55kw to 315kw Oil free screw air compressor with dry type fixed speed or VSD PM type
1. 100% oil-free compressed pure air, more energy-saving and more environmentally friendly.
2. High-efficiency oil-free main engine, aviation impeller coating ensures high durability.
3. The unique system design and each high-precision component effectively guarantee the superior performance and service life of the whole machine.
4. Permanent magnet frequency conversion and two-stage compression make the energy efficiency of the whole machine a step further, ensuring energy-saving efficiency under different users and working conditions.
5. The main engine has an independent air intake system, which directly absorbs external cold air, and the large air filter box makes it easy to replace the air filter element.
6. The top door can be turned over to make maintenance and inspection more convenient.
7. The design of the muffler device can effectively reduce the exhaust noise, and the unique structure design of the whole machine has low noise and high efficiency.
