The gas booster is a simple device for increasing the gas pressure in the pipeline "after itself". It consists of an electric motor and a centrifugal fan mounted on the same frame. Boosters are equipped with automatic controls that regulate start, stop and operating mode. It allows you to automatically start a second (standby) gas booster in the event of a stoppage of the worker (for example, in case of wear and tear of the belt), while simultaneously transmitting a signal to the operator about the need for service.
