China Custom Ultra Quiet Water Injected Oil-Free CHINAMFG Pm VSD Rotary Screw Type Air Compressor for Auto Shop Painting arb air compressor

Product Description


1. Enhanced Efficiency with Low Temperature

Experience near isothermal compression with an incredibly low running temperature below 60ºC. The advanced cooling capability of water ensures maximum air output per kW of power, eliminating the need for internal coolers and aftercoolers. This significantly reduces power consumption and minimizes pressure drop.

2. Cost-Effective Maintenance

With only air filter elements and water filter elements required for spare parts, our compressor minimizes maintenance costs. The low operating temperature ensures the longevity of the screw air end, saving you from expensive maintenance expenses. Additionally, low temperature reduces stress on other components, increasing their lifespan.

3. Combatting Pressure Drop without Extra Energy Costs

Many compressors require additional energy to combat pressure drop, resulting in high costs that contribute significantly to the total cost of ownership. Our compressor eliminates this need, saving you money in the long run.

4. Gearbox-Free Design

Our compressor operates without a gearbox, eliminating the need for associated oil lubrication.

5. Simple Yet Durable

With fewer moving parts than dry oil-free screw air compressors, our design reduces the likelihood of failures. Balanced bearing loads also extend the service life of the compression element, providing you with a cost-effective operation.
