The H4511S4GHB6C05 filter element belongs to the Vickers Hydraulic Accessories series and is manufactured by Vickers for pressure filtration tasks in automated hydraulic circuits. It is intended for installation inside in-line or subplate pressure filters, a configuration identified by its filter type. A beta ratio of 200 at 4.5 µm indicates that it removes 99.5 % of particles of that size to protect precision valves. The element fineness of 5 µm further defines its contamination control capability for servo-controlled actuators. Filtration media is C-Pak, selected to maintain consistent capture efficiency under cyclic flow. Contaminated oil enters on the outside and moves inward because the flow direction is outside-in. Structural stability is provided by a steel center tube and steel end caps that resist collapse during pressure transients. Dimensional data includes an outer diameter of 3.88 in, an inner diameter of 1.61 in, and a length of 18.5 in, allowing it to fit matching Vickers housings.
Pressure loss through the element is limited by an initial differential pressure of 10 psid, so pump horsepower is not wasted at start-up. The media can tolerate a differential pressure of 150 psid before bypass is required, giving margin for dirt loading. Maximum flow rate is 568 L/min (150 gpm), supporting large power units without parallel filtration. The assembly withstands a working pressure of 310 bar (4500 psi) for compatibility with high-pressure servo loops, and Buna-N seals maintain oil containment across this range. Operation is permitted up to 225 °F, covering common reservoir temperatures in mobile and industrial equipment. These limits qualify the H4511S4GHB6C05 element for continuous duty in hydraulic automation where fluid cleanliness, pressure integrity, and thermal stability are mandatory.
