The air quality of dry oil-free air compressor complies with the requirement of Class 0 in terms of total oil content, as defined in ISO 8573-1.
Silent Stationary Compressor RDO-25OA/W Dry Oil Free Rotary Screw Air Compressors
What is dry oil-free?
Level 0 oil-free, that is, the total oil content (oil brought in during compression + oil vapor in the air) index reaches ≤0.01mg/m³. "Oil-free" means that the gas is not in contact with oil at all during the compression process, that is, there is no oil lubrication between the compression chamber or the rotor of the compressor, but the bearings, gears and other parts in the compressor are still lubricated with ordinary lubricants. Lubricated in the same way, but between these lubricating parts and the compression chamber, an effective isolation shaft seal is adopted.
The air quality of dry oil-free air compressor complies with the requirement of Class 0 in terms of total oil content, as defined in ISO 8573-1.
Dry Oil Free Compressor Product Feature
1.Original German Air-end with World Well-know Screw Technology.
Adopt original German air end with high durability and good quality, which is perfect for compressing pure and clean air.
2. New Noise Reduction Design - Venturi Tube Muffler
The first and second stage of the air-end all adopt the newly developed venturi muffler, and there is also an impedance integrated muffler, which can greatly eliminate the noise emitted by the compressor pipeline.
3. IE4 motor, save your electricity cost, IP54, B-level temperature rise is suitable for harsh environments such as large dust and high temperature.
4. Multiple noise reduction design, calculated according to noise theory, with special flame retardant muffler cotton inside, to reduce the noise of the unit and provide a quieter environment for use.
5. Independent air inlet, reduce intake resistance, multi-function intake valve group, start without load, motor load is small. Use high-efficiency filters to effectively filter particulates in the air.
6. Centrifugal fan with plate-fin cooler has high wind pressure, low noise, external independent suction, exhaust air upward through a specially designed air duct to prevent hot air from returning; cooler modular design, vertical installation, effectively eliminate thermal stress , More stable operation and long service life.
7. Optimized shock absorption pad to reduce vibration and noise.
