SKU: Hydac_RF_Filter_Return Category: Hyd_Filtration_Filters_Return Description Description • RF 30 filters are constructed of polyamide plastic. • RF 60 – 330 filters are constructed of aluminum material. Aluminum alloy is water tolerant – anodization is not required for high water based fluids (HWBF). • RF 660 – 1300 filters are constructed of ductile iron. • Non-welded housing design reduces stress concentrations and prevents fatigue failure. • Inlet/outlet port options include NPT, SAE straight thread O-ring boss, and SAE 4-bolt flange to allow easy installation without costly adapters. • O-ring seals are used to provide positive, reliable sealing. Choice of O-ring materials (nitrile rubber, fluorocarbon elastomer, ethylene propylene rubber) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water base fluids. • Bolt-on lid requires minimal clearance for removal. • Reusable contamination basket prevents loss of retained contaminants into the reservoir during element replacement. • Single piece casting provides rigidity for inline or in-tank mounting.
