EXAIR VariBlast® Safety Air Gun wins the Silver Award by Plant Engineering

VariBlast Safety Air Gun

EXAIR has been manufacturing Intelligent Compressed Air Products since 1983.  In that time, we have engineered many new products for new and existing markets that had better efficiency, versatility, and effectiveness.  To gauge how a new product is received by your peers, we like to send them to different committees for evaluations.  This year, we sent our VariBlast Safety Air Gun to Plant Engineering to compete against other new products in the manufacturing and non-manufacturing industries.  In the compressed air category, the EXAIR VariBlast Safety Air Gun won the Silver Award at the Plant Engineering Product of the Year event.

 

How was EXAIR able to achieve such a prestigious award?  Well, let me tell you how our newest safety air gun was able to receive this award.  I will discuss the features and benefits with the VariBlast Safety Air Guns, so you can decide for yourself.

To start, the unique feature that sets the VariBlast apart from other small air guns is the force variability.  Unlike the “all or nothing” blowing forces with most air guns, this valve is designed to control the opening to allow for a variable force with the same nozzle.  This will help you to not “overuse”  your compressed air blowing. The VariBlast Safety Air Gun is made from a durable cast aluminum construction for tough industrial use.  It has a rugged ergonomic grip with a user-friendly trigger.  The compressed air inlets are located in two different positions to best fit your application.  They have an easy storage handle to hang the Safety Air Gun nearby.  In addition to the VariBlast Safety Air Gun, EXAIR has options to enhance the features and benefits.  Here is a list of them:

Model 1103 – Super Air Nozzle

Air Nozzles:

Air Nozzles can make or break an air gun in safe, efficient and effective use.  EXAIR Air Nozzles are OSHA compliant for noise and dead-end pressure.  We offer nine different air nozzles with the VariBlast Safety Air Gun; making it very effective for a wide range of applications.

Chip Shields:

OSHA 1910.242(b) requires chip guarding when compressed air is used for cleaning.  EXAIR offers Chip Shields with the VariBlast Safety Air Guns to meet this requirement.  They are made from a polycarbonate disc which is practically unbreakable.  It protects the operator from any blow back of shavings and coolant.  They come standard with a durable rubber grommet that squeezes onto the extensions and can be adjusted for maximize protection.

Extension Pipes:

For those far away targets and hard-to-reach areas, EXAIR offers aluminum extension pipes to attach to the VariBlast Safety Air Guns.  They can range from 6” (15 cm) to 72” (183 cm) in length.  This light-weight and durable material allows for easy handling when reaching high above your head or spanning across unsafe areas.  With the EXAIR air nozzles at the end, the blowing force is not sacrificed as the back pressure will create a high velocity air stream.

Coiled Hoses:

To get the proper amount of compressed air from the piping system to the VariBlast Safety Air Guns, EXAIR offers Coiled Hoses.  They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters).  They have swivel fittings to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking at the ends.  The coiled design makes it easy to reach around the work area and retract back to the substation.  This will help to keep the hose off the ground where potential dangers could occur.

Regulator and filter

Filter Separators/Regulators:

To improve the use of the VariBlast Safety Air Guns, EXAIR offers a series of filters and regulators.  The Filter Separators will remove dirty particles and liquid water from the compressed air that can affect the performance as well as contaminate the surface that you are cleaning.  The Regulators are used to control the amount of air pressure used by the VariBlast Safety Air Gun; making them even more efficient.  The idea for compressed air savings is to use the least amount of compressed air to do the job.  The combination of a filter and regulator will allow you to control the proper amount of clean dry air to be used.

Not all air guns are the same.  There should be a check list created prior to purchasing an air gun.  Is it safe, efficient, quiet, durable, ergonomic, and flexible?  The VariBlast Safety Air Guns meet every item on that list.  This is why the EXAIR VariBlast Safety Air Gun was awarded the Silver award by Plant Engineering.  If your current air gun does not meet these requirements, you may want to try the VariBlast Safety Air Gun.  You will not be disappointed.  If you are within the U.S. or Canada, we do offer a 30-day unconditional guarantee to try them out.

Industrial Vacuums For Most Any Cleanup Need

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.

Reversible Drum Vac Family

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.

Chip Trapper Systems come complete, ready to go, right out of the box.

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:

EXAIR’s Vac-u-Gun transforms in seconds from powerful vacuum to efficient blow gun.

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.

If you’d like to discuss a cleanup application, and how an EXAIR Industrial Housekeeping Product can suit your needs, give me a call.

Custom Products from EXAIR Meet Your Specifications

Since EXAIR manufactures and distributes our own products, we have the flexibility to provide custom products, special processing, unique packaging and more. If your process or specifications are something special, let us know and we will do our best to accommodate any special considerations you might need. Following is one example for a customer who purchases air guns.

Several months ago I received a call from a company that was looking for a specialized air gun.  This company was involved in the servicing of highly specialized measuring equipment and needed a safe, quiet, & efficient air gun that also had to be completely oil/contamination free.   This was to ensure no contamination would result from using the air gun on any of their equipment.  Ultimately this meant that every air gun component needed to be washed,  rinsed and dried to ensure there was no residual oils or dirt from manufacturing left on or in any component of the gun.

Our customer decided on the highly versatile Vari-Blast Compact Safety Air Gun with the award-winning Nano Super Air Nozzle, specifically models 1698SS and the 1698SS-6.  EXAIR presented a written process to the customer. This process explained how we would identify and manufacture their specific air gun in order to assure the customer that would receive a consistently clean air gun, every time.

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.
