Abstract
A method and apparatus to monitor air filter life and motor usage in a forced air filtration system is disclosed. The forced air filtration system uses a constant volume (CV) motor to drive a fan or blower to force the air through the filter. The generated data allows the users to schedule air filter replacement and motor maintenance to maintain system performance and avoid interruption of normal operation due to equipment failure. The motor life monitoring may also be used by equipment manufacturers and users to track equipment life expectancy.
