product parameters

Product Name: Air Dryer
Part No.: 800902561
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Compressed air drying and purification accessory
System Position: Air circuit system (between air compressor and air-consuming components)
Function: Dehumidification, oil mist removal, impurity filtration
Body Material: Metal housing (subject to actual product)
Surface Treatment: Anti-rust treatment
Installation: OEM interface connection, bracket mounting
Working Condition: Quarry mining, aggregate yard, heavy earthwork and construction projects

Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with heavy loads, dust, and mud splash. It is a key purification accessory for ensuring dry and clean air source in the brake circuit and preventing corrosion and seizure of air circuit components.

▪ OEM interface dimensions and mounting position for direct replacement on ZL50G/ZL50GL
▪ Built-in desiccant effectively absorbs moisture from compressed air to keep the air circuit dry
▪ Oil mist removal and impurity filtration reduce contamination of air circuit valves
▪ Housing structural strength meets air circuit working pressure requirements with reliable sealing
▪ Anti-rust surface treatment adapts to outdoor mud and dust
▪ Can be stocked together with brake valves, hand control brake valves, air reservoirs, and related air circuit accessories

FAQ 

Q：When does the air dryer need replacement?
A: Check whether the dryer has failed when continuous exhaust from the drain port does not stop, obvious water accumulation in pipelines, shell corrosion/leakage, or corrosion and seizure of brake air circuit components occur; replace if necessary.

Q：Is water accumulation in the air circuit always caused by the air dryer?
A: Not necessarily. Check whether the air compressor operates normally, there are air leakage points in the circuit, and the air reservoir drain valve is drained on schedule first. Inspect the dryer’s drying capacity after confirming compressor and drainage are normal.

Q：Can the air dryer be repaired?
A: Some dryers allow replacement of the desiccant cartridge or filter element. If the exhaust valve seizes, the housing corrodes, or internal structure is damaged, replace the assembly directly to ensure drying performance.

Q：What to note during air dryer installation?
A: Confirm interface dimensions and thread specifications match the original, and install according to the OEM orientation (note inlet/outlet direction). After installation, check for no air leakage at interfaces and normal air circuit pressure.

Q：How to maintain the air dryer daily?
A: Regularly check whether the dryer exhaust port operates normally and the housing has corrosion or leakage. Inspect or replace the desiccant cartridge/filter according to maintenance intervals. Keep the air reservoir drain valve draining properly.
