30MPa Reciprocating Air Compressor for Pressure Testing

Product Overview of the V-3/300 High Pressure Air Compressor

The V-3/300 High Pressure Air Compressor is designed for industrial applications requiring compressed air up to 30MPa(G).

Using atmospheric air as the compression medium, this reciprocating piston compressor delivers a flow rate of 180m³/h (3m³/min) and is driven by a 75kW electric motor.

The V-3/300 is mainly developed for high-pressure applications where stable pressure output and continuous air supply are required, including pipeline pressure testing, pressure vessel testing, and high-pressure air systems.

Compared with conventional industrial air compressors, the V-3/300 focuses on ultra-high-pressure air compression requirements and provides a dedicated solution for applications requiring pressures up to 30MPa.

Applications of the Industrial High Pressure Air Compressor

The V-3/300 serves industrial clients in pressure testing service companies, oil and gas pipeline contractors, and manufacturing plants requiring high-pressure air for leak testing or process charging. Typical uses include pneumatic pressure testing of pipelines and pressure vessels prior to hydrostatic testing, high-pressure air storage for cylinder filling stations, and actuation air for industrial control systems. The skid-mounted format supports both fixed installation and mobile deployment, and the unit can be enclosed in a soundproof cabin or metal cabin for outdoor operation. Customization options cover structural form (D-type, M-type, S-type, W-type, V-type, Z-type), cooling method (water, air, or mixed), installation type (fixed, mobile, skid, cabin), and drive mode (electric motor or diesel engine).
