Direct Driven Screw Air compressor
Dehaha DC-30A Rotary Screw Air Compressor is an industrial-grade solution built for continuous, high-efficiency operation. This rotary type compressor features advanced technology, making it suitable for various applications across industries that require reliable, consistent compressed air. Whether you need air or water cooling, this unit offers flexibility.
Key Advantage
- New Generation Molded Line Air End
- 1:1 Direct Drive – Stable & Efficien
- Low Maintenance & Operating Cost
Two Stage Screw Air Compressor
After first-stage compression, air is efficiently cooled to lower second-stage suction temperature. Equal pressure ratios across both stages reduce compression work, minimize internal leakage, and improve volumetric and adiabatic efficiency.
Result
Up to 15% higher air output and 15% energy savings compared to single-stage compressors.
- IE3 PM Motor: Saves 6–7% more energy vs. traditional motors
- Compact Air End: One-shaft design for stability and efficiency
- Level 1 Energy Efficiency: National top-grade performance

DEHAHA dry oil-free screw air compressor primarily utilizes twin-screw compression technology. Its distinguishing feature lies in the fact that only air is drawn into the rotor, while lubrication and sealing are achieved through a specialized coating applied to the rotor tooth surfaces. Since no lubricating oil is required, the compressed air remains free from oil contamination throughout the compression process, ensuring high air purity.
It is widely used in industries such as petrochemicals, pharmaceutical fermentation, food and beverage, electronics and semiconductors, and automotive manufacturing.
