EasySwitch Wet-Dry Vac with HEPA Filter

Published on by Russ BowmanLeave a comment

When I bought my first house (I was a happy condo dweller prior to the birth of my second son), I got a gift card for a home improvement store from some of the folks I worked with. Since my mother-in-law had already bought me a lawn mower, I used that gift card to purchase another staple of the Suburban Dad’s Garage: a heavy duty wet-dry shop vac. It quickly proved its usefulness as a dry vac in cleaning up after a couple of wood working and plumbing (mis)adventures, and as a wet vac following a sump pump failure & subsequent replacement. That last part was when I learned a valuable lesson about the filter cartridge that catches dirt, debris, sawdust, PVC shavings, copper shavings & solder slag: it gets ruined, and makes a HUGE mess inside the drum, if you don’t take it out before pumping the residual water from your basement sump.

I’d like to say that never happened again, but I had the old “there’s got to be a better design” thought every time I carefully positioned a large trash bag underneath so I could finagle a waterlogged & debris-laden filter out of my shop vac canister without making an even bigger mess on the floor. Now, I don’t believe this had anything to do with our R&D engineers’ development of the EasySwitch Wet-Dry Vac, but it IS an amazing coincidence…

Not that it’s particularly difficult to change the filter in my shop vac, but this is indeed an “Easy Switch”.

If you’re looking for a powerful, reliable, and easy to use industrial vacuum, here it is. Made to fit a standard 55 gallon open top drum, the EasySwitch Wet-Dry Vac Systems come in a variety of configurations to meet your specific Industrial Housekeeping needs:

  • If you have a drum, the EasySwitch Wet-Dry Vac kit comes with everything you need for basic operation:
    • The EasySwitch Wet-Dry unit itself
    • Drum Lid with filter hatch
    • Standard or HEPA filter & pre-filter
    • 20ft compressed air hose, pressure gauge, and shutoff valve
    • 10ft vacuum hose, crevice tool, straight wand, skimmer tool, and dust brush
  • For portability and convenience, the Deluxe system adds:
    • Drum dolly
    • Upgrade to anti-static vacuum hose and Heavy Duty Aluminum Tools
    • Spill Recovery Kit (for floor cleanup of liquids)
    • Magnetic Tool Holder
  • And if you need a drum, the Premium system adds that as well.

The standard filter is suitable for general purpose dry vacuuming, but for critical dust removal, our HEPA filter conforms to IEST-RP-CC-007 specifications for minimum 99.97% filtration at the 0.3 micron level. If your cleanup involves toxic materials, respiratory irritants…anything that people shouldn’t be breathing…you’ll definitely want the HEPA filter.

For critical dust containment, the award winning HEPA EasySwitch Wet-Dry Vac System is your durable, reliable, compressed air operated solution!

And, of course, you can still remove the filter (don’t forget that part; that’s how this blog started) for high performance liquid vacuuming as well. If you’d like to find out more about the HEPA EasySwitch Wet-Dry Vac – or any of our other Industrial Housekeeping Products – give me a call.

EXAIR’s Heavy Duty HEPA Vac

Published on by Tyler DanielLeave a comment

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.

The HEPA Filter Protector

Published on by johnball2014Leave a comment

With our Heavy Duty HEPA Vac, it is very capable of capturing particles that are very small. You do not have to worry about re-entraining the dirt that you vacuumed back into the air. The filtration efficiency of the HEPA filter is 99.97% at 0.3 micron. Because it is so efficient, we place a prefilter on the outside of the element. This helps to capture the larger particles so that they do not prematurely plug the HEPA media. In extreme conditions with large amounts of debris, we do have another option. It is the model 901373 filter protector. It is a bag that will go on the outside of the prefilter and the HEPA filter. With a large influx of contamination, the filter protector will create a matrix from the contamination to create a cake. This cake, as it builds, will start to capture smaller particles and become more efficient. It is similar to a natural dam after a big rain. The large boulders and logs collect into a section, and then the smaller rocks and branches will collect behind it.

Under normal conditions, the standard HEPA filter with prefilter will last you for a while before replacing. It is dependent on the amount of dirt that is being collected. But, in those extreme conditions, you do not want to change the HEPA filter every week. This would be too expensive. That is why EXAIR found a cost-effective option to help, the filter protector. The model 901373 filter protector can be changed in a matter of minutes and the cost is less than 2% of the HEPA filter. Just like disposable shoe covers, they are inexpensive and they protect your expensive shoes. If you require any more information on our Heavy Duty HEPA Vac or the accessories, you can contact one of our helpful Application Engineers at EXAIR.

Heavy Duty HEPA Vac Reduces Dust When Vacuuming

EXAIR Heavy Duty HEPA Vacuum Systems

When selecting the proper EXAIR vacuum system for an application, several details are considered by our Application Engineers.  For example:

Does the vacuum need to vacuum liquids or solids?

If the need is to vacuum solid material, what is the approximate size of the material pieces?

How quickly does the material need to be vacuumed?

What is the compressed air supply available?

Is dust a major concern?

The last question becomes more relevant with finer material, especially dust or small dirt particles.  Many applications have a need for dust control and need a vacuum system capable of maintaining low dust levels.

The EXAIR Heavy Duty HEPA Vac was designed for this exact purpose.  With a HEPA filter that is tested in strict accordance to IEST-RP-CC-007 standards to provide a minimum of 99.97% filtration at the 0.3 micron level, the Heavy Duty HEPA Vac can provide an effective and highly efficient vacuuming method using only compressed air.

Fine Powder Hopper 2
Hopper used for fine powder collection

For example, in the fine dust collection hopper shown above, the hopper undergoes regular cleaning and maintenance which includes a thorough cleaning to remove any fine dust remaining in the hopper. This powder has a tendency to permeate the filtration used in most vacuums, and electrically powered units have continuously failed.

The Heavy Duty HEPA Vac is a perfect fit for this application need as it can provide adequate filtration, and it has no moving parts to wear out.

If you have a dusty or difficult vacuum application in need of a sustainable vacuum system, contact an EXAIR Application Engineer to discuss the Heavy Duty HEPA Vac.
