XT LASER generally suggest that customers buy screw type oil-free air compressor, power is 7.5KW. The best pressure up to 9 kg (but also to attain at the least 8 kg). The exhaust volume higher than 0.6 per minute. If the customer has bought the very best oil air compressor with two oil filter. So as to reduce some water and dirty.
The fiber laser Screw Air Compressor For Laser Cutting china cutting machine needs to meet up with the cutting requirements of various materials and complex shapes. But it does not operate without a clean, dry, stable compressed air flow. The compressed atmosphere partly made up of high pure oxygen and high purity nitrogen to supply slicing gas to the cutting head. A part provided to the cylinder of the clamping desk 
as a power source. And the last component is used to blow and dirt the optical path program.
From the air discharged from the compressed air through the dryer into the gas tank and gas control cabinet, through a sophisticated processing system, a gas clean and dry, and finally into the three street, were used as cutting gas cylinder, power source and light road dust gas pressure to keep up the normal procedure of laser beam cutting machine.
