Product feature

1. Industry-leading air end, Adopt original German air end with high durabilityand good quality.

2. IE4 motor, save your electricity cost, IP54, B-level temperature rise is suitable for harsh environments such as large dust and high temperature.

3.New Noise Reduction Design - Venturi Tube Muffler. Multiple noise reduction design, calculated according to noise theory, with special flame retardant muffler cotton inside, to reduce the noise of the unit and provide a quieter environment for use.

4.Independent air inlet, reduce intake resistance, multi-function intake valve group, start without load, motor load is small. Use high-efficiency filters to effectively filter particulates in the air.

5.Centrifugal fan with plate-fin cooler has high wind pressure, low noise, external independent suction, exhaust air upward through a specially designed air duct to prevent hot air from returning; cooler modular design, vertical installation, effectively eliminate thermal stress , More stable operation and long service life.
