The EXAIR VariBlast Precision Safety Air Guns

Published on by Brian FarnoLeave a comment

Handheld air guns are something that you can find in nearly any and all manufacturing facilities that have compressed air within them. Suppose they are not at every operator station because the machines don’t require compressed air. In that case, they are generally found at the very least within the maintenance department where they are continually keeping the facility functioning.

Don’t let this happen to your air gun…use an EXAIR Precision Safety Air Gun with a quiet, efficient Super Air Nozzle instead.

These handheld guns are easily overlooked for being safe and efficient for the operators to use. Often, the cheapest gun possible is also the most costly regarding ownership and operation. These are just a few of the reasons EXAIR designed the VariBlast Precision Safety Air Gun.

The ergonomic design fits well in any sized hand and the long trigger makes for easy use with up to the four-finger engagement. The integrated loop allows the tool to easily hang on a tether or hook near an operator station. The optional Chip Shield adds additional protection for the operator and can be adjusted to any location along the extension. The extension pipe is offered in three different lengths, 6″ 12″, or 20″ overall length. Each one of these components is also field replaceable in the event one becomes damaged.

There are three different models of Super Air Nozzle available at the end of the extension in two separate materials. You can purchase the Atto, Pico, or Nano Super Air Nozzle in either stainless steel or PEEK thermoplastic for more sensitive applications. These nozzles coupled with our engineered valve design permit the user to vary the amount of air coming out of the gun by pulling the trigger to a higher flow or pulling it slightly and letting less volume of air through.

If you want to discuss whether the current air gun you use meets or exceeds OSHA standards and how much air it may use versus what an EXAIR VariBlast Precision can do for you, please contact an Application Engineer today.

Spring Cleaning & Free STUFF

Published on by Brian FarnoLeave a comment

That’s right in case you didn’t notice, Spring is upon us and that generally means a good amount of cleaning is coming into your lives. I have been cleaning up the yard, garage, patio, shed, and even basement just trying to get everything for being outside more and making sure all of my equipment is ready to go for the warmer weather. The good news for you is that EXAIR is making Spring cleaning even better in your industrial setting with our new promo.

Right now, purchase any EXAIR Industrial Housekeeping System and receive a FREE Vac-U-Gun! The best part about these pneumatically driving vacuums is that there are no carburetors to clean them, and no batteries to charge, just plug them into your shop air and go. Whether you need a liquid vacuum, dry vacuum, or wet/dry vacuum, we have a product that will fit your need and if you aren’t sure, we have a dedicated team of Application Engineers here to help.

EXAIR's new Chip Trapper
EXAIR’s new Chip Trapper

For liquid vacuums, we offer the Chip Trapper which permits you to filter solids from the liquid being sucked up, then pump the filtered liquid right back out of the 30, 55, or 110-gallon drum. Filter bags are available in 1, 5, 25, 50, 100, and 200-micron ratings. The High Lift Chip Trapper is the same principle just near double the vacuum level so you can suck more viscous liquid or sub-grade sumps clean.

The Reversible Drum Vac and High Lift Reversible Drum Vac use the same vacuum generators as their Chip Trapper counterparts and give you the ability to use a 5, 30, 55, or 110-gallon drum to empty a sump and pump all the contents into another container. (5 gallon is only available in the standard Reversible Drum Vac, no High Lift version.) I know I’ve told the story before, I used to utilize a Reversible Drum Vac when I was in the metal cutting industry. As I was setting up trade show booths full of metal cutting machines, I would hook my RDV up to the drums and pump machines full of premixed coolant, then at the end of the show, I would suck all the sumps dry and be waiting for load out while other booths would still be fooling around with an electric vacuum or waiting on another service that had a large tow-behind system.

(Left to right) Chip Vac, Heavy Duty Dry Vac, Heavy Duty HEPA Vac

When it comes to dry vacuums, the Chip Vac, Heavy Duty Dry Vac, and Heavy Duty HEPA Vac are all ideal due to their no moving parts and simplistic design to get the job done. Whether it is a machine shop cleaning up chads and chips, a grinding shop cleaning up fines, or even a general facility cleaning dirt, debris, and scraps from the floor, these vacuums hook straight to shop air and are ready to work. The filters can all be cleaned and reused or replaced if you chose. They again, fit standard drum sizes and can even include the drum with the purchase.

For critical dust containment, the HEPA EasySwitch Wet-Dry Vac System is your durable, reliable, compressed air operated solution!

Lastly, our EasySwitch Wet/Dry Vac is the only vacuum I know of on the market that can be converted from wet to dry in less than 10 seconds and still have no internal moving parts. The unit is honestly a game changer compared to the electric equivalent and doesn’t have a motor or impeller to wear out.

Then, to top any purchase of those units off, the current promotion enables end users in the US or Canada to receive a Vac-U-Gun for free. This is a tool that many utilize to blow down a workstation, then turn around and vacuum everything up off the floor.

If you would like to discuss any of these systems more in-depth, since I stayed at a high-level explanation, please feel free to contact an Application Engineer.

Spot Cooling, Cold Gun Promotion

Published on by Jordan T ShouseLeave a comment

Like many companies, here at EXAIR we generally always have a promotional offering.  These rotate throughout the months and this month is no different.  The current offering involves the EXAIR Cold Gun Aircoolant Systems.

These spot cooling systems help to reduce cutting fluid use, increase production speeds, increase tool life, and has helped more customers than I know.  One customer in particular is a maintenance worker from a welded tube manufacturer.  This facility had very little amount of downtime permitted due to the high efficiency and high volume of orders.  When a machine went down the maintenance team went in like a trauma team to determine the cause of failure and get it fixed to get the line back up and running. One of the biggest problems they would have is when they would have to dry machine a quick part to get the machine back up and running, this would either ruin tools or they would have to slow down the machining time to get the surface finish and dimensions they truly needed.  After talking with us the team ordered a Single Point Cold Gun Aircoolant System as these parts were generally small enough to tackle with the single cold outlet (larger parts benefit from the dual point hose kit).

They received the spot cooler system in and sure enough a machine went down.  The crew went to work and once the broken part was located they got to work on their lathe trying to make a new piece.  The Cold Gun held itself straight to the headstock thanks to the integrated magnet and the flexible single point hose kit routed the cold air straight to the cutting insert point.  They didn’t have to fill up the liquid tank or setup the mist system on the lathe, they simply turned on the compressed air and let the lathe do the work.  They were able to take what had recently been around a three hour machine job with heavy wear on tooling to a two hour job, no finish pass was needed on the part, and their tools weren’t completely spent by the end of the job.

They got the part back into the machine, made adjustments, and then went to work getting the machine back into production.

Right now, if you would like to try out a Cold Gun Aircoolant System you can order before 12/31/21 and you will receive a free Dual Point Hose Kit with your qualified purchase.

Carburetors and Venturi Tubes: Thank You Giovanni Battista Venturi

Published on by Brian FarnoLeave a comment

I know it has been a little while since I blogged about something with a motor so it should be no surprise that this one ties to something with a combustion chamber. This all starts with an Italian physicist, Giovanni Battista Venturi. His career was as a historian of science and a professor at the University of Modena. He gave Leonardo da Vinci’s creations a different perspective by crediting da Vinci to be a scientist with many of his creations rather than just an amazing artist. He then began to study fluid flow through tubes. This study became known as the Venturi Tube. The first patents in 1888 came to fruition long after Giovanni passed away. So what was this Venturi effect and how does it tie in to carburetors let alone compressed air?

The illustration below showcases the Venturi effect of a fluid within a pipe that has a constriction. The principle states that a fluid’s velocity must increase as it passes through a constricted pipe. As this occurs, the velocity increases while the static pressure decreases. The pressure drop that accompanies the increase in velocity is fundamental to the laws of physics. This is another principle we like to discuss known as Bernoulli’s principle.

1 – Venturi

Some of the first patents using Venturi’s began to appear in 1888. One of the key inventors for this was Karl Benz who founded Mercedes. This is how the Venturi principle ties into combustion engines for those that do not know the history. This patent is one of many that came out referencing the Venturi principle and carburetors. The carburetors can vary considerably in the complexity of their design. Many of the units all have a pipe that narrows in the center and expands back out, thus causing the pressure to fall and the velocity to increase. Yes, I just described a Venturi, this effect is what causes the fuel to be drawn into the carburetor. The higher velocity on the input (due to this narrowing restriction) results in higher volumes of fuel which results in higher engine rpms. The image below showcases Benz’s first patent using the Venturi.

2 – Venturi Patent

While carburetors slowly disappear and now can mainly be found in small engines such as weed eaters, lawn mowers, and leaf blowers, the Venturi principle continues to be found in industry and other items. Needless to say, I think Giovanni Battista Venturi would be proud of his findings and understanding how monumental they have been for technological advancements. For this, we will recognize the upcoming day of his passing 199 years ago on April 24, 1822.
