▪ Thick steel tank provides high pressure resistance and anti-impact performance against vibration
▪ Double seam welding ensures uniform and dense welds for long-term air tightness
▪ Standard ports for drain valve and safety valve facilitate maintenance and overpressure protection
▪ Internal and external anti-rust treatment slows corrosion and prevents perforation
▪ Optimized tank shape avoids interference with nearby pipelines and valves
▪ Compatible with hand brake valve, booster pump, air pipes and brackets for convenient stock management
▪ Hydraulic and air tightness inspection screens defective tanks for safe and stable air storage

FAQ 

Q：Can reservoir with minor rust spots keep working?
A：Shallow surface rust without wall thinning can be monitored. Replace immediately if pits or weld leakage appear.

Q：What causes continuous air leakage from drain valve?
A：Aging seal of drain valve. Replace drain valve first. Replace whole tank if port thread is damaged.

Q：What faults will air reservoir leakage cause?
A：Slow air accumulation, slow or failed parking brake release and insufficient brake boost.

Q：Is regular draining necessary?
A：Yes, especially in wet and mine sites. Water condensate causes corrosion of tank and valves.

Q：Can I weld leaking reservoir by myself?
A：It is not recommended. Welding on pressure vessel brings explosion hazard due to stress change.

Q：How to store spare air reservoir?
A：Store in dry ventilated area, seal all ports and avoid heavy impact.

Q：What is the function of safety valve?
A：It releases air automatically when pressure exceeds rated value to protect tank and valves from overpressure damage.
