primarily to energized blower motors (indoor fans) and heat strip sequencers in electric furnaces or heat pumps

The Fasco A271 features ball bearings for extended mechanical life and improved heat dissipation during continuous operation

resulting in lower mechanical wear and increased longevity in 24/7 cooling environments

when used for PTAC motor replacement

and normally closed terminals as identified on the terminal panel to match your specific burner circuit or pump starter requirements

Marvair 70571 Enthalpy Sensor 322838-752 primarily to energized blower motorsFor industrial HVAC efficiency, the Marvair 70571 Enthalpy Sensor is a critical component for managing economizer functions and indoor air quality. As a solid state C7400A2001 equivalent, this sensor measures the total heat contentboth sensible temperature and latent humidityto determine when outdoor air is suitable for free cooling. Integrating this economizer enthalpy control into your Marvair wall mount air conditioner or heat pump ensures the
