Allegro High Pressure Heater w/ Belt, Vortex Style

Available - Usually ships in 1 - 2 days
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 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.

The air temperature controller adjusts the amount of air to the helmet and adjusts air temp 25 degrees F (-3.8 C) warmer than the ambient air for use in cold environments.

The respirator’s air source must be supplied at all times with clean breathable air, Grade D or better as defined by the Compressed Gas Association. (Commodity Specification G-7.1)
