Johnson Controls Hi-Static Pressure Limit Controller

The P-3610 High Static Pressure Limit Controller is a low volume pneumatic controller designed to return a normally closed fan modulation device to its closed position when the inlet static pressure to the P-3610 rises above its set point. The P-3610 is designed to minimize the possibility of ductwork damage in the event of mechanical or control system failure by limiting the duct high static pressure buildup on the discharge side of the fan or the duct negative static pressure buildup on the suction side of the fan.
