About EXAIR’s Deep Hole Vac-U-Gun

The Deep Hole Vac-u-Gun is 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-slot 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-

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.

Air Operated Industrial Vacuum Helps Reclaim Grass Seed and Save Thousands

A customer who produces bags of grass seed were experiencing a large amount of lost product due to spillage during the bagging process. Any spillage they would typically sweep up and throw away. This sweeping would take a good amount of time. Their goal was to determine a way to speed it up the cleaning and see if it was possible to reclaim the seed that was currently scrapped.

8071082079_2f90917891_c.jpg

EXAIR has a broad line of industrial vacuums for a variety of jobs. In this case we recommended our Chip Vac.

EXAIR’s Chip Vac is a compressed air operated industrial duty vacuum designed for vacuuming up dry (or mostly dry) products. The powerful vacuum is suitable for use with metal, wood, or plastic chips and is designed to thread into the 2” NPT bung on standard drum lids. The Chip Vac can handle dry or coolant soaked chips from fixtures, floors and work surfaces of machining centers, lathes, saws, mills, and a variety of other industrial equipment. It was also very suitable for this grass seed application.

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 Chip vac has NO moving parts to wear out, doesn’t require maintenance, and needs nothing but a source of compressed air to operate. In addition, the sound level produced is half of that produced by an electric vacuum.

Chip Vacs-all
From left to right: 5 gallon, 30 gallon, 55 gallon, and 110 gallon Chip Vacs are sized for any cleanup need.

Using the Model 6193 Chip Vac System they were able to reclaim lost product in and around the machines in less time and more efficiently.  While the recovered seed could not be used in their certified premium product, they were able to add it to the “contractors” blend. Saving them around $2,500 annually!

Don’t waste your time, get yourself a vacuum designed for the job. One that’ll last year after year! With these systems in stock, ready to ship with an order by 3:00 ET, a unconditional 30 day guarantee and backed up by our 5-Year Warranty, there’s no reason not to give one a try!

Product Overview – High Lift Reversible Drum Vac

Are you needing to move a thick fluid, move liquid farther or higher? Do you have a below grade sump or pit you’re looking  to empty? Then EXAIR has the solution for you, enter the High Lift Reversible Drum Vac. Like the standard Reversible Drum Vac, the High Lift RDV is a compressed air operated, liquid only vacuum with no moving parts or motors that can fail,  like those in traditional electrically powered vacuums. What separates the High Lift RDV from the traditional version is the higher vacuum it achieves which allows you to lift liquids up to 15′, move liquids up to 20′ and handle fluids with viscosity as high as 1400 centipoise.

The High Lift Reversible Drum Vac is a high powered vacuum able to lift liquids up to 15′ and fill a 55 gallon drum in less than 85 seconds!

The High Lift Reversible Drum Vac features a two-way pump constructed of stainless steel and a built-in safety relieve valve to avoid over pressurizing or over-filling the drum. Air consumption is minimal, at 43 SCFM @ 80 PSIG, while maintaining a low noise level of only 83 dBA. In “empty” mode, the HLRDV achieves a flow rate of 30 gallons per minute (water) to quickly empty the drum.

Systems are available in 30, 55 and 110 gallon capacities in 3 different variations:

The Standard Systems include the High Lift Reversible Drum Vac, shutoff valve, 20′ vacuum hose, standpipe, 90° quick release elbow and aluminum chip wand.

Model # 6195, 6195-30 and 6195-110

Deluxe Systems include all of the items shown above in the “Standard” System and adds a drum dolly, ABS plastic spill recovery kit, (2) extension wands, crevice tool, skimmer tool and a magnetic tool holder.

Model # 6295, 6295-30

And Premium Systems include all of the items in “Deluxe” Systems and adds the drum with lock ring and lid, heavy duty aluminum tools and 20′ compressed air hose.

Model # 6395, 6395-30, 6935-110

Custom Air Amplifiers To Meet Most Any Requirement

When I think of “special” in regard to Air Amplifiers, I’m more inclined to think of the applications they can be used in. I mean, the Air Amplifier itself is about as straight-forward as an engineered compressed air product can be:

Air Amplifiers use the Coanda Effect to generate high flow with low consumption.

Considering the simplicity of the product itself, they can be used for a large variety of “typical” applications:

  • Cooling
  • Drying
  • Cleaning
  • Ventilation
  • Fume Exhausting
  • Dust Collection

There are no shortage of “special” applications either.  They’re used successfully in Air Operated Conveyance applications (when the stronger vacuum head of a Line Vac isn’t required) and we’ve even got a customer who uses one instead of an E-Vac Vacuum Generator for a “pick & place” operation…they’re picking up small, porous fiber discs (sort of like a coffee filter) one at a time, and the E-Vac wanted to pick up a good part of the whole stack, no matter how low they turned the pressure.  And of course, I can’t think of anything more special about Air Amplifiers than this:

You have to read it to believe it.  Follow the link and click on “Case Study: Roaring Banana Breath”

With fifteen distinct models to choose from in a range of sizes (3/4″ to 8″,) materials (aluminum or Stainless Steel) and even a High Temperature model that’s rated to 700°F (374°C), we’ve still made a fair number of Custom Air Amplifiers too…thirty-four, to be exact, as of this writing.

I won’t bore you with all the details – I can’t, actually, because some of them are proprietary* – but here are some “regular” examples of “special” accommodations:

  • Connections: EXAIR Air Amplifiers have smooth bores on the inlet & outlet plenums that you can hose clamp a hose (or round duct) to if you need to get air flow from, or to, one place or another.  Sometimes, though, they’re going in to an existing system, so we’ve made them with flanges (150#RF and Sanitary Tri-Clamp, for example) or threads (NPT or BSPP.)  If you want to use something other than a standard hose or duct line, we can help.
  • Material of construction: Our durable, lightweight aluminum Super & Adjustable Air Amplifiers are just fine an awful lot of the time.  Our type 303 Stainless Steel Adjustable Air Amplifiers will hold up to heat and corrosives.  We’ve also in PTFE (Teflon™) as well as a range of metal alloys to meet specific corrosion or wear conditions.  If your environment calls for a little something extra, we can help.
  • Assembly: Super Air Amplifiers are fitted with a stock shim that gives you published performance.  We’ve got other thicknesses, though, if you need more (or less) flow, though.  Adjustable Air Amplifiers are, well, adjustable…you just thread the plug in/out of the body until you get the results you want.  Sometimes the user knows what shim they want in a Super Air Amplifier, or what gap their Adjustable Air Amplifier needs to be set to, and we can assemble it accordingly.  If you have a ‘tried-and-true’ performance setting and want it met right out of the box, we can help.
  • Assembly, part 2: Good engineering practices call for lubrication on O-rings and threaded connections, and we use high quality, general purpose compounds when assembling our Air Amplifiers.  These are detrimental, however, in certain situations (silicone exclusion areas, I’m looking at you.) If certain chemicals or compounds are prohibited by your application, we can help.

*Let’s say you’ve done the “heavy lifting” to call out one (or more) of these special design features.  If we make a custom product (and that’s not just Air Amplifiers, by the way) using directions based on your time and labor, we’ll treat that product as proprietary to you, and you alone.

EXAIR has 208 catalog pages worth of Intelligent Compressed Air Products on the shelf…8 of those pages are our Air Amplifiers.  If you want to talk about customizing one to meet your needs, give me a call.
