Oil-free screw blower for chemical plants
1. It adopts multiple patented technologies such as counter-flow devices, and the structural design is advanced and reasonable.
2. The impeller adopts a specially designed three-blade composite profile, which is highly efficient.
3. The processing accuracy of key components is high, ensuring the smooth operation of the blower (vacuum pump).
Oil-free screw blowers are widely used in industries such as food, pharmaceuticals, chemicals, electronics, textiles, and industrial oxygen production. They have been extensively applied in the following areas: 1. Industrial oxygen production: Oil-free screw blowers can be used in oxygen production equipment to provide oxygen for industrial production. 2. Food industry: Oil-free screw blowers can be used in food processing, filling, packaging, and other stages to provide compressed air for food production. 3. Pharmaceutical industry: Oil-free screw blowers can be used in pharmaceutical equipment to provide compressed air for drug production. 4. Chemical industry: Oil-free screw blowers can be used in chemical production to provide compressed air for chemical manufacturing.
Oil-Free Screw Blower Core Features
1. Core Advantages: 100% Oil-Free, Clean Air
No lubricating oil contacts the compression chamber, output air meets Class 0 oil-free standard
No oil mist, no oil gas pollution, does not contaminate pipelines, processes, or products
Suitable for: clean air applications such as wastewater treatment aeration, food, pharmaceuticals, chemicals, pneumatic conveying, fermentation, etc.
2. High Efficiency and Energy Saving, More Power-Efficient than Traditional Blowers
Utilizes internal compression principle, efficiency far higher than Roots blower
High overall efficiency, saving 20%–40% energy compared to Roots blowers
Variable frequency models automatically adjust based on airflow demand, saving even more energy
3. Stable Operation, Low Noise, Low Vibration
Screw rotors mesh precisely, running smoothly
Overall noise usually below 80dB(A), making the workshop quieter
Low vibration, low foundation requirement, easy to install
4. Long Service Life, Simple Maintenance
Frictionless rotors, minimal wear, long main unit life
Oil-free design eliminates maintenance like oil filtration, oil changing, and oil-gas separation
Daily maintenance only requires checking air filter, motor, belts/couplings, keeping costs low
5. Compact Structure, Small Footprint
Integrated design: main unit, motor, cooling, control system
Small size, lightweight, suitable for old factory upgrades or limited space scenarios
6. Intelligent Control, Unattended Operation
Standard PLC control system allows:
Automatic start/stop and airflow adjustment
Protection against overcurrent, overload, over-temperature, and overpressure
Remote monitoring and communication interfaces (485/Modbus, etc.)
7. Wide Application Range
Common pressure: 0.3–1.0 bar(g)
Wide flow coverage, suitable for anything from small to large wastewater plants and industrial production lines
