Our advantages :
1. Adopt SKF & NSK bearing.
2. Use ADC12 aluminum alloy material.(same to BMW's wheel hubs)
3. Random installation( vertical or horizontal)
4. Insulation class: F, Protection class: IP54
5. 100% oil free air delivery ( Impeller connected to the motor directly, without any oil lubricating) 
6. No routine maintenance (whithout wheel gear and belt,don't need to do maintenance towards those parts)
7. Quiet operation, low noise(adopt low noise motor, meanwhile inlay muffler is available if lower noise required)
8.Variable output control(pressure or vacuum)
9.Pulsation-free compression(use quakeproof footstand)
10.Long term durability(24H running)
11.Strictly tested before leaving the factory

Applications :
1. Aquaculture (fish and prawn pond aeration)
2. Waste water treatment, sewage treatment system.
3. Pneumatic conveying systems.
4. Lifting and holding of parts by vacuum.
