XT LASER generally suggest that customers purchase screw type oil-free air compressor, power is 7.5KW. The very best pressure up to 9 kg (but also to accomplish a minimum of 8 kg). The exhaust volume greater than 0.6 each and every Screw Air Compressor For Laser Cutting minute. If the customer has bought the best oil air compressor with two essential oil filter. In order to reduce some water and dirty.
The fiber laser beam cutting machine needs to meet up with the cutting requirements of various components and complex shapes. But it does not operate without a clean, dry, stable compressed air flow. The compressed atmosphere partly produced up of high pure oxygen and high purity nitrogen to provide trimming gas to the slicing head. A part supplied to the cylinder of the clamping desk as a power resource. 
And the last component is used to blow and dust the optical path program.
From the air discharged from the compressed air through the dryer in to the vehicle’s gas tank and gas control cabinet, through a sophisticated processing system, a gas clean and dry, and finally into the three road, were used as cutting gas cylinder, power source and light street dust gas pressure to maintain the normal operation of laser cutting machine.
