Home > Products > F62



The F62 airflow switch detects air flow or the absence of air flow by responding only to the velocity of air movement within a duct.

The control can be wired to open one circuit and close a second circuit (SPDT) for either signaling or interlock purposes.

Failure of air flow during normal operation of air handling systems may cause over-heating, coil icing and other conditions that may be detrimental to the equipment.

Typical applications include make-up air systems, air cooling or heating processes and exhaust systems.
