Including 220V/380V voltage. Highly integrated design, it is an all-in-one machine specially designed for supporting laser cutting machines to provide dry and clean medium-pressure compressed air. It adopts a dedicated high-efficiency host air compressor, a high-efficiency reheating refrigerated dryer, a large-capacity gas storage tank and a four-stage high-efficiency precision filter. The integrated system design has a compact structure and is convenient for customers to install and use directly nearby. The air compressor adopts a permanent magnet synchronous motor drive with inverter adjustment to provide laser cutting machine users with high-quality gas for cutting assistance with stable pressure. The internal standard configuration of the exhaust check valve ensures the reliable sealing of the host bearing when the air compressor is shut down. At the same time, the standard configuration of the high-temperature temperature control valve prevents the exhaust temperature from being too low and causing the lubricating oil to emulsify.
