Part Number: 81521086031
Description:
Genuine MAN ECAM E-APU2 air dryer and multi-circuit protection valve assembly for Euro 6 heavy-duty trucks. OEM label identifies the part as MAN 81.52108-6031 with WABCO manufacturer number 9325103020, manufactured in 2022 and Made in Poland. This integrated unit prepares compressed air for the braking and auxiliary systems by removing moisture and contaminants and by distributing protected air circuits with pressure management and safety features.
The module is commonly installed on MAN TGX and TGS Euro 6 trucks where it is chassis mounted near the air tanks. It replaces several separate components by combining the air dryer cartridge, regeneration system and multi-circuit protection valve in one compact ECAM/E-APU2 housing. The assembly operates on 24V and is designed specifically for commercial vehicle pneumatic brake systems.
This particular unit was removed from a running donor MAN TGX/TGS Euro 6 vehicle. The air system was checked prior to dismantling and built pressure correctly, with no stored faults relating to the air dryer, so the module is presumed to be in good working order. The used MAN cartridge remains fitted for protection and system testing, but for best reliability the dryer cartridge should be renewed when installing the part on your truck.
Cosmetically the aluminium body shows normal road grime and light oxidation but no visible cracks or broken mounting lugs. All air ports are intact, threads are usable and the electrical connector housing is undamaged. Some hoses attached in the photos were cut during removal and are not guaranteed; we recommend using your existing pipework or new lines. The unit has been visually inspected and lightly cleaned only – it is not overhauled or rebuilt.
This is an ideal cost-effective replacement for a failed ECAM air dryer on a MAN TGX/TGS Euro 6 where a new OE unit is significantly more expensive. Please match the MAN and WABCO part numbers 81.52108-6031 / 81521086031 / 9325103020 with your original unit and confirm compatibility with your chassis number or dealer if unsure.
