Imperial 1166 Blower Wheel W/2 Set Screws CCW 8-1/16" DIA X 2-1/2" W X 1/2" Hole

An oven fan impeller manages proper internal hot air distribution inside commercial baking equipment by physically accelerating and moving heated air currents through the cooking chamber. Operating with a counter-clockwise (CCW) blade orientation, this squirrel-cage styled impeller pulls stale air from the cavity center and forces it across the heat exchangers or burner tubes to maintain uniform multi-rack cooking. Built with a 1/2-inch center shaft bore hole, a smooth hub profile, and a flat back mounting disc, it fits onto standard high-temperature convection motor spindles where it is locked into place using two integrated set screws. Accumulated grease vapor, carbon buildup, and thermal fatigue can warp the individual blades or cause the blower hub to loosen, leading to vibrating motor sounds, rattling noises, or severe temperature stratification between oven racks. Swapping out a distorted or off-balance wheel effectively resolves these performance failures, eliminating the localized cold pockets that result in unevenly baked goods or prolonged cooking times. This precise 8-1/16 inch diameter by 2-1/2 inch width component is commonly used throughout the foodservice sector inside full-size commercial gas ranges, counter convection systems, and specialized snorkel-style baking lines to protect heating components and secure consistent product turnouts.

Equipment Compatibility:
Air circulation and thermal balancing configurations for Imperial Blower Wheels include commercial gas convection ovens, multi-rack restaurant ranges, heavy-duty production ovens, and specialized snorkel baking lines. This Blower Wheel 1166 is compatible with commercial equipment from leading brands such as American Range, Imperial, Vulcan Hart, Wolf, Royal Range, and Hobart, where high-velocity air movement is required for reliable operation.

Installation Feedback:

"Often mentions that more even heat circulation and improved baking consistency across racks after replacing the blower wheel."

Step1: Turn off the power supply to the appliance completely.

Step2: Access the blower housing inside the unit.

Step3: Remove the old blower wheel from the shaft.

Step4: Install the new wheel onto the motor shaft.

Step5: Tighten set screws securely in place.

Step6: Ensure proper alignment and clearance.

Step7: Restore power and test airflow performance.

• What maintenance is required for the Imperial 1166 Blower Wheel?

  Inspect the blower wheel regularly for dust, debris, and bent or damaged blades. Clean with a soft brush or compressed air, and ensure it spins freely without wobbling. Tighten mounting screws and follow safety precautions by powering off equipment before servicing.

• What are the common issues with the Imperial 1166 Blower Wheel?
