Full Description

When consulting engineers select and specify fans for HVAC systems, they often specify that the motor for a fan should be a premium efficiency motor. This is critical because most variable frequency drives (VFDs) require a premium efficiency motor. Recent regulations that require engineers to specify premium efficiency motors are discussed.
