Maintenance

One aspect of fan maintenance that is often overlooked is fan pulley alignment. In order to maximize belt life and fan performance it is important that the motor and fan hub pulley are in line with one another. If the motor pulley and fan hub pulleys are not in perfect alignment the belt will twist which causes the belt to wear unevenly. The accelerated belt wear not only leads to reduced air moving capacity but also increases maintenance costs due to the fact that a belt that might have lasted well over a year may need replacing in as little as a few months.
