Deep Hole Vac-u-Gun – Blow Chips Loose and Vacuum Them Away in One Step!

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?

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-slots’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.

The Deep Hole Vac-u-Gun = Dual Problem Solver

A little while back, I was contacted by a customer who was looking for a way to clean chips and debris out of tapped holes in an engine block. They were familiar with our products, having used them in several different areas in their plant, and had done some early research into our Air Nozzles.

They were considering using our small M4 Back Blow Air Nozzle in the process. The Back Blow Air Nozzles produce a 360° airflow that blows away from the end of the nozzle and in many cases, are the ideal solution for treating the inside diameter of hose, pipe, machined holes, etc. These unique nozzles, eliminate the concern of forcing particulate further down into a machined hole or the safety issue of blowing material out of the opposite end of an open tube or pipe.

EXAIR Back Blow Air Nozzles come in three sizes, for bores from 1/4″ to 16″ in diameter!

In this particular case, having the material blown out of the hole increased the risk of possible cross contamination somewhere else in the engine block so they were also thinking of incorporating some type of recovery system like our Chip Vac or one of our Line Vacs but were concerned with having to use two separate devices.

Once again, EXAIR has the perfect solution, the Deep Hole Vac-u-Gun. The Deep Hole Vac-u-Gun features a small blow tube (1/8″ OD) that provides a small blast of air to dislodge or loosen foreign material while simultaneously providing vacuum to carry the debris away.

If you have a similar application or would like to discuss how an EXAIR Intelligent Compressed Air Product can help solve a unique situation, contact an application engineer for assistance.

Back Blow Nozzles: When Blowing Forward Is Not An Option

Have you ever been in a situation where you need to blow debris or chips out of a pipe or a blind hole?   Maybe it is a pipe you are saw cutting and don’t want to push chips and debris further down the pipe line  You could be trying to clean out a pipe that has debris inside and and can’t push it further down the line because it could damage other system components.  Other customers cleaning out inside diameters of pipe cannot blow all the way out the other side of the pipe due to people being present on that end of the pipe and need to avoid harming them.

The Model 1006SS cleans metal shavings from inside a pipe.

This is where EXAIR has seen an opening in our product offering and we have filled the void yet again.  We currently offer two sizes of the EXAIR Back Blow Nozzle.   The 1/4″ NPT version, model 1006SS is made to clean out pipes from 7/8″ I.D. to 4″ I.D.   The 1″ NPT version, model 1008SS, is best suited for pipes from 2″ I.D. to 16″ I.D.
