Key features

Delivers 0.3 to 0.5 MPa air directly without pressure reducing valve, cutting power waste by 20 to 50 percent versus standard 7 bar screw compressors in textile and cement plants.

PM VSD drive with large low speed rotor matches flow to real demand, saving extra 15 to 25 percent electricity in fluctuating load plants with payback period under 12 months.

Stationary enclosed frame with direct drive oil injected airend runs below 75 dB(A) and supports 24/7 duty for cement conveying and wastewater aeration with minimal maintenance points.

AI-Powered supplier vetting

SummaryThe supplier provides a range of design services with strong R&D capabilities, including ODM and OEM services. They hold multiple certifications such as ISO9001:2015 and CE, indicating compliance with quality and environmental standards. However, their financial data shows zero operating revenue and gross margin over the past three years, raising concerns about financial credibility. The supplier has adequate production capability with a significant annual production capacity for air compressors. They also have structured after-sales services, though limited by the absence of overseas warehouses and agents.

Supplier typeThe supplier offers both ODM and OEM services, indicating they manufacture products based on original designs and for well-known brands.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, and CE certifications, demonstrating compliance with quality, safety, and environmental standards.

Financial creditThe financial data shows zero operating revenue and gross margin over the last three years, indicating a potential issue with financial stability.

R&D capabilityThe supplier demonstrates strong innovation capability with R&D activities and the introduction of new products in the past year.

Production capacityThe supplier has a significant production capability, with an annual capacity of producing 100,000 air compressors.

Customization capabilityThe supplier offers extensive customization options, including full and flexible customization based on samples or designs.

Product Q&A

Q:Q1: What pressure range does this low pressure stationary screw compressor cover?

A: Standard low pressure models output 0.3 MPa, 0.4 MPa, or 0.5 MPa (3 to 5 bar). Custom versions can go down to 0.15 MPa for powder conveying or up to 0.6 MPa for special textile processes.

Q:Q2: How much energy can we save compared to using a 7 bar compressor with reducer?

A: At same air volume, compressing only to 0.5 MPa instead of 7 bar reduces specific power by roughly 25 to 35 percent. Adding PM VSD control brings total saving to 40 to 50 percent in variable demand plants.

Q:Q3: Can it replace a Roots blower in wastewater aeration?

A: Yes. For plants needing 0.3 to 0.5 bar clean oil injected air, this screw unit replaces Roots blowers with lower noise, no pulsation, and 30 percent better efficiency at partial load.

Q:Q4: What flow rate can a 37Kw or 90Kw unit provide at 0.5 MPa?

A: A 37Kw low pressure screw gives about 7.5 to 10 m3/min at 0.5 MPa. A 90Kw unit delivers 20 to 25 m3/min depending on rotor size and cooler design.

Q:Q5: Is the outlet size compatible with existing low pressure piping?

A: Yes. Models use G1.5 to DN150 flanged outlets depending on power. For example 37Kw uses DN65, 90Kw uses DN80 or DN100, matching common cement tanker and textile header pipes.
