DV-1.2/300 High Pressure Air Compressor, 30MPa for Diving Cylinder Filling

Filling time depends on the receiver or vessel volume, the required final pressure and the DV-1.2/300 m3/min delivery of this model. Send us the volume to be pressurized and the target pressure of 1.2 MPa (30 bar), and we will calculate the filling time for your case.

T/T (commonly 30% advance, balance before shipment or against copy of B/L), L/C at sight, and other methods negotiable for large orders. Payment can also be protected through the Made-in-China platform. Final terms depend on order value and cooperation conditions.

The complete unit carries a 1-year warranty. 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.

Routine maintenance covers inspection and periodic renewal of the intake filter, compressor oil and filter elements. Recommended oil change intervals are 1,000-2,000 hours depending on model and duty cycle. Refer to the manual supplied with your unit for the exact schedule and oil grade.

Low delivery is usually caused by a blocked intake filter, valve leakage or a damaged valve plate, worn piston rings, line or joint leakage, or insufficient speed from low voltage or frequency. High discharge temperature usually points to a dirty cooler, insufficient or over-warm cooling water, high ambient temperature, or valve leakage causing backflow. Abnormal oil consumption is typically worn piston or scraper rings, or an over-high oil level.
