Plasticair builds a complete line of high velocity, high dilution plume exhaust fans for labs to prevent the reintroduction of contaminated exhaust air into outside air intakes. The fans are made from corrosion resistant FRP, glass fiber reinforced plastics. All fans meet a 125 MPH wind load. 150 MPH wind load is available. Motors and drives are located out of the air stream. Hardware is stainless steel. All FRP meets the 0-25 flame spread per SDTM-E84 and is UV protected.
