Frost Free Cold Air Guns
Product Overview
The Frost Free Cold Air Gun eliminates the mess associated with condensation and frost arising from continuous use of a Cold Air Gun. A must–have for sensitive applications such as:
- Cutting, drilling or machining of paper products, wood products, fabrics or any product that is sensitive to water
- Machining of materials covered with oil or oil-based lubricants
Cold Air Guns use vortex tube technology and filtered compressed air to produce sub-freezing airas low as -30 deg F for numerous industrial spot cooling applications. With no moving parts to wear out, Cold Air Guns require no electricity, just a compressed air source.
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 increase 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. Cold Air Guns have adjustable temperature and flow settings; and some models have a frost free nozzle to eliminate mess from frost and condensation.
Benefits
- Increase dry machining speeds up to 36%
- Extend tool life by 50%
- Eliminates the mess, expense and safety concerns of using mist coolants
- Reduce waiting or normalization time by cooling parts faster
- Eliminate the potential for burning and scorching
- Avoid secondary parts cleaning after machining
- Reduce grinding wheel loading caused by overheating
- Airflow clears sawdust, shavings and dirt away from surface
Features
- Creates cold air up to 100 F deg (+ 56 C) below the inlet compressed air temperature
- Quiet operation; meets OSHA noise specifications
- Adjustable temperature and flow rate
- Highly reliable with no moving parts
- Low pressure outlet air
- Uses only compressed air – no Freon
- System includes a magnetic base and a 5 micron auto-drain compressed air filter
- Magnetic base allows for easy, close in positioning and easy portability
- Ergonomic trigger mechanism on the Cold Air Pistol
- Frost free nozzle eliminates mess from frost and condensation
