The HF4RTISD493NBC10 accessory is manufactured by Vickers within the Vickers Hydraulic Accessories series and is installed to maintain hydraulic automation systems by filtering return flow to a defined cleanliness level. A Beta ratio of 1000 under ISO 16889 means the element removes 99.9 percent of particles of the test size, supporting a target cleanliness level of 20/18/15. The element follows the standard C construction for conventional media layering, and its collapse rating of 10 bar (150 psi) prevents structural failure during cold starts or blocked-flow events. Normal service is limited to an operating pressure of 7 bar (100 psi), with the same 7 bar listed as fatigue pressure for cyclic loading. A bypass valve opens at 3 bar (43 psi) to keep flow moving when the element is clogged. The allowable temperature range of −30 °C to 121 °C (−22 °F to 250 °F) lets the unit operate with most industrial hydraulic fluids.
The bowl is made of carbon steel to resist external damage, while both the cover and head are aluminum to reduce weight without sacrificing strength. Fluid containment relies on a Buna-N seal that withstands petroleum-based oils across the specified temperature span. System condition can be monitored through a 1/8 NPT indicator port that accepts clogging indicators. The return line connects via a 1.875-12 UN SAE-24 inlet port thread and a 1.5 inch tube size, matching common reservoir hardware. Installation from the tank top is possible because the assembly fits a reservoir opening diameter of 158.75 mm (6.25 in), allowing straightforward removal and replacement during servicing.
