The F262 Airflow Switch detects airflow or the absence of airflow by responding only to the velocity of air movement within a duct. The single-pole, double-throw (SPDT) control can be wired to open one circuit and close a second circuit for either signaling or interlock purposes. Airflow failure during the normal operation of air handling systems may cause overheating, coil icing, or other conditions that may be detrimental to the equipment.
Application
The F262 switch detects airflow or the absence of airflow by responding only to the velocity of air movement within a duct. The SPDT control can be wired to open one circuit and close a second circuit for either signaling or interlock purposes Failure of airflow during the normal operation of air handling systems may cause overheating, coil icing, and other conditions that may be detrimental to the equipment.
Typical applications include:
• Make-up air systems
• Air cooling or heating processes
• Exhaust systems
The control has a Type 3R (NEMA) enclosure with an integral mounting plate. A mounting plate gasket is supplied with each switch.
Features
• Type 3R (NEMA) Polycarbonate enclosure allows use in indoor applications and provides dust protection and is approved for use in a plenum according to NEC
• Dependable dust-protected SPDT snap-acting PENNswitch detects the presence or absence of airflow
• Large wiring space makes wiring convenient and easily accessible
• Easily accessible range adjustment screw allows easy field adjustment
