nitrogen booster compressor for nitrogen filling ,with air-cooling and water-cooling cooling modes, single-acting and double-acting structure, vertical and angle type, medium and high pressure, wind brand series Oil-free lubricating nitrogen compressor with excellent performance, stable operation, high efficiency and energy saving, long service life, widely used in nitrogen laser cutting, nitrogen canning, chemical industry, etc.
The friction pairs of the series of machines involved in gas compression are not lubricated with thin oil. The friction seals such as piston rings and guide rings are made of special materials with self-lubricating properties. The structural advantages are reflected in:
1 There is no thin oil lubrication in the whole compression system, which avoids the possibility of oil contact with high pressure and high purity nitrogen (vertical nitrogen compressor is not completely oil-free type);
2 The whole system has simple machine structure, convenient control and easy operation;
3 For the gas medium of the recycle nitrogen compressor, nitrogen, no pollution, the purity of the nitrogen at the inlet and outlet of the compressor is the same.
This universal nitrogen booster oil free compressor is suitable for inlet pressure 5-7barg (70-100psig), exhaust pressure 150-300barg
10NM3-100NM3/hour nitrogen filling cylinder system
