Marvair 40055A Motor 322838-754 Thermal Efficiency: Designed for continuous

Thermal Efficiency: Designed for continuous duty with internal thermal overload protection to prevent winding failure during high-ambient operation

Using it on higher voltage systems will damage the internal contacts and lead to immediate failure

or frequent pressure switch lockout codes (usually Code 31 on Carrier boards) indicating insufficient draft

while decreasing HP will cause the motor to run hot and eventually fail under load

matching all electrical and physical specifications

Marvair 40055A Motor 322838-754 Thermal Efficiency: Designed for continuousThe Marvair 40055A Motor is a high performance 1 3HP blower motor engineered for demanding HVACR applications. Operating on 208 230V single phase power, this unit delivers a consistent 1075 RPM with a versatile two speed configuration to optimize airflow across various cooling cycles. For field technicians and contractors, the 40055A serves as the direct replacement for Marvair 40055 and 40055A SP. While the legacy 40055 model utilized a 1 4HP output,
