Speedaire 145-175 PSI Pressure Switch

This Speedaire replacement pressure switch is a single-port unit with a 145–175 PSI switching range, designed as a direct replacement part for Speedaire equipment. It provides automatic on/off control of a pneumatic system within that pressure band, enabling the connected compressor or other pressure-sensitive equipment to cycle as pressure rises and falls. The key specification is the 145–175 PSI range, which defines the points at which the circuit energizes or de-energizes, helping maintain consistent operating pressure in compatible Speedaire configurations. This switch is intended for use in systems built around Speedaire components that require a 145–175 PSI control switch, offering a straightforward path to restoring proper pressure regulation when replacement is needed.
