High Pressure Compressor DJ-5.5/250 for Valve Factory Leak Testing 250bar

Operation manuals in Chinese and English, test records and the documents required for customs clearance are supplied with the shipment. Any market-specific certification requirements should be stated in your enquiry so we can confirm what can be provided.

Export-grade wooden cases are used as standard. For long-distance sea routes or multiple transshipments, moisture-proof vacuum inner packing and anti-rust treatment are recommended in addition.

Units are supplied in 250 bar, 350 bar and 400 bar classes. The right class depends on the test standard, the rated pressure of the valve, gauge, pipeline or cylinder under test, and the required pressure ramp. Please send your test specification so we can confirm the matching model.

The warranty period is 12-24 months depending on the model. We supply Chinese and English operation manuals and video tutorials, plus remote video guidance for installation and commissioning. Key wear parts such as filters, piston rings and seals are kept in long-term stock for quick dispatch, and urgent enquiries are answered within 24 hours.

The series is designed for continuous duty in testing workshops, using multi-stage piston compression with intercooling and aftercooling. Recommended duty conditions and maintenance intervals are given in the manual supplied with the unit.
