Reliable exhaust airflow is essential for commercial kitchens, restrooms, production areas, and other occupied spaces. Small problems often give warning before the fan stops completely.
Pay attention to airflow and sound
- Weak exhaust at the hood or grille
- Squealing, scraping, rattling, or heavy vibration
- A fan that starts slowly, cycles unexpectedly, or will not start
- Grease, dust, or debris collecting around the fan
- Excessive motor heat or a burning odor
Keep grease and debris controlled
Grease buildup can restrict airflow, unbalance the fan wheel, strain the motor, and create a safety concern. Follow the cleaning schedule required for your kitchen and operating conditions.
Do not ignore belt or bearing noise
A loose or worn belt can reduce airflow and damage pulleys. Bearing noise and vibration should be addressed before they lead to motor or fan-wheel failure.
Call before the fan stops
If airflow drops or the fan becomes noisy, shut it down when safe and arrange service. Avoid operating equipment that is overheating, severely vibrating, or tripping electrical protection.
