Cleveland Controls AFS-460-137 M/R DPDT Air Flow Proving Switch 0.4/12" WC

The Cleveland Controls AFS-460-137 M/R DPDT Air Flow Proving Switch used in HVAC systems. It is with manual reset that measures air flow by detecting pressure differential across the switch within the range of 0.4 to 12 inches of water column. This switch is commonly utilised in HVAC systems for instance air handlers as well as duct systems. When airflow is outside the range, the switch activates a control system or alarm. This guarantees efficient working of the HVAC system, saves energy, provides for comfortable temperatures and air quality, makes it easier to pin-point problems and remember safety implications of inadequate ventilation.
