Product Description

ULPPRO Low Pressure Screw Air Compressor are designed for industries with low‑pressure air demand (such as textiles, cement, glass, etc.). Their discharge pressure is typically 0.5 MPa (5 bar). Featuring an energy‑efficient compressor unit independently developed for low‑pressure operation, they effectively reduce back pressure, improve operating efficiency, and provide clean air that can meet oil‑free certification standards (e.g., ISO 8573‑1 Class 0), avoiding oil contamination at the source. They are especially suitable for applications requiring high flow rates and low pressure, such as textiles, cement, glass, pneumatic conveying, fermentation, and similar industries.

Product features

1. Employing a large rotor and low rotational speed to ensure high performance of the machine

2. Increasing the oil-gas separation equipment to ensure the oil content at the outlet ≤ 2 ppm

3. The clean air source of the low-pressure screw air compressor reduces the frequency of cleaning the nozzle of the elastic forming machine and improves the quality of the finished products

4. The heat dissipation area of the oil cooler is increased by more than 30%, ensuring normal operation in summer without overheating

5. Independently designing the internal pressure ratio of the main unit, optimizing the input power ratio

6. Intelligent control system, automatically adjusting the exhaust volume according to the customer's usage situation (variable frequency type)

7. Built-in IoT module, enabling real-time monitoring of the air compressor's

operation status through mobile terminals anytime and anywhere
