DemirDöküm Compatible AC Indoor Unit Cross-Flow Fan (107x840 mm)

Weakening of the strong airflow you expect from your air conditioner’s indoor unit, annoying clicking during operation or breakage of the fan wheel directly reduce your unit’s cooling and heating efficiency. With a diameter of 107 mm and a length of 840 mm, this spare part is a high-quality cross-flow fan made specifically for the indoor units of DemirDöküm air conditioners. Designed to exact original dimensions, this product restores your air conditioner’s factory quietness and airflow performance.

High-Efficiency Airflow and Vibration-Free Rotation

Thanks to its special aerodynamic blade design, it pushes air out with maximum volume and minimum resistance. The precise balancing carried out during production with the metal balance clips on it ensures the fan rotates without vibration even at high speeds, reducing the load on the indoor unit motor. If your air conditioner makes a mechanical rubbing or knocking noise in addition to the sound of the airflow, you can immediately improve comfort by replacing your unbalanced or cracked fan with this high-standard spare part.

Practical Usage Note for Technicians in the Field

Technician’s Note: When installing your new fan, make sure the flat on the fan motor shaft is exactly aligned with the fan’s set screw. Overtightening the screw can crack the plastic hub, so a "snug but not forced" tightness is ideal. Also check the rubber bushing bearing (mount) that the metal shaft on the left side of the fan sits in; replacing it if worn or lightly greasing it will completely eliminate squeaking and resonance noises that may occur after installation. Before ordering, always measure your old fan to the millimeter with the tape measure held straight.
