Key Product Advantages

100% Oil-Free Air Output for Premium Purity

0ppm residual oil with zero contact between rotor and lubricant. It eliminates contamination risks for food, pharma and electronics production.

PM VFD Direct Drive, 20%-35% Energy Saving

132kW permanent magnet motor with loss-free direct drive. Auto speed adjustment matches actual air demand. Class F insulation & IP55 protection enable stable work in harsh environments.

Low Heat & Less Wear, Ultra-Low Maintenance

Air cooling keeps host temp under 105°C and exhaust only 5~8°C above ambient to avoid overheat stops. Non-contact rotors reduce wear, annual maintenance cost drops below 40% of Roots blowers.

PLC Intelligent Control with IoT Compatibility

Built-in PLC + HMI touchscreen for real-time monitoring and fault alerts. Reserved IoT interface supports remote operation and data tracking.

Compact Low-Noise Structure, Easy Installation

Smooth airflow with weak pressure pulsation for quieter operation. Fits ordinary workshop ground without complex damping base.

Applications & Installation Scopes

1. Wastewater Treatment

Supply stable oil-free aeration air for biochemical tanks to activate microorganisms. It slashes aeration power consumption and avoids sludge pollution. Suggested images: Plant installation shot, aeration tank running scene

2. Pneumatic Conveying

For closed transport of grain, cement, plastic pellets. Zero oil residue prevents raw material contamination and pipe blockages. Suggested images: Workshop conveying pipeline, unit matching layout

3. Chemical & Light Industry

Serves oxidation, textile printing and paper bleaching. Oil-free air protects catalysts and avoids defective finished goods. Suggested images: Chemical factory equipment layout, printing workshop air supply scene

4. Food & Pharmaceutical

Oxygen supply for fermentation, sterile purging for packaging and pharmaceutical production. 0ppm oil fully meets hygiene standards. Suggested images: Fermentation workshop, clean room installation real shot

Frequently Asked Questions

What's the biggest advantage over traditional Roots blowers?

A: It delivers oil-free air, saves 20%-35% electricity and cuts maintenance cost sharply, with lower running noise.

Does this blower produce any oil residue in compressed air?

A: Zero, residual oil content is 0ppm, fully compliant with food and pharmaceutical hygiene standards.

Can it work continuously in high-temperature workshops?

A: Max inlet air temp supports 45°C, air cooling keeps internal temperature below 105°C for non-stop operation.

Is professional shock absorption foundation required for installation?

A: No, its low-vibration design fits ordinary workshop ground without complex damping base.

Can I monitor and control the machine remotely?

A: Yes, the PLC system reserves industrial IoT interfaces for remote monitoring and data recording.

How long is the maintenance cycle?

A: Non-contact rotors greatly extend service intervals, yearly maintenance cost is less than 40% of Roots blowers.
