Key features

90Kw low pressure screw airend delivers 21 to 29 m3/min at 0.3 to 0.5 MPa, cutting power waste by 30 percent versus using a standard 7 bar compressor with reducer valve.

Large rotor direct drive design keeps noise below 75 dB(A) and supports repeated start stop cycles for intermittent tank pressure testing duty.

PLC controller with auto stop at set pressure and fault alarm allows unattended test runs, compatible with existing air receiver and safety valve system.

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 is the actual air flow at 0.5 MPa for this 90Kw low pressure compressor?

A: At 0.5 MPa or 5 bar, free air delivery is around 21.5 m3/min. At 0.3 MPa it rises to about 28.8 m3/min. This is measured under ISO 1217 conditions with suction air at 35 degree Celsius.

Q:Q2: Why not just use a normal 7 bar 90Kw screw compressor for tank testing?

A: A 7 bar machine at 0.5 MPa working pressure wastes 30 to 50 percent electricity because it compresses to 7 bar then reduces pressure mechanically. This low pressure model matches the target pressure internally, saving that wasted energy.

Q:Q3: Can it automatically stop when the test tank reaches set pressure?

A: Yes. The PLC touch screen allows setting target pressure such as 5 bar. When the tank and line reach that pressure, the compressor unloads and stops, then restarts if pressure drops during the soak period.

Q:Q4: What inlet voltage options are available for export?

A: Standard is 380V/50Hz/3 phase. We can customize 220V, 415V, 440V, 460V, 60Hz, and even 660V for specific industrial sites. Transformer and starter panel are matched accordingly.

Q:Q5: Is the outlet size compatible with standard air tank testing pipelines?

A: The 90Kw low pressure unit uses DN80 or DN100 flange outlet depending on configuration, which connects directly to standard 3 to 5 bar test manifolds and receiver tanks without reducers.
