Function, cross-section

The 350LE(N) inline filter is designed for direct installation into pressure lines.

It consists primarily of a filter head (1), a threaded filter bowl (2), a filter element (3) and a mechanical optical maintenance indicator (4). For filters with low collapse filter elements (= pressure differential code letter A), a bypass valve (5) comes standard.

The fluid passes through the inlet to the filter element, where it is cleaned. Any dirt particles filtered out collect in the filter element. The filtered fluid then enters the hydraulic circuit through the outlet.

The filter housing and all connection elements are designed so that pressure spikes — as they may occur, e.g.,

due to an accelerated fluid quantity from large control valves opening abruptly — can be safely absorbed.

Sizes 0160 and larger come with a drain screw (6) standard.

Size 1000 comes with a two-part filter bowl, with the filter bowl fixed to prevent the bowl from spinning in the filter head.

An electronic switching element (7) can be added to the mechanical optical maintenance indicator in order to integrate it into an electric circuit. The electronic switching element must be attached to the mechanical

visual maintenance indicator and held with the locking ring supplied. The electronic switching elements are connected with a mating connector or cable connection.

The electronic switching element must be ordered separately.
