OEM replacement condenser fan for a wide range of Coleman Mach rooftop air conditioners. 6-blade, 40° pitch, 11" diameter with 1/2" shaft hole. Includes shaft clamp and screw. Covers 48000, 8000, 7000, and 67XX Series units.
The Coleman Mach 6733-3221 is the OEM replacement condenser fan for a broad range of Coleman Mach rooftop air conditioners spanning the 48000, 8000, 7000, and 67XX Series. The condenser fan sits in the outdoor section of the rooftop unit and is responsible for drawing ambient air over the condenser coil to dissipate heat from the refrigerant. Without adequate condenser airflow, refrigerant cannot release heat effectively — resulting in reduced cooling capacity, higher head pressure, and potential compressor overload.
The 6733-3221 is a 6-blade propeller-style fan with a 40-degree blade pitch and an 11" overall diameter. The 40-degree pitch is engineered to move a high volume of air at condenser fan motor speeds, maximizing heat transfer from the coil surface. The 1/2" shaft hole fits directly onto the Coleman Mach condenser fan motor shaft (Coleman Mach motor 1468-3069) without modification.
Installation includes a shaft clamp and screw for secure mounting. The existing motor wiring and mounting hardware remain in place — only the fan blade is replaced. Always disconnect power to the unit before servicing the condenser fan.

Disconnect power to the rooftop AC unit before beginning fan replacement. Loosen the shaft clamp set screw and slide the old fan blade off the motor shaft. Slide the new fan blade onto the shaft, position it correctly, then tighten the shaft clamp screw securely. Verify the fan spins freely and without contact before restoring power.
