Applicable Scenarios

It serves the pneumatic brake circuit of XCMG ZL50G and ZL50GL wheel loader, widely used in quarry, aggregate yard and construction sites. It stores compressed air and stabilizes air pressure to support repeated braking and air horn function, which is an indispensable safety energy storage part for air-brake loaders.

- OEM size and port layout, bracket holes and fittings match original equipment. No pipe modification required to save installation time and avoid leakage risk
- Thick steel tank with full penetration welding, uniform and strong welds, sufficient pressure margin, resisting cracking under vibration and cyclic pressure fluctuation
- Integrated safety valve and drain valve. Safety valve releases excess pressure automatically. Drain valve removes condensate water to slow internal corrosion
- Anti-corrosion paint coating protects outer surface from mud, dust and rust, suitable for outdoor and humid quarry environments
- Strict air tightness inspection with long holding time. Slow-leak defective products are screened out to keep stable air pressure and reduce compressor overload
- Pre-assembled complete set including valves, fittings and gaskets, ready for installation, convenient for bulk stocking

FAQ 

Q：Can a leaking air tank be welded for reuse?
A：Self-welding is not allowed. The air tank is a pressure vessel. Unauthorized welding weakens steel strength and may cause explosion. Replace the assembly when leakage is serious.

Q：Why does the safety valve keep venting air?
A：Common causes: failed safety valve, faulty compressor pressure regulator or over-set pressure. Check compressor control first, replace damaged valve or whole tank assembly.

Q：How often should we drain water from drain valve?
A：Drain daily in rainy and humid conditions; every 2–3 days in dry quarry. Accumulated water accelerates internal corrosion and causes freeze blockage in cold weather.

Q：What inspection is required after installing new air tank?
A：After installation, fill air to working pressure, apply soapy water on welds, joints and valves to check bubbles. No leakage is allowed before operation.

Q：Can rusty air tank keep working?
A：Light surface rust without pits is acceptable with regular inspection. Replace immediately if there are deep pits, perforation or bulging.
