P10 Series pressure controls open or close electrical circuits as operating air pressure changes. Use with pneumatic systems, pumps, or small air compressors.
P20 Series field replacement low pressure controls, for non-corrosive refrigerants, are used in air conditioning and refrigeration applications.
P67 pressure controls close or open electrical circuits based on a preset air pressure signal. Use with air compressors, fans, pilot lights, resistance heating elements, and other devices.
P70, P72, and P170 controls for low pressure applications control cutout, pump-down, and capacity for commercial refrigeration and air conditioning applications. The P72 models provide direct control of 208 to 240 volt single-phase motors up to 3 horsepower, and 208 to 220 volt three-phase motors up to 5 horsepower.
P77 Series pressure controls are precision-engineered for fan cycling pressure applications. The single-pole, double-throw switch lets you install alarms or other control circuits. Use with common refrigerants as well as air, water, and other non-corrosive fluids. Customize to your application with automatic and manual reset and numerous connection options.
