Electric drive low-pressure screw air compressor is a set of intelligent conveying system for bulk materials, which is used for pneumatic conveying of bulk materials. Our design is aimed at market demand, providing safe, efficient, and high-quality energy-saving products for the tank truck or tank ship’s powder conveying market.

Features:

1. Industry-specific design: It is low-pressure and no-water design for building materials, specially designed for concrete batching plant. with super oil-water system, unique water removal process design. It also eliminates unsuitable processes for industrial screw machines.

2. Power saving: pneumatic pressure of bulk materials is 0.2~0.5MPa. If a conventional 0.7MPa air compressor is adopted, it will cause a huge power waste. Our low-pressure screw air compressor can save 20~50%.

3. Low noise: It greatly elinate the largest noise sources in the production site of concrete batching plant - diesel engine and pendulum air compressor.

4. Unique water removal design: It discharges air completely and removes water: The entire system does not require additional air storage tanks, freezing dryers and oil-water separation equipment.

5. Stable and reliable quality: It adopts special high efficiency energy-saving low pressure screw compressor, it can run 24 hours continuously, design 25 years life.

6. High-efficiency, environment-friendly and energy-saving: It adopts electric energy to replace the fuel consumption of traditional models, and it improves transmission efficiency by more than 30%.
