The 400LD(N) duplex filters are suitable for direct installation into pressure lines. They are mostly installed upstream open-loop or closed-loop controllers to be protected.
They basically consist of filter head with switch-over fitting (1), a screwable filter bowl (2), a filter element (3) as well as mechanical/visual maintenance indicator (4).
Via the inlet, the hydraulic fluid reaches the filter element (3) where it is cleaned. The dirt particles filtered out settle in the filter bowl (2) and in the filter element (3). Via the outlet, the filtered hydraulic fluid enters the hydraulic circuit.
The filter housing and all connection elements are designed so that pressure peaks – as they may e.g. occur in case of abrupt opening of large control valves due to the accelerated fluid quantity – can be securely absorbed. All filters have one minimess connection (6) each as measuring port at inlet and outlet.
By default, the bleeding is effected via lateral minimess connections (7). As of size 0160, the standard equipment comprises an oil drain plug (5).
Basically, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic maintenance indicator is connected via the electronic switching element with 1 or 2 switching points, which has to be ordered separately. The electronic switching element is attached to the mechanical visual maintenance indicator and held by means of a locking ring.
Notice:
NG1000 is equipped with a divided filter bowl (2), see unit dimensions. This enlarges the servicing height as shown in the dimensional table.
