Product Description:
UNITED has a series of screw compressors with 5.5~630kW capacity, 0.69~120m3/min FAD and 0.2~1.5MPa pressure range. At UNITED, we also provide services such as design, fabrication, compressor station operator training, energy-saving technology innovation and custom types.

High-Efficiency Energy-Saving Air End
- United Compressor air end highly recognized by the air compression industry with its sophisticated design and precision manufacturing.
- With adopting large diameter and the balanced length-diameter ratio of the screw rotors, the optimized design based on the new 4th generation rotor moulded line subjected to higher-efficiency, so the contact surface, contact line, leak triangle and hydrodynamic characteristics of rotors could reach the optimal performance, further improved the volume efficiency. This screw rotor then has high adiabatic efficiency and low power consumption.
- By using imported large-sized heavy-duty bearing and unique bearing layout, at the same time of ensuring the bearing rigidity, the bearing capacity is much improved.
- The lip type shaft seal of the spiral groove fits with the shaft sleeve made of high-grade bearing steel, ensuring the wear resistance of the shaft seal and shaft sleeve. The shaft seal has a pumping function with high reliability and leakage resistance.

High-Efficiency Particulate Air (HEPA) Filtration:
Heavy-duty air filtration system powered by Donaldson USA, with filtration accuracy up to 99.9% for particles greater than 3μm. Suitable for all kinds of heavy dust environments.
Oil Filter:
Donaldson oil filters, high grade of clean filtration, effectively protect the safe operation of the air end bearing, that can help to extend the service life of the air end.

All valves incorporate new oil filters and temperature controls
This patented design integrates a temperature control valve and an oil filter valve for shorter internal piping connections and fewer leak points reducing failure rates. More importantly, it reduces pressure drop, is more energy efficient and avoids obstacles such as vibrating tube breakage and leaks in the separate installation of the oil filter base and temperature control value.
