Optimized Airflow Dynamics: Maintains the critical seal required for proper static pressure and safe exhaust of combustion gases

since this is a 2PDT relay

Dual-Function Reliability: Simultaneously manages the 35 MFD compressor load and 3 MFD fan motor load from a single housing

Scaling it to 120V or 240V circuits will cause immediate component failure and poses a safety risk

We recommend this genuine OEM part to ensure the exact wall thickness and diameter required to maintain the laboratory-certified seal of your furnace cabinet
