Supco SFC300400 Fan Cycle Switch 300 PSI Open/400 PSI Close

The Supco SFC300400 Fan Cycle Pressure Switch is a pressure-operated control that assists in controlling the use of fans in refrigeration and cooling systems. It slightly opens at around 300 PSI and closes at around 400 PSI with the system pressure variation during use in air conditioners, heat pumps and other packaged HVAC systems. The switch is installed in the right pressure line and connected to the control circuit as required. This part enables efficient heat rejection, assists in maintaining the operating conditions and leads to the stable and reliable performance of the system after cycling the fan depending on the pressure levels.
