This direct-fired burner fan was designed to move over 150,000 cfm of clean air for a biomass energy application.  Featuring our backward-inclined design, the fan wheel is 89 inches in diameter and operates with nearly 80% static efficiency.

This biomass pyrolysis installation required a fan that can handle abrasive material, gasses, and high-temperatures. We designed a custom radial fan, also known as a paddlewheel fan with an open radial blade design. It featured double-walled housing with thermal insulation and alloy airstream materials to handle high temperatures up to 1500°F. We also built it with a continuously-welded housing interior and a bubble (air-leak) pressure test.

We replaced an industrial exhaust fan originally built by another manufacturer in this brine vapor retrofit installation. The fan is an open radial blade paddlewheel design with a backplate to protect the motor from the material in the air stream. We used AL-6XN® construction material for corrosion resistance and a stuffing box shaft seal to prevent vapor leakage.
