General Maintenance Suggestions

The Concrete Block Exhaust Fan requires very little 
maintenance. However, since small problems left 
unchecked over time could lead to loss of performance 
or early motor failure, we do recommend that the unit be 
inspected periodically (once or twice a year).
The fan motor and wheel(s) should be checked for dust 
and dirt accumulations. Dirt buildup can lead to loss of 
performance and motor overheating. Cleaning can be 
accomplished by brushing off any dust or dirt that may 
have accumulated.
