XT LASER generally recommend that customers buy screw type oil-free air compressor, power is 7.5KW. The best pressure up to 9 kg (but also to achieve a minimum of 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 cutting machine needs to meet up with the cutting Screw Air Compressor For Laser Cutting requirements of various components and complex shapes. Nonetheless it does not operate without a clean, dry, stable compressed air flow. 
The compressed air partly made up of high genuine oxygen and high purity nitrogen to provide cutting gas to the reducing head. A part provided to the cylinder of the clamping desk as a power supply. And the last component is utilized to blow and dirt the optical path system.
From the air discharged from the compressed air through the dryer in to the 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 road dust gas pressure to keep the normal procedure of laser beam cutting machine.
