Bosch Compatible Cross-Flow Fan (780x107 mm)

Distributing air into the room quietly, evenly and efficiently in AC indoor units, the 780x107 mm Cross-Flow Fan brings your air conditioner’s performance back to its original level. It is a high-quality spare part designed to replace fans that have lost their function over time due to dust build-up, imbalance, bearing wear or breakage. It is compatible with units supporting these dimensions, notably Bosch.

Quiet Operation and Vibration-Free Airflow

Directly affecting your indoor unit’s airflow performance and your comfort, this cylindrical fan directs air with maximum efficiency thanks to its aerodynamic design. Thanks to its flawless blade arrangement and correct shaft bearing fit, it does not cause balance (runout) problems; this allows your air conditioner to run extremely quietly without annoying vibrations and noises.

Practical Usage Note for Technicians in the Field

Technician’s Note: Before installing the new fan, always check the fan motor shaft and the rubber bushing bearing on the left side for rust or deposits. If necessary, sand lightly and clean with a rust remover/lubricant spray. When fitting the fan onto the shaft, make sure the set screw lines up exactly with the "flat-cut" surface on the motor shaft. Tightening the screw with excessive force can crack the plastic hub; a snug tightness is ideal to prevent imbalance.
