Air-Care Cobra-7 Air Duct Cleaning Machine (220v/50Hz) Relays & Fuses SV or W - whichThe Air Care Cobra 7 is a cable driven power brush system for cleaning air conditioning ductwork and dryer exhaust ducts. A 90 volt DC motor in a portable case spins a 10 metre flexible cable fitted with a self adjusting Flex E Bristle brush. The brush is fed into the duct, the operator controls speed and direction from a wireless remote, and the rotating bristles break the contaminant film off the duct wall so a negative air machine can carry it
