Bosch Rexroth 7 SL Spin-on filter

Bosch Rexroth 7 SL Spin-on filter

The replacement cartridge filter is suitable for direct installation in suction, pressure or return lines. It is installed upstream components to be protected. It basically consists of a filter head (1) and a screwed replacement cartridge (2) with integrated filter element (and/or two replacement cartridges for size 180 and 260).

Optionally, a maintenance indicator (3) and/or a bypass valve (4) are configurable for the filter.
Via the inlet, the fluid reaches the replacement cartridge (2) where it is cleaned. The dirt particles filtered out settle in the filter element. Via the outlet, the filtered fluid enters the hydraulic circuit. With sizes 180 and 260, there is simultaneous flow through both replacement cartridges.
