Belt Drive Propeller Roof Ventilators
Models EC and ECH
Models EC and ECH are low silhouette belt drive propeller fans for exhaust or supply ventilation. Capacities up to 74,200 CFM and up to 7/8 inch static pressure. EC and ECH fans are designed for high capacity general ventilation. Typical applications include a wide range of commercial, industrial, and institutional facilities such as schools, hospitals, prisons, and assembly areas.

The brake horsepower capability of a fan motor is dependent on the degree of cooling the motor receives from the moving air stream over the motor. The motor loading beyond the motor name plate rating on Acme built fans does not overheat the motor and is within NEMA recommended limits. It is therefore not detrimental to the motor and is economically desirable.
Performance certified is for Installation Type A: Free inlet, Free Outlet Power Rating (BHP) does not include transmission losses. Performance ratings do not include the effects of appurtenances (accessories).
The sound ratings shown for Models EC and ECH are loudness values in hemispherical sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Inlet hemispherical sone levels.
The sound ratings shown for Models EC-S and ECH-S are loudness values in fan sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Outlet hemispherical sone levels.

Propeller Roof Fans
Performance certified is for Installation Type A: Free inlet, Free Outlet Power Rating (BHP) does not include transmission losses.
Performance ratings do not include the effects of appurtenances (accessories). The brake horsepower capability of a fan motor is dependent on the degree of cooling the motor receives from the moving air stream over the motor. The motor loading beyond the motor name plate rating on Acme built fans does not overheat the motor and is within NEMA recommended limits. It is therefore not detrimental to the motor and is economically desirable.
For more information on this product contact your sales support.
