Oil Free Air Compressor

The oil free air compressor is the principal part in the air supply device. It converts the mechanical energy of prime motor, usually electric motor, into the pressure energy of air. This product is the device to generate the pressure of the compressed air.

Advantage
1. As the lubricant has high viscosity and can not be removed completely with present equipment, our product is outstanding to get the compressed air without any oil.
2. Nowadays, many dewatering devices are unavailable because of the oil in the compressed air, like cooling dryer, heatless pure dryer, externally heated purge dryer, etc. Yet the clean air compressed by our product protects the dewatering equipment completely so that the cost on maintaining the dewatering device is reduced.
3. Supplying the compressed air, our oil free air compressor will reduce the load of the motor to get the energy saving effect, not influenced by the pressure loss caused by oil remover. At present, good oil remover in third stage engenders the pressure loss from 1 to 1.2kg. As for one 7.5kw product will consume 600W power to increase 1kg pressure. For 10 hours a day, the product will cost 6 degree of electricity. This is a long term invisible cost.
4. Unlike the oil flooded type, this product saves a large quantity of cost on lubricant and filter. Take a 7.5kw oil flooded type for example. Its lubricant consumption is about 5kg every month, about 60 kg for a year. This oil flooded type uses the efficient oil filter to eliminate the oil from the compressed air. The filter element needs to be changed frequently and it costs much.

To sum up, the oil free air compressor is the recommended product to save energy, reduce pollution and production cost at the premise of production demand.
