The Fan Affinity Law

The Fan Affinity Law

Typical industrial ventilation systems are designed to operate at full capacity. Extensive observation and case studies have shown that ACTUAL SPINDLE RUN TIME rarely approaches 50% of full capacity during 90% of an average monthly production cycle!

EcoBOSS® Energy Management Systems have been designed to take full advantage of the Fan Affinity Law which clearly illustrates how an EcoBOSS® installation WILL WORK FOR YOU!

When a fan’s CFM volume is reduced by 50% the kWh consumption is reduced to 12.5% of full load.
