3-inch diameter motor with sleeve bearings and thermal protection to handle high-ambient temperatures up to 40°C

the DL1076 is the go-to HVAC blower motor for restoring peak performance in existing air distribution systems

requiring standard brazing techniques and nitrogen purging to prevent internal oxidation

While the 3/8" x 5" copper bulb can be used for air sensing

which prevents premature bearing failure and extends the operational life of the drive motor

Greenheck 460511 Limit Switch 318518-761 3-inch diameter motor with sleeveThe Greenheck 460511 Limit Switch is a critical safety component designed for high performance air handling and ventilation systems. This OEM Greenheck replacement part acts as a thermal safeguard, monitoring air temperature and breaking the electrical circuit if limits are exceeded to prevent equipment failure. Engineered for precision, the 460511 high limit switch features a fixed temperature setpoint calibrated for industrial HVAC applications,
