Cold Gun Aircoolant System™: Overview

EXAIR Cold Gun Promotion

Many machining companies like to use coolant to flood their parts for drilling and milling operations.  But what if there was an alternative way?  EXAIR has an interesting technique by using cold air instead of coolant.  This would help save time by eliminating cleaning and drying of parts as well as reducing coolant waste.  EXAIR calls this product our Cold Gun Aircoolant System™.

How the Cold Gun Works

The Cold Gun Aircoolant System uses a Vortex Tube to produce a cold air stream at 50oF (28oC) below supply air temperature.  Heat is one of the major causes for dulling and premature failures for tools, and by blowing cold air, it will reduce the heat buildup in tools while also removing the chips from the surface.  The EXAIR Cold Guns are very compact, portable, and easy to use.  Just attach compressed air to the unit, and it will produce cold air.  Since they do not have any moving parts, Freon, or electricity to operate, it is maintenance-free and long-lasting.  And, EXAIR offers a 5 year “Built To Last” warranty against defects in workmanship and materials.  These systems will extend tool life, improve tolerance control, and increase production rates by replacing coolant during milling, cutting, and drilling operations.

The benefits of using the Cold Gun Aircoolant System extends beyond reducing tool wear, finishing with dry parts, and surface smearing.  It can be used in applications where liquid coolant cannot be used.  This would include wood products, MDF, and plastics.  As insulators, cutting tools will get extremely hot as the material will not remove any heat like with metal chips.  Thus, machining can soften, gall, or burn the surface of the material; allowing only slow speeds for operations.  The cold air from the Cold Gun can keep the tools sharp and the materials hard and firm.  With plastic materials, this is very beneficial as it will keep the plastic rigid for tight tolerance machining.  If burnishing or scoring is occurring, the Cold Gun Aircoolant Systems can help to improve the surface finish of your product.  Other applications would include surface grinders, laser cutters, hot melt setting, and band saws.  The Cold Gun Aircoolant Systems are a low-cost solution that can do a lot of great things to improve processes.

Cold Gun Aircoolant Systems

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.  The four models that EXAIR stocks are in the photo above.

EXAIR is running a promotional offer on the Cold Gun Aircoolant Systems.  From now until the end of yr2019; if you buy a Single Point Cold Gun System or a Single Point High Power Cold Gun System; model W5215 and model W5230 respectively, we will include a free model 5902 Dual Point Hose Kit, a $39.00 value, with your system.  And as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out.  If you have an application that you believe would be better served with an EXAIR Cold Gun Aircoolant System™, contact an Application Engineer.  And take advantage of our promotional offering by receiving a FREE Dual Point Hose Kit.

Promos, Freebies, and Some Amazing Products

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 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 were in like a trauma team to determine the cause of failure and get it remedied 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 smaller shafts or machine dogs.

They received the system in and sure enough a machine went down.  The crew went to work and once the part needed was found 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 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 12/31/2019 and use the link to order through our promotion in order to receive a free Dual Point Hose Kit with your qualified purchase.
