Low lube oil pressure is one of the classic machinery trips. Lose it and bearings fail in seconds, not hours.

Ajax pressure switches give a fast, clear signal when lube oil pressure drops below the set point. They are used on engines, compressors and pumps across oil and gas, power generation and marine sectors. For units in hazardous areas, choose the XP ATEX flameproof model. Built in Stockport, born out of decades of protecting large diesel engines.
