Kaishan 3 bar Low Pressure Screw Air Compressors are specially designed for Textile, Cement, Glass, Flue-gas Desulfurization and Pneumatic Conveying application. When a 7-bar standard air compressor is run for a plant air pressure requirement of 2 – 5 bar, it will lead to higher power consumption as compared to Kaishan Low pressure compressors. Kaishan low pressure screw air compressors with their patented low compression ratio can deliver same FAD with 20 to 50% lower power consumption.

RELIABLE AIR END

Kaishan Low Pressure Screw Compressor is incorporated with patented internal compression ratio for Low pressure. This patented design maintains the best specific power at Low pressure of 1.5bar – 5.5 bar pressure range.

KRSA compressors feature Patented “SKY” Screw Element with triplex discharge bearings that have a longer service life as compared to dual bearings. As a result, our products will deliver reliable performance, year after year, with lower maintenance costs.

Larger Rotor Size: To increase the rotor throughput, the Airends of our Compressors are larger than usual. Our Air Compressors are built with 5/6 lobes and larger rotor size which reduces the specific power Consumption and runs in slow speed.

Lower inter-lobe leakage losses: Pressure differences between two neighboring working chambers is small due to a greater number of lobes. This reduces inter-lobe leakage losses. Hence leakage to delivery ratio decreases as the number of rotor lobes increases.

Larger wrap angle & discharge port: A greater number of lobes combined with a larger wrap angle ensures multiple rotor contact. This reduces vibrations and thus minimizes noise. Larger discharge ports decrease the discharge velocity and therefore reduce the discharge pressure losses, thereby increasing the compressor’s overall efficiency.
