Key features

Oil-Free Air Delivery: Lubrication isolated in bearing/gear chambers ensures clean, oil-free air for sensitive processes.

Low Noise Operation: Three-lobe rotor profile reduces pulsation and noise, achieving less than 85 dBA.

High Efficiency Design: Tight rotor clearances and optimized casing geometry reduce internal leakage for high volumetric efficiency.

Stable Airflow: Positive displacement principle delivers constant volume regardless of downstream pressure variations.

Durable Construction: Rotors never contact each other or casing, minimizing wear and ensuring long service life.

Fast Standard Delivery: Standard models available with a lead time of 5-7 days for quick project deployment.

ISO 9001 Certified: Manufactured under strict quality management with 100% factory testing before shipment.

Customizable Parameters: Power, capacity, RPM, and voltage can be customized to meet specific industrial requirements.

AI-Powered supplier vetting

SummaryThe supplier is a combined company focused on blower, environmental-protection equipment, and gas or liquid separation and purification equipment, with related manufacturing, repair, and parts-processing activities. It demonstrates broad customization, ODM and OEM services, recent product development, documented R&D processes, CAD capability, and 20 R&D patents. Production data shows annual output for four blower product categories, while lead times are stated as within 15 working days in both peak and off-season periods. Overseas services include installation, debugging, repair, maintenance, and training, with Indonesia identified as an overseas service market. The supplier reports some brand OEM experience but no Fortune 500 cooperation. Certification details are insufficient, and its supplier-service assessment process lacks written procedures or followed records. Financial information only identifies years 2021–2023, without sufficient evidence to assess financial credibility.

Supplier typeThe supplier is identified as a combined company rather than an offshore company. Its stated scope covers fan and blower manufacturing and sales, environmental-protection equipment, gas compression machinery, liquid separation and purification equipment, general and special equipment manufacturing and repair, and mechanical parts processing and sales.

After-Sales capabilityThe supplier offers overseas debugging, repair, maintenance, training, and equipment installation, and identifies Indonesia as an overseas service market. However, its service-capability assessment has no written procedures or followed records, and only some approved-supplier names were provided, indicating service offerings are evidenced but service governance is incompletely documented.

R&D capabilityThe supplier reports new products during the past year, ODM services, two R&D engineers, CAD capability, 20 R&D patents, and documented design-input, output, review, verification, and validation records available for audit. It also reports no available SDK, which limits the evidenced software-development capability, but the overall product R&D evidence supports a positive assessment.

Production capacityReported annual output includes 10,000 rotary vane blowers, 2,000 air-bearing turbo blowers, 500 magnetic-bearing turbo blowers, and 10,000 Roots blowers. The supplier also states lead times within 15 working days in both peak and off-season periods and has uniformly followed finished-product inspection instructions, providing explicit evidence of production capacity and operational control.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, flexible customization, and minor customization. It also provides ODM services, indicating broad product-design and adaptation support.

Product Q&A

Q:What is the working principle of this blower?

It operates on the positive displacement principle using two synchronized three-lobe rotors rotating in opposite directions to trap and move air without internal contact.

Q:Is the air output oil-free?

Yes, all lubrication is isolated in the bearing and gear chambers, ensuring clean, oil-free air delivery suitable for biological and sensitive processes.

Q:What are the main applications for this Roots Blower?

It is widely used in wastewater treatment aeration, aquaculture, pneumatic conveying, cement/mining, chemical processing, and food/fermentation industries.

Q:What is the maximum pressure capability?

The blower is ideal for low to medium pressure applications, typically up to 100 kPa, while maintaining high airflow rates.

Q:Can the product be customized?

Yes, OEM and ODM services are available. Customization options include dimensions, power, capacity, RPM, voltage, and other parameters based on samples or designs.
