Prevents Short Cycling: Protects the compressor by ensuring adequate off-time between cooling or heating cycles

Optimized Flow Control: The internally equalized design simplifies installation in systems without significant pressure drops across the evaporator

If you're out in the field and need a direct swap for a failing fan motor in a Bard wall-mount unit

It is standard practice to replace the blind flange gasket every time the valve is dismantled for service

it is designed to work with both standard thermocouples and power-generating thermopiles using the included conversion adapter

York S1-028-15471-000 Isolator 321142-301 Prevents Short Cycling: Protects theThe York S1 028 15471 000 Isolator is a critical mechanical component designed for high performance 1 inch shaft blower assemblies. This rubber shaft mounting acts as a primary vibration dampening isolator, isolating the blower's rotational energy from the air handler cabinet to prevent structural resonance and noise. For contractors servicing York, Luxaire, or Coleman equipment, this HVAC blower bearing isolator ensures that tolerances remain tight,
