Scope

This document establishes the efficiency grades of ventilators. It applies to all motor-driven ventilator systems that utilize a specific combination of components defined as follows:
a) Ventilator aerodynamic performance determined according to recognized performance standards;
b) Multi-phase induction motors with a nominal motor efficiency specified in this document;
Note 1: Other types of motors are explicitly excluded.
c) Pulse-width modulation variable-frequency drives (VFDs) used with a single motor;
Note 2: This does not include single VFDs serving multiple parallel ventilator motors.
d) Mechanical power transmission devices using V-belts, flat belts, toothed belts, or couplings.
