The Allegro Personal Air Cooler, a bestseller, is great for anyone working in hot environments and adjusts the air flow from high pressure air sources as low as 25 degrees colder than ambient air for an improved working environment. This product provides a low cost solution to respiratory cooling needs. Requires air pressure range of 55-85 psig. Includes belt and Hansen fitting. Connects to all Allegro High Pressure Hoods and Masks.
Vortex Tubes are an effective, low cost solution to respiratory cooling needs. With no moving parts, a vortex tube spins compressed air to separate the air into cold and hot air streams by forcing the compressed air through a generation chamber which spins the air centrifugally along the inner walls at a high rate of speed toward the control valve. A fraction of the hot air is discharged at the control valve. The remainder of the slower air stream is forced to counter-flow up through the center of the high-speed air stream, giving up heat, through the center of the generation chamber finally exiting through the opposite end as extremely cold air.
