The Lennox 80W57 SPST Pressure Switch 0.65" WC is a safety control component designed for gas-fired HVAC heating systems. It monitors air pressure within the furnace venting system and activates when the pressure reaches 0.65 inches of water column, allowing the system to operate safely. The SPST design opens or closes the electrical circuit based on pressure changes. Commonly used in residential furnaces and heating equipment, this switch helps verify proper draft and airflow, improving system safety, ensuring reliable operation, and protecting the furnace from unsafe operating conditions.
For an efficient and reliable HVAC system, the Lennox SPST Pressure Switch is a great choice for optimal system performance.
