DIVEX (SUBSEA) DIVEX SEAL Breathing Air Compressor: Common Faults and Maintenance
DIVEX (SUBSEA) DIVEX SEAL Breathing Air Compressor: Common Faults and Maintenance
DIVEX (SUBSEA) is a British manufacturer of diving and breathing air compressors. The DIVEX SEAL is typically used for commercial diving cylinder filling. The notes below cover practical operation, maintenance points and compatible consumables.
Common faults and diagnosis
Oil carry-over
If the delivered air smells of oil, inspect the separator and confirm the oil specification. A non-breathing-grade oil will fail EN 12021 purity limits.
Filter saturation
A slow pressure build-up may point to a saturated final filter rather than a pump fault; check the filter differential before overhauling.
Low or unstable pressure
Low final pressure usually points to leaking valves, worn seals or an undersized drive. Verify stage pressures and valve condition before assuming a major overhaul is needed.
