Description
VW TYPE LOW PRESSURE NITROGEN COMPRESSOR
This nitrogen compressor is suitable for inlet pressure 5-7barg(70-100psig), exhaust pressure 20-40barg, Low flow laser cutting system.
Characteristics of this compressor
It adopts two-stage compression, air-cooling, which is convenient to use, and ensures good cooling effect of the compressor. The inlet is equipped with an intake pressure controller, the exhaust end is equipped with a pressure controller, and each stage is equipped with a safety valve, If the display is over-temperature and over-pressure. the system will alarm and stop. ensuring safe operation. There is a forklift position at the bottom of the compressor, which can be easily transferred to the construction site.
