160kW Oil-Free Screw Blower – Energy Saving 32%, ISO Class 0 Certified, Industrial Aeration Blower
Our 160kW oil-free screw blower is designed for medium-to-large scale industrial aeration and pneumatic conveying applications. Featuring third-generation twin-screw rotor profiles and ultra-precision machining, it delivers up to 32% energy savings compared to traditional rotary lobe blowers. It is ISO 8573-1 Class 0 certified, guaranteeing 100% oil-free compressed air – providing the highest level of air purity for your critical processes.
1. High Energy Efficiency – Directly Reduces Operating Costs
Equipped with high-efficiency permanent magnet synchronous motor + VFD for integrated energy savings of 32% (verified against equivalent rotary lobe blowers).
Intelligent matching of pressure and flow prevents energy waste from oversized equipment.
Based on 8,000 operating hours per year at $0.10/kWh, **annual electricity savings can reach approximately $25,000–30,000**.
2. ISO Class 0 Oil-Free Certification
Independently tested and certified by TÜV Rheinland to ISO 8573-1:2010 Class 0.
100% oil-free compression – no risk of oil carry-over, protecting downstream equipment (membrane modules, dryers, valves, etc.).
Ideal for industries with stringent air quality requirements, such as food, pharmaceuticals, electronics, and precision coating.
3. Extended Service Life – High Reliability
Rotors made of high-strength stainless steel with anti-corrosion coating for excellent wear and temperature resistance.
SKF ultra-precision bearings with a design life of ≥ 100,000 hours.
Built-in multiple anti-surge controls ensure stable operation, supporting 24/7 continuous duty.
4. Intelligent Control – Easy to Operate
Standard PLC with 7" touchscreen HMI, displaying real-time pressure, flow, temperature, current, and other parameters.
Supports remote monitoring and fault alarms via Modbus/Profibus for integration into plant DCS systems.
Automatically logs operational data for energy analysis and maintenance planning.
5. Low Maintenance – Reduced Lifecycle Cost
Side-access maintenance design allows filter and lubricant changes (gearbox only) without disconnecting piping.
Oil-free compression chamber eliminates regular oil changes, significantly reducing consumable costs.
Standard warranty: 1 years for the complete unit, optional coverage for the main rotor assembly
Aeration: Provides continuous, stable oxygen supply for activated sludge processes.
MBR (Membrane Bioreactor): Oil-free air prevents membrane fouling and extends cleaning cycles.
Conveying of cement, fly ash, plastic pellets, grains, and other powdered or granular materials in dense or dilute phase.
Oil-free air prevents product contamination – especially critical for food-grade materials.
Supplies sterile, oil-free compressed air for chemical reactors and fermentation tanks.
Meets GMP standards for air quality in cleanroom environments.
Used in flotation, agitation, oxidation, and other process stages.
Dust-resistant design ensures reliable performance in harsh conditions.
Blow molding, packaging, drying, and other applications where air contacts food products – meeting hygiene Class 0 standards.

FAQ
1: How can I verify the 32% energy saving claim?
A: Our data is based on field tests against lobe blowers of the same power. We can provide an on-site energy audit before and after installation, and test reports are available on request.
2: What does ISO Class 0 certification mean, and why is it important?
A: It means 100% oil‑free air (zero contamination). This is essential for food, pharma, electronics, and wastewater applications – it protects downstream equipment and ensures compliance.
3: What is the maintenance schedule and what are the typical costs?
A: Change gearbox oil every 8,000 hours / 1 year, and replace inlet filters every 1,500–2,000 hours. No oil change in the compression chamber – maintenance costs are ~40‑50% lower than oil‑injected models, and all parts are easily accessible.
4: Can this blower directly replace my existing rotary lobe blower?
A:Yes – it's a drop‑in replacement for most standard lobe blowers (same flanges and similar footprint). We supply adaptor kits and on‑site support if needed. The VFD can integrate with your existing PLC/DCS.
5: What is the lead time and how can I get a sample unit?
A: Standard lead time is 25–30 working days after order. Limited stock may be available for urgent needs. Free samples are not offered, but we can arrange a factory acceptance test (FAT) – in person or via video.
