EXAIR Pneumatic Liquid Vacuums

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

Reversible Drum Vac with spill recovery kit!
EXAIR liquid type vacuums, like the Reversible Drum Vac, the High Lift Reversible Drum Vac, and the Chip Trappers are reliable, versatile and easy to use. Installing onto an any closed head, 30, 55, or 110 gallon drum creates a high powered vacuum.  It can fill a 55 gallon drum in less than 2 minutes.  Then, with the turn of a knob, the the same pump quickly empties the drum. Useful for refilling coolant sumps, vacuuming floor spills, or transferring contaminated liquids to filtration tanks in minutes.  Flow rate can be controlled with the knob.

The Chip Trapper has an internal filtration system to separate the chips from the coolant, allowing for disposal of the solids, and for pumping of the clean coolant back into the sump.
EXAIR Chip Trapper
When you look at the vacuums, you’ll notice there is not an electrical cord.  Because the EXAIR Industrial Housekeeping Products utilize compressed air for operation, they do not have the same issues with wear, breakdown and failures as electrical type vacuums. There are no moving parts in the vacuum units to wear out or break.  They are maintenance free, just supply clean, dry air, and they will operate for a long time. For the the liquid type systems, there is a built in pressure/vacuum relief device and auto safety shut-off to prevent overfilling.

There are no motors and bearings to wear out and no impellers to clog.  The Chip Vac is 50% quieter than a comparable electric vacuum.  Safety is a top priority, and the use of the unit on wet floors and spills is not an issue when electricity is not involved.

Back Blow Air Nozzles Clean Out Pipe, Tubes and Holes

Round SS Tubes

A metal fabricator used a cutting machine to cut different sizes and shapes of stainless steel tubing.  The process was automated and the machine would cut two tubes at a time.  After the cutting operation, the machine would deposit the tubes into a nearby bin.  The operator would then stack the tubes in a wooden container as shown above.  Before the tubes could be transported to another department, the operator would have to clean the inside of each tube.  The current method was to attach a rag to the end of a rod and pushed it inside the tube to remove any coolant and chips that remained from the cutting operation.  Of course, the ability to clean thoroughly with a rag is reduced greatly after a short time of use.  The cleaning process was very time consuming, and when the rag was not changed in a timely manner it did not clean effectively.  The inside of the tubes would get marred from the excess chips that remained on the rag.  This would visually affect the surface finish of the stainless steel.  They emailed me the application detail as they were looking for a non-contact way to clean the inside of the tubes.

The first question from the customer was if we could customize our air nozzles to clean the different diameters and shapes that they were cutting.  EXAIR has made special air nozzles to accommodate unique applications, but I wanted to first make sure that EXAIR did not have a manufactured nozzle in stock to fit this application.  I requested the dimensional information, and the customer sent me the sizes and shapes of the tubes that were ran through their cutting machine.  (Reference Table 1 below).

EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels.  They can range from internal diameters from ¼” (6.3mm) to 16” (406mm).  The 360o rear airflow pattern can “wipe” the entire internal surface clean and can remove coolant, chips, and debris.  In reviewing the dimensions from Table 1 above, I was able to recommend just one Back Blow Air Nozzle for all the tubes; even the square and rectangular ones.  It was model 1006SS Back Blow Air Nozzle.  This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from 22mm to 102mm, and it was perfect for all of these tubes.

Soft Grip Safety Air Gun w/ Back Blow Air Nozzle

The customer indicated to me that the tubes were all cut to identical lengths at 550 mm (21.7”).  Being that this was a manual operation, I suggested the Back Blow Air Nozzle with our Soft Grip Safety Air Gun.  This ergonomically designed Safety Air Gun is designed for hours of use without fatigue.  In combination with the nozzle, we are able to add extensions and chip shields.  With extensions, EXAIR has a range of lengths from 6” (152mm) to 72” (1,829mm).  With the designated length above, I recommended the model 1206SS-24-CS which has the Soft Grip Safety Air Gun, the model 1006SS Back Blow Air Nozzle, a 24” (610mm) extension, and a chip shield.

The configuration allowed for the operator to reach through the tube to clean with only a one-time pass.  The CS designation is for a chip shield which will protect the operator from any excess debris and coolant.  With the model 1206SS-24-CS, the operator could now pick up a tube, use the Soft-Grip Back Blow Safety Air Gun to remove the debris and coolant from within the round tubes, square tubes and rectangle tubes.  Also, they did not have to worry about changing the rags when it got dirty.  What an amazing purchase for this company, as they increased the speed of the cleaning operation by 70% without affecting the inside finish of the stainless-steel tubes.

If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles.  EXAIR can attach these nozzles on our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use manual operations.  For this customer above, they were glad that they contacted EXAIR about their application.  If you require more details, you can share your application with an Application Engineer at EXAIR.  We will be happy to help.

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-

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.
