which directly impacts combustion efficiency and pressure switch stability

High-Temperature Durability: Engineered with materials capable of withstanding the thermal stresses common in furnace and water heater combustion chambers

Operational Reliability: Minimizes mechanical drag on the drive motor

as the 440VAC rating allows it to safely replace 370V units

Inspect the orifice for signs of corrosion

Antunes Controls 8021204014 Pressure Switch Els PW 17895 which directly impacts combustion efficiencyThe Antunes Controls 8021204014 Pressure Switch is a high precision air differential pressure switch engineered for critical HVACR and energy management proving circuits. As a veteran grade SMD Series model, it features a versatile set point range of 0. 17 to 6. 0" W. C., making it an essential component for monitoring fan proving, filter status, and combustion air pressure. This unit utilizes a snap acting SPDT switch (Single Pole Double Throw)
