Product Description

Automatic Portable Rotary Screw Air Compressor , Small Screw Air Compressor


Portable Rotary Screw Air Compressor Introduction


1 Tooth root shape innovation - tooth root is a key factor impact the efficiency of gas produce, problem-solving method is substantially active and passive parts of the rotor tooth root technological shape revolution, SEC achieve historic leap through select the computer software cutting equation software. This SEC core technology have been far ahead in the business field.

2, length, diameter innovation - optimized twin-screw rotor length: diameter ratio, improve overall work through shortening the distance between both ends of the rotor, make it at higher pressure have a higher volumetric efficiency and significantly reduced by to the oscillation, to reduce mechanical noise and prolong life.

3, Wisdom leading technology, rather than led by technology - the essence of technology is not the crowd seeking imitate, but rather follow itself., with several high-tech fusion of thinking (optimization) improved to achieve energy saving, environmental protection these two new breakthroughs results, and official leading the new generation of full sail air compressor since 5:6 gear asymmetric line rotor launch.
