Xiamen Greenair Precision Machinery Co., Ltd., now part of Greekn Heavy Industry Group (China) Limited, announces the expansion of its Portable Screw Air Compressor portfolio to support construction, mining, and infrastructure projects. The range includes rugged Diesel Engine Portable Screw Air Compressor models for remote sites without electrical power, and versatile Electric Portable Screw Air Compressor units for locations where electricity is accessible. Both types deliver reliable compressed air in demanding environments, reflecting Greenair’s 20 years of professional manufacturing experience.
Every portable compressor features Greenair’s original twin screw air end with large rotor design and SKF bearings, ensuring high air capacity and long service life even under continuous heavy-duty operation. The power source is matched with a high-efficiency motor in electric versions or a robust diesel engine, driving the air end to produce consistent air flow. Designed for portability, the compressors are mounted on a sturdy chassis with lifting and towing options, enabling easy transport across job sites.
Thermal management is critical for mobile equipment. Greenair equips these portable screw compressors with a large combined cooler that maintains reliable performance in ambient temperatures up to 55 degrees centigrade. A thermostatic valve continuously regulates oil temperature to protect the machine from overheating. The advanced controller provides clear operating data and facilitates troubleshooting on the go. The patented inlet valve with oil stop function prevents oil carryover during start-stop cycles. For electric portable models, the efficient motor and optimized system design reduce fuel or power consumption, while diesel variants offer autonomy and high power density for tools like pneumatic breakers and drills.
Whether you need a Diesel Engine Portable Screw Air Compressor for a remote quarry or an Electric Portable Screw Air Compressor for urban construction, Greenair’s expanded lineup guarantees quality performance. The company remains dedicated to “Customer First” and continuously develops products that empower users with energy-efficient and reliable compressed air wherever it is needed.
