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 demonstrates broad customization, ODM and OEM capabilities, reports new product development within the past year, and operates CNC, five-axis and three-coordinate machining facilities. Production information states annual output of 100,000 air-compressor pieces and 10 quality inspectors, although finished-product inspection instructions are not supported by written records. Service procedures, corrective actions and complaint handling have documented procedures and records. The supplier offers in-stock capacity and service offerings in Russia, but has no overseas warehouse, showroom, agents or branches. Certifications include ISO9001:2015, ISO45001:2018, ISO14001 and CE. ERP, OA, CRM and SAP systems are reported. Financial credibility cannot be assessed because the supplied financial slices contain inconsistent and incomplete figures, which are not reproduced here. A known-brand OEM claim is provided, but no specific customer names or case details are available.

Supplier typeThe supplier provides ODM services, OEM services for known brands, and operates CNC machining, five-axis machining and three-coordinate machining facilities. This supports classification as a manufacturer with design, machining and OEM/ODM capabilities.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018 and ISO14001 certifications, as well as CE product certification capability. These are explicit certification holdings or capabilities in the provided data.

After-Sales capabilityThe supplier has documented procedures and records for service assessment, corrective and preventive actions, and customer complaints. It offers debugging, maintenance and repair services in Russia, but has no overseas agents or branches; therefore, the documented service process and stated offerings support a positive assessment, while geographic coverage is limited.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and supports customization from samples, designs and full specifications. It does not have an available SDK, but the stated product-development and ODM evidence supports innovation capability.

Production capacityThe supplier reports annual productivity of 100,000 air-compressor pieces, 10 quality inspectors, CNC-based machining facilities, valid contracts with associated subcontractors, in-stock capacity and a one-month average lead time in both peak and off-season. Finished-product inspection has instructions but no written records, indicating a documented-control limitation but not an explicit failure of production capability.

Customization capabilityBoth R&D and design-service records list customization from samples, customization from designs, full customization, minor customization and flexible customization. The repeated and comprehensive customization scope is explicit evidence of strong customization capability.

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.
