Multi-Point Spot Cooling in Tight Spaces

The Mini Cold Air Gun is engineered for applications where the standard Cold Air Gun is too large to fit, or where compressed air flow is limited. The Mini Cold Air Gun uses only 8 SCFM of compressed air and produces temperatures as low as 0 deg F. The Mini Cold Air Gun is available with a single nozzle or a dual point nozzle for multi-directional cooling.

Cold Air Guns utilize vortex tube technology and filtered compressed air to generate sub-freezing air as low as -30 deg F (-34 deg C) for various industrial spot cooling applications. With no moving parts to wear out, Cold Air Guns require no electricity at the target, just a compressed air source.

Cold Air Guns are predominantly used for cooling of metal parts, in the machining and repair of metals, plastics, wood, ceramics and other materials. Cold air machining performs better than mist coolants and considerably increases tool life and feed rates on dry machining operations. The efficient cooling from a Cold Air Gun can prevent heat-related parts growth while bettering parts tolerance and surface finish quality.

Benefits

  1. Improve dry machining speeds by up to 36%
  2. Prolong tool life by 50%
  3. Alleviates the mess, cost and safety issues of using mist coolants
  4. Lessen waiting or normalization time by cooling parts quicker
  5. Decrease the chances of burning and scorching
  6. Eliminate the need for secondary parts cleaning after machining
  7. Diminish grinding wheel loading caused by overheating

Features

  1. Produces cold air up to 70 F deg (21 C deg) below the intake compressed air temperature
  2. Quiet operation; meets OSHA noise specifications
  3. Highly reliable with no moving parts
  4. Low pressure outlet air
  5. Utilizes compressed air only– no Freon
  6. System comes with a magnetic base and a 5 micron auto-drain compressed air filter
  7. Magnetic base allows for easy, close in positioning and easy portability

Case Studies

Mini Cold Air Gun Keeps Blades Cool for Over 20 Years
Company Overview Joe Allen Knives is a one-man operation that makes pocket knives (also known as “folders” in the industry) Folder Knifeand Bowie and hunter’s knives. Mr. Allen entered the knife making business nearly 30 years ago by setting up a small shop in his basement. He made his first knife in his spare time while working at Snap-On Tools.

The Challenge Mr. Allen purchased a used surface grinder to grind the knife blades. He saw that the grinder did not have anything to contain the liquid coolant that is normally used in surface grinding applications. He did not want to deal with the mess of liquid coolant all over his equipment (not to mention the hassle of disposing of it) so he started looking for an alternate solution to replace the liquid coolant.

The Solution Over two decades ago, Joe saw an advertisement in an MSC catalog for the Vortec Mini Cold Air Gun and decided to give it a try. He purchased a small air compressor that would be able to supply air to the Mini Cold Air Gun and to the rest of his air powered tools in his new home shop. He decided on a compressor with a 40-gallon tank that would deliver 9 scfm of air at 90 psig. The Solution The Vortec Mini Cold Air Gun uses 8 scfm of compressed air to produce 4 cfm of cold air at 10 degrees F. This translates into 350 btuh of cooling. The cold air keeps the knife blades cool during grinding and prevents the steel from warping and discoloring. The cold air also blows the grinding dust away and prevents the grinding wheel from loading up too quickly. It eliminated the need for Joe to use liquid coolant and the mess and hassles associated with disposing of it and it continues to be his ideal solution 20 years later.

How the Mini Cold Air Gun Works Mini Cold Air Guns use vortex tube technology and filtered compressed air to produce sub-freezing air as low as 10 deg F for numerous industrial spot cooling applications. With no moving parts to wear out, Mini Cold Air Guns require no electricity at the target, just source of clean and dry compressed air.

Cold Air Guns are most often used for cooling of metal parts, in the machining and repair of metals, plastics, wood, ceramics and other materials. Cold air machining outperforms mist coolants and substantially increases tool life and feed rates on dry machining operations. The effective cooling from a Cold Air Gun can eliminate heat-related parts growth while improving parts tolerance and surface finish quality. The Mini Cold Air Gun is designed for applications where the standard Cold Air Gun is too large to fit, or where compressed air flow is limited. The Mini Cold Air Gun uses only 8 SCFM of compressed air and achieves temperatures as low as 10 deg F. The Mini Cold Air Gun is available with a single nozzle or a dual point nozzle for multi-directional cooling.
