BREATHING AIR SYSTEMS BAS 500 Breathing Air Compressor: Common Faults and Maintenance
BREATHING AIR SYSTEMS BAS 500 Breathing Air Compressor: Common Faults and Maintenance
BREATHING AIR SYSTEMS is an American manufacturer of high-pressure breathing air compressors. The BAS 500 is typically used for fire-service SCBA refilling. 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.
Compatible consumables
Our compatible consumables for the BREATHING AIR SYSTEMS BAS 500 cover compressor oil and breathing filter cartridges. They are designed as aftermarket replacements and are not supplied or endorsed by BREATHING AIR SYSTEMS.
