Campbell Hausfeld 5Z185B Air Compressor Pump

The Campbell Hausfeld 5Z185B air compressor pump is a cast-iron, oil-lubricated single‑stage pump designed as a stationary replacement for Campbell Hausfeld, Sears, and SpeedAire systems. It is listed in the 5Z185 family (also referenced as 5Z185A) and is associated with the VT 2Z630 designation, a combination commonly found on older oil‑bath Campbell Hausfeld units. The pump features a 3-inch bore and is built for durability in continuous‑use applications, with rebuild options such as gasket kit 01B509 to refresh seals and joints. As a stationary, oil‑bath pump, it is intended for mounting on a fixed frame and is representative of the pump assemblies used in classic Campbell Hausfeld and SpeedAire equipment.
