Description
The Cleveland Controls RFS-4001-038 SPDT Pressure Switch which is used for measuring the air pressure in HVAC systems. Installed within a range of 0.15-5.0”WC it measures the pressure differential and actuates an electrical switch to turn on or off connected equipment. This switch is normally fitted in air handlers, fan coil units and rooftop units to facilitate the right airflow and system performance. Advantages are that the sensors operate without failure, detect pressures with precision and are simplicity to install ensuring the HVAC system is safe and effective. It ensures efficiency and eliminates possible problems associated with improper air flow in the HVAC system.
