OEM AIRMAX 11.4751

Genuine Airmax Pressure Switch 11.4751 — 120/150 PSI, 3/8 in. NPT 4-Port

Genuine Airmax pressure switch and control manifold, OEM part number 11.4751, from the Airmax Series 11 line. It is the complete control head for a reciprocating compressor: the switch cuts the motor at 150 PSI and restarts at 120 PSI, the built-in unloader bleeds head pressure so the motor restarts against no load, and the 4-port manifold takes the gauge, safety valve and discharge line. In stock in Canada with fast Eastern Canada shipping.
