Reliable High-Volume Ventilation Solutions
Whether your project requires exhaust air removal or fresh air supply, Acme Skymaster fans EC and ECH Series propeller fans offer a practical solution for large-scale ventilation applications. Their high airflow capacity and low-silhouette design make them suitable for a variety of commercial and industrial HVAC systems.
Fan Motor Cooling and Brake Horsepower Performance
The brake horsepower (BHP) capacity of a fan motor depends on the level of cooling provided by the airflow moving across the motor. On Acme-built fans, motor loading above the motor nameplate horsepower rating is designed to operate without causing motor overheating and remains within NEMA-recommended operating limits.
This motor loading capability allows the fan to take advantage of the cooling effect of the moving airstream, providing reliable motor performance while optimizing operating efficiency and overall system cost-effectiveness.
By utilizing this design approach, Acme fans can offer an economical ventilation solution without compromising motor performance when operated within the manufacturer’s specified limits.

Performance shown is for Installation Type A: Free inlet, Free Outlet Power Rating (BHP) does not include drive losses. Performance ratings do not include the effects of appurtenances in the airstream. The sound ratings shown for Model EC is loudness values in fan sones at 5 feet (1.5m) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Inlet fan sone levels.
