High Efficiency PM VSD Oil Free Screw Blower

The High Efficiency PM VSD Oil Free Screw Blower generates a smooth, pulse-free, and continuous airflow through a progressive compression chamber. With a discharge pressure range of 0.4–2 bar, it is particularly suitable for applications requiring low pressure, high flow, and 100% oil-free air.

Key Applications

● Wastewater Treatment Aeration: Provides efficient, low-noise oxygen transfer to enhance the treatment efficiency of biochemical tanks.

● Pneumatic Conveying: Ideal for transporting cement, flour, plastic pellets, etc.; the oil-free characteristic ensures material purity.

● Textile Industry: Supplies constant-pressure, oil-free, and dry compressed air for air-jet looms.

● Food & Pharmaceutical: Features Class 0 oil-free certification, making it safe for direct contact with products.

● Electroplating / Fermentation / Desulfurization: A perfect replacement for Roots blowers, delivering significant energy savings.

Core Advantages & Selling Points

100% Oil-Free & ISO 8573-1 Class 0 Certified

● Guarantees absolutely clean air with zero risk of oil contamination. Ideal for sensitive applications in food, pharmaceutical, and electronics industries.

Ultra-low noise for an improved working environment

● Fully enclosed soundproof enclosure (featuring 50–60mm sound-absorbing cotton) + specialized "anti-silencer" + independent air duct.

● Average noise level as low as 72±2 dB(A), which is 15–20 dB lower than Roots blowers.

Stable operation in high-temperature environments

● The cooler is designed for an ambient temperature of 52℃ and features copper tube heat dissipation (withstanding temperatures above 150℃).

● An independent oil pump provides forced lubrication for gears and bearings, ensuring the unit does not trip during prolonged high-temperature operation.

FAQ

Q1: Is this High Efficiency PM VSD Oil Free Screw Blower truly 100% oil-free?

A: Yes. Our SPVC series adopts a dry-type oil-free twin-screw airend, with no lubricating oil in the compression chamber. It has passed the TUV Class 0 certification, and the test report is available upon request.

Q2: How much electricity can be saved compared to a roots blower?

A: Under actual working conditions, energy savings typically range from 25% to 35%. We provide a free energy efficiency evaluation form. By entering your pressure, flow rate, and electricity cost, you can accurately calculate the annual savings.

Q3: What is the frequency conversion range? Can it run at low frequency for a long time?

A: The frequency conversion range is 60%–100%. The permanent magnet motor has excellent low-frequency characteristics, but we do not recommend long-term operation below 60% to avoid affecting heat dissipation and lubrication. If a wider range is needed, our dual-inverter model is available.

Q4: Is a foundation required for installation?

A: No. The machine comes with built-in vibration dampers. It can be placed directly on a flat, load-bearing ground.

Q5: What is the warranty period? How is after-sales service guaranteed?

A: The complete machine is warranted for 2 years, and the airend for 5 years. We have service networks in major cities across the country, with a 4-hour response and on-site service within 24 hours.

Q6: Is remote monitoring supported? Can it be viewed via mobile phone?

A: Yes. We provide an IoT module. You can monitor real-time operating data, alarms, and energy consumption analysis via WeChat mini-program or a dedicated mobile APP.

Q7: Can the pressure be customized above 2 bar?

A: The standard model has a maximum pressure of 2 bar. If you need 2.5 bar or higher, please contact our sales team for special customization.

Q8: What is the delivery time?

A: For standard power models (22–90kW) in stock, delivery is within 15 days. For high-power or customized models, delivery takes 25–30 days.
