Nitrogen penetration can meet the requirements of general compressed air. The pressure of nitrogen turbine compressor is high, and the gear type is more energy-saving. According to the discharge pressure, there are single cylinder (low pressure) and double cylinder (high pressure cylinder and low pressure cylinder) (8-stage compression to 30bar), generally below 30barg, 5barG sealing gas is required (pressure nitrogen can meet the requirements).

The self-cleaning filter generally increases with the increase of gas volume, the number of filter cartridges increases and the number of layers is higher. Generally, it is arranged in two layers above 25000 and three layers above 60000; Generally, a single compressor needs to be arranged with a filter separately and at the upper air outlet at the same time.
