  • Respirator system with curved vortex tube
    Patent number: 10537756
    Abstract: A respirator system having a vortex tube with an arcuate hot leg. A respirator helmet has an inlet hose. A vortex tube with an arcuate hot leg and an inlet port is coupled to the respirator helmet. A compressed air source is coupled to the inlet port to supply air to the vortex tube in the range of 110 liter/minute (l/min) to 425 l/min and in the range of 40 pounds per square inch (psi) and 80 psi. This portable arrangement provides effective temperature control within the respirator system.
    Type: Grant

  • Curved vortex tube
    Patent number: 9599372
    Abstract: A vortex tube with an arcuate hot leg. A vortex tube include a vortex chamber couple to a first tube, a cold leg, to carry a cold air stream and a second tube, the hot leg, to cause the separation of hot and cold air. The hot leg bends in an arc to allow a longer and more efficient hot leg in reduced linear space.
