The Prevost self-retracting compressed air hose reel ensures optimum safety during use and when storing the hose after use. The easy-to-operate ratchet automatically locks the hose at the desired length, and the ceiling or wall-mounting bracket swings 180 degrees. Tools are quickly and safely connected with a prevoS1 quick release safety coupling. After the ratchet is released by the operator, a control system in the reel returns the hose gradually. The operator can safely let go of the hose thanks to a brake system. Other features include a maximum pressure of 174 psi and a maximum temperature of 158 degrees F. This unit is constructed of epoxy-coated steel and stainless steel.
