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-

HEPA Vac Improves Cleaning Process AND Keeps Operators Safe!

On a recent visit with our Hungarian Distributor, I had the pleasure of visiting an automotive leather manufacturing plant. They process and cut to order a wide variety of different styles of leather used in the manufacturing of European automobiles. In one of their machines, a grinding process is performed that smooths out the cut edges of the material before they’re stitched together.

The grinding process itself is self-contained within the machine, but the significant amount of leather dust created needs to be periodically cleaned out. If not, it ends up accumulating on some of the internal components and increasing the downtime and maintenance required on the machine. Due to this, they implemented a 2x per shift cleaning operation.

The machine has several tight spaces inside where the dust accumulates. They’d shut off the machine and blow out the dust. Then, sweep up all of the dust into a dustpan and dump it in the trash. This entire process took approximately 30 minutes each time for 1-hr/shift. With three shifts operating 24/7, that’s 3-hrs/day of lost production time for this particular cleaning process, still less than what they were experiencing as a result of the machine downtime when they weren’t regularly cleaning it.

However, the primary concern of theirs was that they were now blowing dust all over the shop causing a potential health hazard to their operators. They wanted a solution that would allow them to clean the machine, without presenting an additional hazard. We tested with a Mini Chip Vac first, but the dust was a bit too fine and was still passing through the filter bag.

For fine dusts such as this, the Heavy Duty HEPA Vac is the more suitable option. After testing the Heavy Duty HEPA Vac, it was clear that this was the solution they were hoping for. The high-powered vacuum made quick work of the dust inside, while keeping it contained inside of the drum by the HEPA filter.

They still need to stop and clean the machine out 2x/shift, but now the process only took 10 minutes. They reduced their overall downtime on this machine per day by 2/3 to just 1hr, while keeping their operators safe. While this wasn’t the reason for looking at new solutions, it was definitely an added benefit. If you’re looking for a maintenance-free vacuum system for cleaning up in your facility, EXAIR has a wide range of Industrial Housekeeping solutions available from stock.

Porous and Non-Porous E-Vac Vacuum Generators

Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’s E-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.

The Low Vacuum Generators are ideal for ‘porous’ types of applications.  When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.

The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Compressed Air Vacuums and Their Advantages Over Electric Vacuums

EXAIR‘s line of Industrial Housekeeping Products consist of liquid and dry vacuums that utilize compressed air to operate. They do not have loud electric motors which most ‘all purpose’ electric vacuums rely on.  In industrial settings with harsh conditions and rugged use, EXAIR’s Industrial Housekeeping Products are better suited for the everyday wear and tear of typical manufacturing, commercial and construction environments.

When you look at EXAIR vacuums, you’ll notice there is not an electrical cord.  Because the EXAIR Industrial Housekeeping Products utilize compressed air for operation. This means they do not have the same maintenance issues of an electric motor which breakdown and fail when dirt, dust and temperature take their normal toll on moving parts. With EXAIR vacuums there are no moving parts: no motors to burn up, no bearings to wear out, and no impellers to clog in the vacuum units. They also run quieter than a typical electric vacuum.

They are maintenance free, just supply clean and filtered air, and they can operate for many, many years.

 

EXAIR’s liquid vacuums, there is a built in pressure/vacuum relief device and auto safety shut-off to prevent over-filling.

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 heart of our popular 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.

EXAIR’s dry vacuums provide many pickup and filtration options. They withstand harsh environments, have many filtration and power options and run quieter than electric vacuums.

The EXAIR Chip Vac and Heavy Duty Dry Vac is a powerful industrial vacuum for use on wet or dry chips. Both are for use with 30, 55, or 110 gallon drums, and the Chip Vac can also be used on a 5 gallon drum. 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.

The Chip Vac is also 50% quieter than a comparable electric vacuum at only 77 dBA!!
