Economizer: Hooded Propeller Fans with Mix, Recirculate, Supply and Exhaust Modes

Building ventilation requirements are often dictated by changes in the outside air temperature, production processes within a facility and / or occupancy within a facility. LOREN COOK COMPANY's Economizer Fan offers the flexibility to maintain comfortable temperatures in factories, gymnasiums, equipment rooms, warehouses, manufacturing plants or other facilities with a high internal heat load. The mixing of cool outside air with warm inside air, "free cooling," provides a more comfortable air temperature to any facility. It is the fan's most economical function. The Economizer Fan can also recirculate inside air, supply cool outside air to a facility, or exhaust warm or contaminated air.
