Description
ER-Series
Air compressors provide clean, good quality oil-free compressors air with injected water into compression process.
High efficiency
The injected water of ER-series is the functions of sealant and coolant.
Sealant: Injected water can reduce leakage between rotors and housing, which improved the compressor efficiency by 15% as compared to dry screw compressor.
Cooling: Injected water is mixed with compressed air and efficiently cool down and dissipate heat generated in compression process. The compression is near to isothermal compression.
High reliability
The start of the art design on airends of ER series provide good air quality perfect performance and high reliability.
Oil free air is the trend of global world compressor market. Environment friendly ,availability are important issues to customers.
Low maintenances intervals
Professional engineering design and precise machining with long bearing life. The maintenance interval is enlarged.
Oil-free Air Compressor application industries:
- Fu Sheng products Quick and good service
- "All-in-one": simple installation. high quality and low service total cost investment.
- Medical Air Supply 100%Oil-free clean air
- Small number of component parts and consumable material Low maintenance cost
- Instrument Air Highly Efficient Air Supply
Advantages of ER Air-End
- Direct coupling driven, low power loss
- 100% oil-free compressed air, ensuring clean air and safety
- Splashing oil lubrication on bearings, which is better than grease lubrication
- Variable speed drive technology ensures stable system pressure and energy saving
Dry Air
Low viscosity injected water is easily separated from compressed air. The separated compressed air is 100% relative humidity (RH) and can be easily dried by a dryer.
Reliable Sealing System
The air-ends of the ER series are supported by precise roller bearings with oil lubrication. The compression chamber and bearing chamber are separated by a buffer chamber with oil seal and water seal. Leakage from the oil side into the compression chamber is avoided.
Low Noise
With injected water, the air-end can run at much lower speeds compared to dry screw compressors, resulting in lower noise. The new design enclosure ensures that the compressor operates in low noise.
Environmental Protection
Alloys and special surface treatments are applied to prevent any corrosion on the air-end and components. Injected water is filtered by a high-quality water filter to ensure clean, good-quality water.
Isothermal Compression
Heat generated in the compression process is managed by injecting water into the compression chamber. Water fills the gaps between the rotors and housing to reduce internal leakage, making the compression nearly isothermal, thus optimizing efficiency. With injected water as a coolant, the temperature of the compression chamber can be cooled down to 40°C in high efficiency and isothermal conditions.
