Air filtration system GEA OptiAir
GEA OptiAir is an air filtration system designed to operate together with a preduster. Air containing flour particles enters a cyclone, where centrifugal action separates the particles from the airflow. Separated flour is collected in a bin, while clean air is returned for blowing excess flour off the products. The system helps reduce dust escape from the preduster and maintain controlled airflow during production.

More about the product
GEA OptiAir is designed to filter air in combination with a preduster. Air containing flour and dust is drawn into the cyclone, where the airflow follows a spiral path and centrifugal action moves flour particles towards the cyclone wall. The particles travel down into the collection bin while filtered air leaves the cyclone.
The system returns clean air to the preduster for blowing excess flour from the products. The operator can adjust both the ventilator speed and airflow distribution between the upper and lower blow-off circuits.
A separate filter bag handles excess air, while the integrated bin collects separated material. The machine is equipped with a three-colour signal light indicating running status, a full bin or a machine error.
The OptiAir is designed for hygienic operation in food-processing environments. Product-contact and splash-area components can be accessed for cleaning, and the machine is designed for regular foam cleaning according to the manufacturer’s procedure.
The OptiAir is intended to work as part of a predusting system rather than as a stand-alone production machine.
