Maintaining Car Wash Blow Dryers
Car wash maintenance should include checking your blow dryers and their motors on a regular basis to keep them performing at optimum levels.- Stress Cracks: Visually inspect each motor and fan, and look for visible stress cracks in impellers.
- Intake Screen: The intake screen also needs to be checked and cleaned as needed.
- Impeller Rotation: Verify the correct rotation of the direction of the impeller. The blower will move approximately 50% less air when the impeller is running backward, plus it will draw excessive amp load.
- Greasing: Dryer motors need to be greased annually, so you may want to add this to your annual maintenance checklist.
- Motor Starter: We also recommend checking the motor starter overload relay and fuses, if applicable. Verify that the control voltage is correct for the magnetic starter coil.
- Single Phasing: If the motor makes a buzzing noise and runs slowly, it may be single phasing.
