This series of pressure-independent automatic balancing dampers regulate damper positioning and provide precise and automatic airflow in both supply and exhaust applications, which results in energy-saving performance that mitigates stack effect in high-rise buildings and improves comfort for building occupants.
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.
Combining compact size and LED technology, the ProTac 1L and ProTac 2L use one or two 3V CR123A lithium batteries, respectively, which have a shelf life of 10 years. The ProTac 2AA is powered by two AA alkaline batteries.
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.
