Description
The Johnson Controls P70GE-4 pressure control switch is an outdoor application pressure control switch for HVAC systems and is built to maintain pressure at a given level. Constructed from thick galvanized steel, and pressure range of 20 to 100 psi makes the product reliable and durable in all weather conditions. Applying the “Open-Low” concept, the switch turns off the circuit when the pressure drops below a specific value which is normally used to on or off appliances such as fans or compressors. One of the primary usages of it is to monitor pressures in HVAC systems that help provide maximum performance and productivity.
