The MAGNOM in-line Max 20 was installed to prevent the migration of wear metal contaminants between systems on a clients Cat 330D excavator and hammer. The goal was to extend the life of both the excavator hydraulic system and attachments.
The Magnom Max 20 was later replaced by the Max XL (blue unit below) to obtain additional filter holding capacity.
Below are close up photos of the Max 20 core that was removed. Significant accumulation was collected.
