mining industry; mechanical engineering. SUBSTANCE: invention relates to control of compressor plants used in different branches of industry and operated for long periods at below-zero temperatures. Proposed compressor plant has compressor, heat exchanger-recovery unit, end cooler, air collector installed on delivery line and interconnected by main and additional pipelines provided with valves and electrically coupled with control unit, and pneumatic system. Compressor is connected by suction pipeline with air filter being a housing with cover and conical bottom in lower part of which float-condenser in installed. Device in form of convergent nozzle is made in upper part of housing. Gauze is secured at inlet hole of nozzle and deflecting partition is installed after outlet hole. Suction pipeline is connected with cover of filter housing. EFFECT: improved operation reliability at varying weather and climatic conditions, reduced power taken for production of compressed air by reducing amount of moisture getting into compressor with suction air owing to provision of air filter. 2 dwg
