The Direct Drive Dynamo centrifugal fans include models up to 24-inch wheel diameter and Gplus (Green Plus) electronically commutated motor (ECM) options up to 2 hp. The fans are SWSI, Class I, Arrangement 4 general purpose air-moving devices designed for supply or exhaust applications in commercial, institutional, and industrial HVAC systems.
Greenheck’s Vektor line of laboratory exhaust systems now offers a direct-drive arrangement with four-options available on Vektor-MH (High Plume), Vektor-MD (High Plume with Dilution), and Vektor-MS (Variable Geometry Nozzle) models.
The Backward Curved Centrifugal Fan, equipped with a plastic impeller, is high-voltage powered by a built-in electronically commutated motor (ECM), which enables the fan to run efficiently with low-energy transmission loss.
AirEffect is a climate control system for large diameter fans. Through automation, AirEffect eliminates the need to constantly monitor and adjust a fan’s speed and direction in response to temperature fluctuations.
Single phasing often occurs in an electric motor when one pair of points on its power contactor fails because of the destructive arcing that takes place each time these points open or close. This arc suppressor is designed for AC power applications that operate between 110-480 V and have a maximum allowable current of 235 A (rms).
These flexible fan packs are engineered to meet stringent low-noise and efficiency requirements in industrial and commercial ventilation, refrigeration, and heat exchange applications.
The OPTIMISER 10 is an easy-to-use resource for original equipment engineers to specify the most efficient, tailor-made Multi-Wing fan for their applications.
This plenum fan features a direct-drive fan with the wheel connected to the motor shaft. With no fan shaft bearings or belts to maintain, it is ideal for array applications in air-handler retrofits or when pressurizing a plenum room.
Equipped with a plastic impeller, this high-voltage fan is powered by a built-in electronically commutated motor (ECM), which enables the fan to run efficiently. Designed for residential uses, the centrifugal fan is widely applied in HVAC, air movements, or home appliances.
Designed with California Title 24 regulatory compliance in mind, these condensers are available with one to 14 fans and single- and double-fan-width models in either vertical or horizontal airflow configurations.
