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

Published on by Leave a comment

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-

Deep Hole Vac-u-Gun Systems

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

Published on by exaircorpLeave a comment

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.

Deep Hole Vac-u-Gun Cleans Printed Circuit Board (PCB).

Published on by exaircorpLeave a comment

An electronics component manufacturer produces high quality, flexible and rigid printed circuit boards (PCB’s) for a wide range of applications.. They were looking for a more reliable solution to clean dust particles from their DIMM or Dual In-Line Memory Module sockets on PCB’s. This particular process is very critical as any dust or debris that remains in the socket, will cause them to fail inspection and the need to be reworked or ultimately considered lost product and remanufactured.

Example of a circuit board

They were currently using compressed air blowing through a small open tube to blow out the sockets. While this was successful in some cases, in others they were seeing the blown particulate settle in another location on the board which would lead to the conditions mentioned above. Their thinking was to have a system where they could blow out the small areas on the circuits, while also having a way to vacuum or carry the particulate away from the area. They were looking into a traditional vacuum hood system but these units tend to be for larger industrial type applications where their process was a much smaller scale ranging from 50mm up to 200mm. Another concern was with the boards being so small and lightweight , the vacuum system may try to vacuum the PCB’s themselves.

After discussing the details of the application, I recommended they use our Deep Hole Vac-u-Gun in the application. The Deep Hole Vac-u-Gun features a small blow tube that upon squeezing the trigger, provides a burst of air to lift or loosen dust or particulate trapped in small holes or cavities. The unit simultaneously provides vacuum that is able to collect the released fines and carry them away from the area, removing the potential for further contamination.
