Cleveland Controls AFS-298-391 Sensing Switch 321702-401 this SPST (Single Pole Single

this SPST (Single Pole Single Throw) switch ensures the combustion blower is moving sufficient air to safely vent flue gases before the ignition sequence initiates

Enhanced Safety: Maintains the specific airflow requirements necessary for proper pressure switch operation

The Watts LFBP30 is a control valve that actively regulates pressure by bypassing fluid back to a tank or the pump suction side during normal operation

This component is designed for specific Carrier

Rugged Construction: Utilizing stainless steel bellows ensures resistance to vibration and long-term fatigue in high-pressure environments up to 245 psig MWP

Cleveland Controls AFS-298-391 Sensing Switch 321702-401 this SPST (Single Pole SingleThe Cleveland Controls AFS 298 391 is a high performance air pressure sensing switch designed for precision in commercial HVAC and energy management systems. Engineered as a general purpose differential pressure switch, it monitors positive, negative, or vacuum air pressure with a field adjustable set point range from 0. 05" w. c. to 12. 0" w. c. This unit is factory calibrated to change contacts on increasing pressure at 0. 30" w. c. ( 0. 02" w. c.),
