To meet the strict air purity demands of the pharmaceutical, food, and electronics industries, Xiamen Greenair Precision Machinery Co., Ltd., part of Greekn Heavy Industry Group (China) Limited, has established a dedicated clean manufacturing zone for its Oil Free Screw Air Compressor portfolio. This controlled environment is designed to assemble the Fixed Speed Oil Free Screw Compressor and the variable speed oil free models without any risk of contamination, ensuring that the compressors can deliver 100 percent oil-free compressed air in accordance with ISO 8573-0 Class 0 standards from the moment they are commissioned. The precision at the heart of an oil free compressor is the dry screw element, which runs without oil in the compression chamber. In Greenair’s climate-controlled machining cell, the rotors are ground and dynamically balanced to extremely fine tolerances. The coating on the rotors is applied using a proprietary process to reduce friction and improve durability. Following rotor production, assembly of the air end takes place in a cleanroom maintained with positive air pressure and HEPA filtration. Bearings and synchronizing gears are fitted by skilled technicians wearing cleanroom garments, and the fully assembled air end is spin-tested to verify performance before it is cleared for final compressor build. On the final assembly line, the oil free air end is coupled to a high-efficiency IE3 motor. For applications with fluctuating air demand, Greenair assembles the unit as a Variable Speed (VSD) Screw Air Compressor, integrating the PWM inverter and calibrating it to maintain constant discharge pressure while adjusting motor speed. The complete compressor package then enters a test cell where it runs under load while measuring air quality, energy consumption, and temperature stability. The large combined cooler and thermostatic valve design ensure safe operation in ambient temperatures up to 55 degrees centigrade, while the RS485-enabled touch screen controller provides full system visibility. Greenair understands that achieving compressed air purity also depends on the downstream Air Purification Equipment. In an adjacent production area, the company manufactures Adsorption Air Dryer units with twin-tower desiccant beds that can achieve pressure dew points as low as minus 70 degrees Celsius. These dryers, along with high-efficiency coalescing filters, form a complete air treatment package. Additionally, in a separate vacuum pump production cell sharing the same quality philosophy, Greenair assembles its Screw Vacuum Pump series, which provides reliable vacuum for packaging and medical applications. Through rigorous clean manufacturing practices, Greenair guarantees that its entire oil free compressed air and purification portfolio delivers uncompromising air quality for sensitive processes.

To meet the needs of factories with limited floor space and those seeking simplified compressed air system installation, Xiamen Greenair Precision Machinery Co., Ltd., a member of Greekn Heavy Industry Group (China) Limited, has launched its innovative All In One Screw Air Compressor.

This strategic move reinforces Greenair’s ability to supply a complete, factory-engineered Compressed Air System—from the compressor itself to the Compressed Air Dryer, Air Receiver Tank, Oil Separate Tank, and Screw Vacuum Pump. By consolidating the production of these key components in its Xiamen facility, Greenair ensures seamless compatibility and consistent quality across the entire compressed air circuit. The dryer production department is split into two main lines. One line assembles Refrigerant Air Dryer units, featuring brazed plate heat exchangers and energy-saving hot gas bypass valves. Each completed refrigerant dryer is charged with eco-friendly refrigerant and tested to confirm a stable pressure dew point of +3 degrees Celsius. The second line produces Adsorption Air Dryer models, where desiccant-filled aluminum towers are assembled, valving is fitted, and the regeneration logic is programmed and verified. Both dryer types are vital Air Purification Equipment that protect downstream equipment from moisture and corrosion. In the pressure vessel manufacturing section, certified welders fabricate vertical and horizontal Air Receiver Tank units from carbon steel plates using automated welding processes. Every tank receives a hydrostatic pressure test, an internal inspection, and a surface treatment before painting. The same stringent protocols apply to the fabrication of the Oil Separate Tank used in oil injected compressor systems. These tanks incorporate advanced mechanical separation media to reduce oil carryover and are leak-tested under high pressure. The newest addition to the factory floor is the vacuum pump production cell, where Greenair builds its Screw Vacuum Pump series. The dry screw vacuum pump modules are assembled from precisely machined components, synchronized with timing gears, and integrated with a direct-drive IE3 motor and a control panel. Each pump is run on a test bench that measures ultimate vacuum level, pumping speed, and power consumption. The pumps can be used standalone or integrated with Air Receiver Tank buffer vessels and filtration systems for complete vacuum solutions. By bringing the full scope of air treatment, storage, and vacuum production in-house, Greenair can offer matched sets of equipment that are optimized to work together. The company’s manufacturing execution system tracks each item with a unique serial number, and the entire batch can be inspected and shipped as a unified solution. This vertically integrated approach is a direct result of Greenair’s “Customer First” philosophy, ensuring that every component from a single Oil Injected Rotary Screw Air Compressor to a complete Compressed Air System with dryers, tanks, and vacuum pumps meets the highest standards of reliability and efficiency.

In response to the stringent requirements of industries where any trace of oil contamination is unacceptable, Xiamen Greenair Precision Machinery Co., Ltd. offers a complete Oil Free Screw Air Compressor range complemented by high-performance Air Purification Equipment. From Fixed Speed Oil Free Screw Compressor models for steady baseloads to variable speed variants that adjust to demand, the portfolio guarantees ISO 8573-0 Class 0 certified air, protecting sensitive processes in food and beverage, pharmaceutical, electronics, and chemical sectors. The core of the oil-free system is the precision-engineered dry screw air end, which operates with absolutely no oil in the compression chamber. The Fixed Speed Oil Free Screw Compressor delivers a reliable constant flow and is ideal for applications with a stable air demand pattern. For facilities where air consumption varies, the variable speed Oil Free Screw Air Compressor adjusts motor speed continuously, maintaining a consistent pressure while significantly lowering energy consumption. Both versions employ high-efficiency IE3 motors and Greenair’s typical robust design, including a large cooler suitable for ambient temperatures up to 55 degrees centigrade and a thermostatic valve for precise thermal regulation. Achieving truly clean compressed air, however, extends beyond the compressor itself. Greenair integrates the oil-free compressor with comprehensive downstream Air Purification Equipment. To achieve pressure dew points as low as minus 40 or even minus 70 degrees Celsius, an Adsorption Air Dryer with twin-tower desiccant design is employed. This dryer removes moisture vapor that could otherwise promote microbial growth or cause ice formation in critical applications. For general moisture removal, a Refrigerant Air Dryer can be used as a pre-treatment or for less critical uses, bringing the dew point down to around plus 3 degrees Celsius. High-efficiency coalescing and particulate filters complete the Air Purification Equipment setup, ensuring that the delivered air meets the highest purity standards. Greenair’s patented inlet valve design and intelligent touch-screen controller with RS485 interface are standard across the oil-free series, allowing seamless integration into the plant’s overall Compressed Air System.
