OIL-FREE AIR ACTUATOR; OMAX #312827

Actuator Assembly, Air, On/Off Valve, Oil-Free. Assembly of the air actuator with the oil-free ring seal piston. Replacement for P/N 303509 and 301801. NOTE: The 301801 actuator has been replaced with 312827 oil free actuator (no oiling needed). When replacing any 301801 actuator with the newer oil free actuator, it is a requirement that the actuator on the opposite end (cutting head or dump valve) also be a 312827 for balanced operation speed.
