Diluting primary airstreams before toxic air is emitted through exhaust stacks can help designs lower toxic concentrations and therefore with corrosion, odour and general safety. Our FRP Induction stacks are constructed to withstand 125 MPH as a standard and can be designed to endure up to 200 MPH on special request. Our SKYPLUME G1 stacks are tested to AMCA 260, and our SKYPLUME G2 stacks have been tested in wind tunnel conditions and have shown no downwash phenomenon up to 30 MPH crosswind while achieving 205% induction rates in high winds.
