Mahle Hydraulic Filter (HC9) Fits Mercedes Unimog

This Mahle hydraulic filter (HC9), is designed for vehicles with automatic transmission and is suitable for selected Mercedes Unimog U trucks available from 2013 onwards.

Increased service life makes also higher demands on the filter media in oil filters, particularly as the new engine generations with direct injection increase the problem of oil aging.

With the use of new fully synthetic high performance oils, replacement intervals of up to 30,000 miles are reached – with a trend to even longer intervals. However, due to the new general conditions, conventional filter raw materials are becoming less suitable, especially as the excessive nitration of the oils leads to embrittlement of the filter medial. The response from Mahle: a fully synthetic two-layer fleece made of polyester, consisting of a support and a filtration layer. This makes it possible to achieve highest filtration performance with best stability – and at the same time block forming in the pleats can be avoided. Compared with cellulose fibres, the aging stability of the new oil filter medium is 7 times higher – and it offers the same or even lower pressure drop at significantly increased dirt pick-up capacity.
