Application Ventilation of tanks for hydraulic and lubrication systems, and gearboxes. General The oil levels in the tanks of hydraulic systems are subject to continuous variation due to temperature changes and the operation of cylinders and pressure vessels. In order to prevent over pressure in the tanks, an exchange of air with the external atmosphere is necessary. By the use of a ventilating filter, the outside air that is drawn in is filtered and the ingress of dust is therefore prevented. Special features The ventilation openings are designed that dust on the surface of the tank is not...

Ap-curves for complete filters in Selection Chart, column 2 Dx The abbreviations represent the following p-values resp. finenesses: 2 CL =2 pm Composite 99,5 % efficiency for particles of size 2 pm tested in a single pass test with ISO MTD For special applications, finenesses differing from these curves are also available by using special composed filter media.

Remarks: • The ventilating filters listed in this chart are standard filters. If modifications are required, e.g., with integrated dipstick, we kindly ask for your request. • Ventilating filters in Vandalism Proof design see catalogue sheet 50.20.

Recommended port sizes Measurements Type * The thread dimensions do not exactly conform to the DIN ISO standard thread (functioning with the DIN ISO standard thread is guaranteed)

Layout Sizes The determining factor for selecting the size is the maximum over / under pressure allowed in the container. For versions without double check valves, the initial pressure drop with a clean air filter should not exceed 0,03 bar. For versions with double check valves, the initial pressure drop for air IN with a clean air filter should not exceed 0,1 bar. Filter fineness In the ideal case, the fineness of the ventilating filter matches the fineness of the system filter (see also CETOP RP 98 H). By the use of filter fineness 2 CL the ingress of dust into the tank is effectively reduced....

· With filling filter · 6 hole flange · Nominal flow rate up to 850 l/min

Description Application Filling / ventilation of tanks for hydraulic and lubrication systems as well as gearboxes. Design Filling filter: Ventilating filter: General The oil levels in the tanks of hydraulic systems are subject to continuous variation due to temperature changes and the operation of cylinders and pressure vessels. In order to prevent over pressure in the tanks, an exchange of air with the external atmosphere is necessary. By the use of a ventilating filter, the outside air that is drawn in is filtered and the ingress of dust is therefor prevented. A combined filling filter prevents...
