Description
The Johnson Controls P100AP-201 is a direct-mount, encapsulated pressure control designed for reliable system protection in HVAC and refrigeration applications. Featuring an open construction with automatic reset, this SPST control responds to pressure drop conditions — opening the circuit when system pressure falls to 10 PSIG and automatically closing again once pressure recovers to 32 PSIG. Its encapsulated design protects internal components from moisture and contaminants, ensuring long-term durability in demanding field environments.
