China Wholesaler: 30 Years Factories Water-Injected Oil-Free CHINAMFG Pm VSD Rotary Screw Type Air Compressor for Medical Industry

Product Description

The water-injected oil-free screw air compressor is a high-quality and efficient solution for the medical industry. With its advanced technology and innovative design, this compressor offers numerous benefits:

1. Enhanced Efficiency with Low Temperature

The compressor operates at an exceptionally low temperature of less than 60ºC, allowing for near isothermal compression. This results in increased efficiency, as the superior cooling capability of water removes heat and provides more air per kW of power. Additionally, the elimination of internal coolers and aftercoolers reduces power consumption and minimizes pressure drop.

2. Cost Savings on Maintenance

The water-injected oil-free screw air compressor requires minimal maintenance. The only spare parts needed are air filter elements and water filter elements. Its low operating temperature ensures the long service life of the screw air end, reducing expensive maintenance costs. Furthermore, the reduced stress on other components promotes longevity.

3. Minimized Energy Costs

This compressor saves on energy costs by avoiding the need to combat pressure drop. Often overlooked at the time of purchase, these energy costs can be substantial and significantly contribute to the total cost of ownership.

4. Gearbox-Free Design

With no associated oil lubrication, this compressor eliminates the need for a gearbox, simplifying its structure and reducing maintenance requirements.

5. Reliability and Longevity

The water-injected oil-free screw air compressor has fewer moving parts compared to dry oil-free compressors. This simplifies its design and reduces the likelihood of malfunctions. Additionally, its balance bearing loads extend the service life of the compression element, ensuring low-cost operation.
