5-inch diameter fan assemblies

LP applications require a smaller orifice diameter due to the higher energy density and pressure of liquid propane

maintaining the precise air-to-fuel ratio necessary for optimal thermal efficiency

For contractors performing maintenance on Carrier commercial HVAC systems

High-Temperature Durability: Engineered with composite materials designed to withstand cyclical thermal stress and acidic condensate exposure

Heat Controller R68DD0014 Pressure Switch Els PW 29614 5-inch diameter fan assembliesThe Heat Controller R68DD0014 Pressure Switch is a critical safety and operational component designed for negative pressure monitoring in residential and light commercial HVAC systems. Calibrated to a precise . 2" WC (Water Column) set point, this diaphragm actuated switch ensures the draft inducer is venting combustion gases effectively before allowing the ignition sequence to proceed. Engineered for compatibility with Comfort Aire, Century, and
