The blower is designed to suck gas out of coke ovens and supply it through the gas pipeline network to the equipment for trapping chemical products.

The supercharger is designed as a single-cylinder two-stage machine with one-way suction.  The blower casing is made of cast iron, has connectors in the vertical and horizontal planes.  Suction and discharge ports are directed downward.  The flow path of the supercharger consists of two wheels mounted on the shaft, diffusers and guide vanes, which make up the compression stages, which are separated by labyrinth seals.
