How it works: Germany-based BW200 high pressure air compressor is W-shaped layout of three compression piston compressor cold wind, it will air a free state, the highest compression to 30MPa, separator and filter unit in the flowing After the device, in addition to removal of water contained in the high-pressure gas, oil and impurities parts, high pressure cleaning and tasteless gas output is trustworthy, secure and reliable breathing air and supporting all types of engineering systems, the unit is equipped with motor overload device make sure you set the pressure range of work to ensure the safety of operating personnel and crew, stepless regulating valve unit finally become a safety barrier. Records crew working hours timer, recording unit running time, in order to provide maintenance basis by the report. End -stage cylinder sleeve using homemade recipes, cast alloy, wear resistance, low coefficient of thermal expansion, easy assembly and disassembly. The unit is simple structure, easy maintenance, low speed low noise, safe and reliable quality. Air quality in line with national GB18435-2001 "diving breathing gas standards, " and in line with European EN12021 "international breathing air standards. "
