I.E.E 26 Amp HD Pressure Switch for Air Compressors — 145-175 PSI, 4-Port, 0-200 PSI Gauge, 200 PSI Pop-Off Valve

Overview

Meet the I.E.E 26 Amp HD Pressure Switch, a four-port control valve designed for air compressors in demanding environments. Built to handle single-phase or three-phase power (110/230V), it combines a factory on/off setting of 145-175 psi with a 0-200 psi gauge and a 200 psi pop-off valve. This setup provides clear visibility of current pressure and a safety relief when limits are reached, helping your system respond quickly and predictably.

Durable design and precise control

The unit is UL Listed and CSA Certified, featuring a DPST switch and a rugged NEMA 1 enclosure. It supports a wide operating temperature range from -22 °F to 257 °F, making it suitable for workshops, garages, or more demanding industrial sites. The diaphragm actuation and 1/4 in NPT ports ensure reliable engagement and straightforward plumbing with a 1/4" compression unloader for streamlined setup.
