Compacted Screw Compressor

Screw compressors are an essential component of modern laser cutting operations, providing the compressed air needed to ensure clean, precise cuts, efficient cooling, and optimal performance of the laser cutting machines. With their energy-efficient design, reliable performance, and ability to operate continuously, screw compressors help manufacturers improve productivity, reduce costs, and ensure high-quality results.

Power

7.5-250kW

Working pressure

0.7-1.0MPa

Free air delivery

1.2-43.0m³/min

Advanced High Efficiency Air-End

Adopts industry-leading screw ai endm high efficiency and low rotating speed. with the third generation tooth type of rotor, cutting-edge geometric design-stable, reliablem energy saving and long service life

Flexible Coupling Direct Driven

Adopts direct connection structure without any loss, transmission-efficiency is 100% maintenance cost is low, disassemble is onvinient, greatly save the downtime. Easy Maintenance – Airend maintenance only need to disassemble motor, do not affect each other

Intelligent Control System

Adopts intelligent control system to ensure fully automated intelligent operation, detect exhaust pressure, temperature and other field data, and control the exhaust pressure within the preset pressure range throught the intake valve, so as to output stable pressure.

Safe, Reliable and Efficient Motor

Adpots unique low-speed motor, protection grade IP55 IE3, insulation grade F, suitable for bad working conditions. High balance precision, high speed running smoothly.

Unique Heat Removal & Colling System

Adopts advanced design, harmonica radiator, effectively increase the heat dissipation area, run faster and smoother, and take away the heat of the machine in time. The heat exchange effect of the same area is 30% higher than that of the traditional cooler. Even in region with high temperature and high humidity, the normal operation of unit can be guaranteed
