VORTEX TUBE: How it Works

(A) Compressed air, normally 80 to 100 PSIG (5.5 – 6.9 BAR) enters the pnuematic Vortex Tube through a standard NPTM inlet and tangentially through a generator into the vortex spin chamber.

(B) This air stream spinning at up to 1,000,000 RPM travels in one direction along the small (hot end) tube and then is forced back through the center of this outer vortex.

(C) The brass control valve on the hot end allows for quick n’ easy adjustment of the “cold fraction”; see specifications for what this means.

(D) As the center column travels towards the opposite end, it gives off kinetic energy in the form of heat to the outside stream of air and exits the vortex tube as cold air.
