your own drum.
The Deluxe system Includes everything that the basic Heavy Duty Dry Vac system comes with but adds a few items: A magnetic tool holder, a 2-piece double bend wand, 12” floor tool, 11” crevice tool, 24” crevice tool, a skimmer tool with a detachable brush, and a 3-1/2” diameter bust brush with conductive bristles. All of the tools that come in the Deluxe system are of Aluminum construction. This system also adds the drum dolly to make it easier for you to move the system around.

If you do not have your own drum the Premium system includes everything Deluxe system does except adds a drum. Each Drum vac system comes in one of the 3 sizes listed.
For more information on EXAIR’s Heavy Duty Drum Vacs or any EXAIR‘s 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.

Solving Performance Issues of Air Operated Industrial Vacuums

This blog will focus on the EXAIR Chip Vac, but the troubleshooting process and steps for achieving optimal performance are consistent among EXAIR’s entire line of air operated industrial vacuums.

There’s really not that much that CAN go wrong with an EXAIR Chip Vac System. They have no moving parts to wear or electrical components to burn out. As long as they’re supplied with clean air, they’ll run darn near indefinitely, maintenance free.

Murphy’s Law, of course, is still in full force, so if something CAN go wrong, it WILL go wrong.  The Chip Vac is, alas, no exception.  Good news is, because of the Chip Vac‘s simplicity, troubleshooting is simple as well.  The most common problems we see with ANY of our engineered compressed air products (not just the Industrial Vacuums) are related to compressed air supply:

  • New users might not consider the air demand required by a new product, and may provide an inadequate supply line.  The Chip Vac, for example, will consume 40 SCFM @80psig for rated operation, and will need a 1/2″ (inside diameter) hose to supply that, assuming a length of no more than 20ft.  Hooking one up to a common 3/8″ hose on a 50ft reel, for example, will “starve” the Chip Vac, resulting in degraded performance.
  • Also, the preferred method of connection is a hose with threaded fittings on the ends.  A local hydraulics/pneumatics shop can likely make these, while you wait.  Push-to-connect quick connect fittings are restrictive by nature, and should be avoided.  Quarter turn claw-type fittings are great…the main drawback (which can be solved with an upstream shutoff valve) is the line has to be depressurized to make or break the connection.
  • If you absolutely want to use a push-to-connect type, you can oversize it (use one made for larger hose with, say, 3/4 NPT fittings) and use bushing/adapters to get to your actual hose size.

    If you must use quick connects, the 1/4 turn claw type (left) is the least restrictive. Push-to-connects (center) are likely to starve your product, unless you oversize them (right) like we do in our Efficiency Lab.
  • Speaking of supply issues, make sure nobody’s bumped into a valve handle & partially closed it (I have,) ignored the maintenance schedule & didn’t change a clogged filter element (I have,) or ran something into a copper line hard enough to crimp it, but not rupture it (I haven’t…that was Tim, who, aside from this incident, was really pretty good with a forklift.)

The issues above apply to not only any compressed air system, but most fluid power/fluid handling systems.  Since this blog is about Chip Vac troubleshooting, let’s move on to some specifics.  If you’re sure you’re getting proper air supply to the Chip Vac (by the way, a pressure gauge right at the inlet – like the one that comes with our Premium Chip Vac System’s air hose – will eliminate any doubt,) then let’s look at some potential issues downstream:

  • Dirt & debris can collect inside the Chip Vac itself, obstructing the outlet holes, and lowering your vacuum flow.  You can disassemble and clean it pretty easily, though.
  • The Filter Bag can get clogged, especially if you’re vacuuming up a lot of dust or powdery materials.  If this happens, turn the Chip Vac off and shake the Filter Bag to dislodge the material, allowing it to fall back into the drum where it belongs.
  • Speaking of which, if you find that, all of a sudden, the Filter Bag is clogging, remove the drum lid and check for the Silencing Hose.  This serves two functions…the first is in the name (just a little discharge hose mitigates the sound level of the Chip Vac‘s exhaust flow.)  Secondly, it directs the vacuumed material positively into the drum, limiting the amount that is “dust-storms” in the upper area of the drum, where it’s more prone to make it into the Filter Bag.

Pro tip: check for the Silencing Hose when you remove the lid to empty the drum. DON’T throw the Silencing Hose in the trash.

I’m not going to unequivocally state that this is an all-inclusive list (see “Murphy’s Law,” above,) but these are the Usual Suspects if you’re just not getting the most out of your Chip Vac.  If you ever have any questions, though, give us a call.  We’re here to help.
