I was recently contacted by an automotive parts manufacturer that was looking for a solution for cleaning out blind holes in a variety of machined parts. After discussing the application, we settled on a 1697SS-6-CS VariBlast Compact Safety Air Gun with Pico Nozzle, 6” Extension, and a Chip Shield. The small M5 nozzle at the tip of the gun allowed them to insert it inside of the hole and dislodge the hard-to-reach chips inside of the holes.
This worked very well for removing the chips, but they were encountering an unexpected issue as these chips were now getting lodged in other areas of the part as they were ejected. They then had to visually inspect the entire part after each blowoff to ensure that everything was completely removed.
What they thought to be an ideal solution, ended up not being the best fit. They gave us a call back to inquire about an alternative solution. We offer another product, the Deep-Hole Vac-U-Gun, that is capable of both removing chips and debris from blind holes and also vacuuming it away simultaneously.
This addresses the problem of dislodged chips being caught elsewhere on the parts. Fortunately, EXAIR offers an unconditional 30-day guarantee for all stock products. They were able to return the previously purchased gun and apply the credit towards the purchase of the Deep Hole Vac-u-Gun system.
The Deep Hole Vac-u-Gun is a low-cost solution to quickly remove chips and contaminants from grooves, containers, and drilled holes. In applications where simply blowing the debris out of the hole isn’t suitable, simply position the Deep Hole Vac-u-Gun over the hole and press the trigger. A small blow tube (3) dislodges and lifts the chips while the large suction tube (5) vacuums them away. The operator is then protected from flying debris since the contaminants are then contained within the suction tube and directed into a filter bag or other container with the included vacuum hose.
Sometimes we don’t always get it right on the first try. But, with the ability to take advantage of the 30-day guarantee we’ll make sure to get the best product to you for your application. With same day shipments with orders received by 3:00 ET for stock products, EXAIR can get a solution out to you quickly!
Vacuum cleaners…most of us think of the electric-powered devices that we clean our carpets at home with. The idea of utilizing vacuum in cleaning applications, however, predates the widespread introduction of electric power by a couple of decades. The original idea was to marry a manual vacuum generating device to a carpet sweeper. These had been around for some time, and they’re still seen today: the beater brush turns as the sweeper is pushed across the floor; it picks up dirt in the brush bristles, and deposits it in an internal receptacle. You’ve probably seen them used in restaurants to tidy up small messes on the floor, in lieu of dragging out the noisy vacuum cleaner while folks are eating.
Anyway, these first vacuum cleaners relied on a bellows, piston cylinder, or other such device that was operated by hand, foot – or, according to one source, a rocking chair – to generate a vacuum. Since it took one person to operate the vacuum generating part, and another to push the sweeper, they weren’t very popular at a time when folks were generally looking for labor SAVING products.
The proliferation of electric power around the turn of the 19th/20th century brought about electric vacuum cleaners. Most homes have one…including the ‘shop vac’ in my garage, my home actually has three. These are great for home use; many have long cords that allow you to clean the floors in adjacent rooms without unplugging & re-plugging, and most come with a convenient set of tools for baseboards, furniture, HVAC vents, etc. For carpet & upholstery, they can’t be beat.
In industrial settings, though, the electric-powered models can find themselves at a disadvantage. The impellers can clog or break, and the electric motors will, in time, burn out. If used in wet environments, great care must be used (as with any electric products) or there can be a very real shock hazard.
EXAIR Industrial Housekeeping Products offer a solution to all of these issues. With no moving parts or electric motors, they are extremely reliable. If you supply them with clean air, they can run darn near indefinitely, maintenance free. And no electric power means no shock hazard.
We have a variety of products to meet most any need. Our Chip Vacs and Heavy Duty Dry Vacs are made for dry material cleanup. They install (in minutes) on an open top drum, and are available with a variety of accessories…tools, drum dollies, tool holders…even the drum itself if you need one. The Chip Vac is specified for most ‘general purpose’ jobs; the Heavy Duty Dry Vac is more powerful, and abrasion resistant, for more aggressive needs. Both exhaust the vacuum air flow through a Filter Bag to contain the particulate in the drum.
The Heavy Duty HEPA Vac features the same high power and rugged construction as the Heavy Duty Dry Vac, but replaces the Filter Bag with a HEPA (High Efficiency Particulate Air) Filter for maximum dust containment. These are used where critical dust removal, mold & allergen containment, or trapping airborne irritants are called for.
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 Reversible Drum Vac is also at the heart of our popular and award-winning 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.
Speaking of two-way operation, the EXAIR Vac-u-Gun is both a vacuum AND blow gun…simply reverse the orientation of the nozzle insert to reverse the operation:
The Vac-u-Gun is an efficient, quiet, and versatile tool with numerous applications, from vacuuming sawdust or shavings, to conveying small parts or pellets, to blowing off chips, water, coolant, or scrap. And, just in time for Spring Cleaning season, we’re letting you find out just how handy it is, for free – by including one with any qualifying Industrial Vacuum purchase, now through April 30, 2019.
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?
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!
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.
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.
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.
What is the Vac-u-Gun? It is a low cost solution to many types of cleaning operations within an industrial setting. The Vac-u-Gun is a vacuum gun, a blow gun, and a transfer tool, all-in-one! It is lightweight, easy to use, has durable die cast construction, and best of all, no moving parts to wear out. Simply hook up to a compressed air hose, and get to work.
The Vac-u-Gun contains a nozzle insert that dictates the direction of air flow and operation. By simply unscrewing the the cap, reversing the orientation of the nozzle insert, and re-installing the cap, the gun is changed from a vacuum device to a blowoff device, and vice-versa.
The Vac-u-Gun can be used in three modes- Vacuum, Transfer and Blowoff-
Vacuum Mode – Vacuum shavings, absorbents, sawdust, or spills into a reusable bag, or into a receptacle via the vacuum hose. Why blow it off and the have to sweep it up later?
Transfer Mode – Transfer small parts, pellets, or trim over long distances, using the smooth bore vacuum hose.
Blowoff Mode – Blow chips, water, coolant, or scrap away from the work area. The large 1-1/4″ diameter outlet directs the air over a larger area in less time. The Vac-u-Gun uses less compressed air than an ordinary blow gun.
There are many advantages to a Vac-u-Gun, and some are:
Low cost, no moving parts/maintenance free, durable die cast construction, easy to switch form vacuum to blow mode, safe – no electricity, meets OSHA pressure requirements, lightweight and portable, versatile, and quiet.
Versatile! In just seconds, the Vac-u-Gun can transform from a powerful, handheld vacuum tool into an efficient blow gun or transfer tool for lightweight materials. Each Vac-u-Gun System comes with the attachments needed to suit numerous industrial applications.
Three (3) Vac-u-Gun System options are available and shown below-
All of the Systems include the Vac-u-Gun, brush, crevice tool, skimmer tool and (2) extension wands.
The Model 6192 Collection System also includes the reusable bag with clamp for debris collection.
The Model 6292 Transfer System also includes the vacuum hose, for transferring the debris to a collection point.
The Model 6392 All Purpose System also includes both the reusable bag and clamp and the transfer hose, providing the most versatility of all.

Inexpensive air guns can be picked up just about anywhere, and you generally get what you pay for. Most will be very noisy and waste lots of compressed air. And many will be unsafe, violating two of OSHA’s standards put in place to protect worker safety. The first is Standard 29 CFR 1910.95(a) which sets limits to the maximum noise exposure, and the second is Standard 29 CFR 1910.242(b) which says that the nozzle cannot be dead-ended, or exceed a 30 PSIG pressure limit.
These guns may seem like a perfect fit for a handheld blowoff application. The truth is, the cost saved up front will easily be paid throughout the cost of ownership. This is due to the lack of an engineered nozzle which meets and exceeds the OSHA standards mentioned above. The “cheap” guns often have a cross drilled hole to meet or exceed the OSHA standard for dead-end pressure. While this may be true, it causes a large wind sheer which escalates noise levels to well over the allowable noise level exposure set by OSHA. These tips sometimes offer large force outputs because they are equivalent to an open pipe. We have publicized numerous times about how an open pipe blow off does not permit pressure to be utilized all the way to the point of blowoff, and is also a waste of energy.
In order to determine how much compressed air your current blow guns utilize, the level of noise they product, and the sound level they produce, consider taking advantage of the EXAIR Efficiency Lab. The Efficiency Lab is a free service that you can read more about here.
An EXAIR Safety Air Gun is engineered and designed to comply both of the OSHA standards mentioned above, ensuring safe operation for company personnel. On top of the safety designed into the guns, we also ensure all of our guns are efficient by offering only engineered nozzles on them.
EXAIR offers (4) types of Safety Air Guns – the VariBlast, the Soft Grip, the Heavy Duty, and the Super Blast. Each type of Safety Air Gun is offered with a plethora of nozzles, as well as varying length extensions, with or without the Chip Shield.
We invite you to try out an EXAIR Safety Air Gun, and get the free 1″ Wide Flat Super Air Nozzle as a bonus. Click here for more details about this special promotional offer.
Now through the end of May, EXAIR is running a promotion on the Industrial Housekeeping Products that includes a FREE Vac-U-Gun with any purchase of an Industrial Housekeeping Vacuum System. EXAIR’s Vac-U-Gun is a low-cost solution to a wide variety of industrial housekeeping problems. The Vac-U-Gun has a durable die cast construction and no moving parts to replace or wear out.
In addition to being easy to use, the Vac-U-Gun is also more efficient than ordinary blow guns. By injecting a small amount of compressed air through directed nozzles, a vacuum is then produced on one end and a high output flow on the other. The amplified outlet flow through the Vac-U-Gun is 12 times the compressed air consumption of the gun.
The Vac-U-Gun is capable of both vacuuming material, as well as being operated as a blow gun. In vacuum mode, the work surfaces can be easily cleaned by vacuuming the debris away rather than blowing it off of the surface. Rather than simply moving the material around the shop floor, it can be contained and transferred to a waste receptacle using the 10’ vacuum hose, or straight into the filter bag.
Switching from vacuum mode to blow mode can be achieved in just a matter of seconds. To change the Vac-U-Gun from vacuum to blow mode, simply remove the threaded cap and change the orientation of the generator inside. Since the Vac-U-Gun has a large 1-1/4” diameter air outlet, it covers much more surface area in less time compared to traditional air guns. This can help to reduce the time needed for a variety of different blowing, cooling, or drying applications. Due to the nature in which the Vac-U-Gun entrains ambient air, it allows for more force and flow through the gun at a minimal compressed air consumption.
The Vac-U-Gun system is available by itself, or in one of three different kits. It can be used with or without the 10’ (3m) vacuum hose or the filter bag. Various vacuum accessories are included in the kits to accommodate a variety of different materials and applications. If you’re looking for a versatile gun that can help boost productivity in a number of applications within your facility, look no further than the Vac-U-Gun.
From now through May 31, 2018, 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.
When choosing one of our vacuums, selection can be simplified depending on what type of media you are needing to pickup. Our systems are going 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.
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.
All of these products are In-Stock, Ready To Ship.
