As the pressure drops from 100 psi down to atmosphere through the tool or valve the compressed air, which is always at 100% humidity, super cools rapidly and can freeze up the equipment. Polar-Lube technology replaces regular lubricant in the FRL unit and prevents this from occurring. In fact it will protect airlines down to -60˚F. Simply adding it to a frozen tool inlet will unfreeze the tool. It lubricates and will not effect O-rings, seals, rotor blades, bowls or hoses and is compatible with all manufactures drop, mist or automatic lubricators. www.roessel.com
