Stork Air malfunction
Stork Air bearings worn
Worn bearings are among the most common causes of noise, vibrations, and a heavy-running motor in Stork Air ventilation units, HRVU units, and roof fans. Timely intervention can often prevent further damage.
- Grinding or squealing noise
- Motor runs heavily
- Overhaul often possible
Symptoms of worn bearings
- Grinding or squealing noise.
- Increasingly loud humming.
- Motor runs heavily or irregularly.
- Vibrations in the ventilation unit or ducts.
- Reduced ventilation performance.
How do bearing problems arise?
- Normal wear and tear from years of use.
- Dirt or dust in rotating parts.
- Moisture or contamination.
- Imbalance of fan or motor.
- High load for a long time.
When do bearings need replacement?
A bearing that starts to wear often first makes a slight grinding or humming sound. As wear increases, humming, vibrations, and reduced performance become more noticeable. Therefore, do not wait too long to prevent further damage to the motor.

Start the troubleshooterOverhaul or complete replacement?
In many Stork Air motors, worn bearings can be replaced during an overhaul. This means that the complete ventilation unit or HRVU unit does not have to be replaced immediately. This is often a more sustainable and cost-effective solution.
