Oil-free Dry Air Compressor

2.2~30kw Oil-free Scroll Air Compressor

Diesel Portable Screw Air Compressor

Belt & Direct-driven Air Compressor

Oil-free Air Compressor

There is no oil in the water-lubricated screw body, which will not cause oil pollution of the compressed air. It belongs to a completely oil-free screw air compressor. Dry-type oil-free machine bearings, gearboxes, and intercoolers require oil to participate in lubrication and sealing. The high temperature of the unit can easily cause oil leakage to pollute the compressed air. It is a semi-oil-free compressor.

ZIQI Oil Free Water Lubricant Screw Air Compressor Advantages:

1. 100% oil-free , good reliability
There is no oil in the water-lubricated screw body, which will not cause oil pollution of the compressed air. It belongs to a completely oil-free screw air compressor. Dry-type oil-free machine bearings, gearboxes, and intercoolers require oil to participate in lubrication and sealing. The high temperature of the unit can easily cause oil leakage to pollute the compressed air. It is a semi-oil-free compressor.
2. Isothermal compression, high efficiency, no flammable, explosive, etc.
The operating temperature of the oil-free screw machine does not exceed 50℃, and the gas does not expand to save energy by more than 15%. The exhaust temperature of the semi-oil-free screw machine is above 180℃. The high temperature makes the bearing, screw, body, and sealing material have a very short service life and must be expensive. s material. The volatilization of lubricating oil at high temperatures can cause fires and explosions.
3. Power saving: water-lubricated compressor is one of the lower energy consumption of oil-free machines in the world.
ZIQI air dry oil-free air compressor 90KW, nameplate capacity 12.50m?/min (10bar), water-jet all oil-free air compressor 90KW, the actual measured air volume is 14.52m?/min (10bar), the displacement has increased by 16%, This means that users save 16% of electricity. According to the calculation based on running 24 hours a day and the electricity cost of 1.0 yuan/kWh, each unit can save 1.26 million yuan in electricity costs for ten years.
4. The compression temperature is relatively low, the host has a long life, the maintenance cost is relatively low, and the
trouble-free operation cycle is long.The main engine of the water-jet all-oil-free compressor has a general warranty of 5 years and a design life of more than 25 years. Low maintenance costs are a reliable choice for formal enterprises to focus on energy management and reduce product costs.
5. Simple maintenance and no worries
It is as simple as a "water pump" to ensure no worries.
6.Dry
The water content in compressed air is low. All compressors produce 100% saturated water vapor. The pressure dew point of water-injected and oil-free compressed air is less than 40 degrees Celsius. Actually, it contains less water, and a lot of water in the air will be discharged.
