Single screw air compressor
Durable & Stable Airend
Designed with large rotors, oversized bearings and low rotational speed to reduce noise & vibration, extending service life and boosting stability of the airend.
Rotor profiles are precision ground for high rotor accuracy.
Single screw air compressor adopts innovative 5:6 asymmetric rotor profile, fully inspected by high-precision 3-coordinate measuring machines, increasing air delivery by 5%–10%.
Equipped with imported brand bearings.
Special Motor for Air Compressors
High starting torque.
Dedicated air compressor motor fitted with imported brand bearings.
IE3 high-efficiency motor cuts your operating costs.
Designed with a service factor of 1.2.
IP54 protection class, F-class insulation.
Permanent Magnet Synchronous Motor
IP65 protection rating, more stable and reliable than IP23 motors under harsh working conditions.
Oil cooling design stabilizes motor operating temperature for longer service life; no axial cooling fan eliminates fan power loss.
Coaxial layout matched with the airend male rotor removes power loss from couplings and gearboxes.
Built with 38UH magnetic steel, capable of withstanding temperatures up to 180°C.
Custom Vector Inverter
Professionally customized inverter for compressor applications.
Monitors all motor parameters including motor temperature to mitigate risks of motor overheating.
Independent air duct design delivers strong environmental adaptability.
Ultra-fast response with response time below 50ms.
High low-frequency torque, capable of outputting 180% rated torque.
Inner Rotor Cooling Fan
IP44 cooling fan with F-class insulation.
Compared with outer rotor fans, inner rotor fans deliver higher wind pressure and larger air volume for superior cooling performance.
High wind pressure prevents clogging of coolers and filter screens.
Three Core Filter Elements
Air Filter: Filtration area reaches 150% of standard demand, featuring low intake pressure drop and excellent energy efficiency.
Oil Filter: Oversized filter element made of imported glass fiber media; rated handling capacity ≥1.3 times circulating oil volume, with high filtration precision and outstanding durability.
Oil Separator: Imported glass fiber separator core delivers outstanding oil removal performance with low pressure drop.
Special Valves for Air Compressors
Intake Valve: Optimized via low-flow velocity testing with minimal pressure drop to reduce energy consumption.
Minimum Pressure Check Valve: Low pressure drop, fast re-seating performance to prevent air backflow.
Thermostatic Valve (Partial Models): Units fitted with mixed-flow thermostatic valves enable easy startup in low-temperature environments.Single screw air compressor stabilizes unit performance by regulating oil supply temperature of the airend.
High-Temperature Refrigerated Compressed Air Dryer
Counter-flow heat exchange design, more energy-saving and stable than conventional parallel-flow type.
Models rated above 13bar adopt high-efficiency high-pressure resistant stainless steel plate heat exchangers.
Gas-liquid separation efficiency exceeds 99%.
Pressure dew point can reach as low as 3°C.
Allows inlet air temperature up to 80°C.
Precision Filter
Piston-type filter element and housing sealing prevent unfiltered gas bypassing the filter.
New matrix mixed fiber media with large effective filtration area improves removal rate and expands opening area to minimize pressure drop.
Models above 13bar are equipped with differential pressure indicator as standard.
Coated closed foam sleeve resists corrosion from oil and acid to avoid re-mixing condensed liquid into airflow.
Automatic Drain Valve
Electronic automatic drain valve is more stable and less prone to clogging compared with float-type drain valves.
Float-type drain valves are easily blocked due to narrow drain holes.
Optional Zero-Air-Loss Intelligent Drainage Device
Electrical Section
Flame-retardant ABS material
IP65 protection class
Diaphragm
Custom-designed for compressed air drainage characteristics, crack-resistant and highly durable
Solenoid Valve
Stainless steel valve core with piston structure, strong anti-fatigue performance
Liquid Level Sensor
Inductively detects liquid level without direct contact with fluid
Stable, reliable and long service life
Inlet Filtration
Large particulate contaminants trapped in filter cavity to greatly reduce failure rate
Oversized filter cavity with wide-diameter filter plate
Pull-out stainless steel filter plate for easy maintenance
Standard drain ball valve
Simply open & close repeatedly to discharge impurities
