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.


Brine vapor processing is a component of many manufacturing processes. In this case, it was a chemical plant for plastics manufacturing. In systems like these that process abrasive materials or corrosive gases, it’s important to customize the fan design with high-density, durable materials. For the exhaust fan in this installation, we chose a stainless steel alloy called AL-6XN®, which has specific characteristics that make it resistant to seawater and other highly corrosive environments for higher efficiency, less downtime for repairs and continued productivity.
