Product Overview
I-656C5 is a mainstream coalescing filter cartridge from Velcon, widely used for hydrocarbon liquid dehydration and impurity removal. Our factory produces fully compatible alternative filters for this model. Consistent dimension, interface and sealing design enable direct replacement without modifying filter housings. Compared with genuine Velcon parts, our replacement version offers much lower prices while maintaining reliable filtration performance for daily industrial operation.
Core Application Scenarios
Aviation fuel system
Airport fuel depots, aircraft refueling equipment, aviation kerosene storage and transportation pipelines to remove moisture and particles and protect aircraft engines.
Oil depot & petrochemical industry
Purification of gasoline, diesel and biodiesel during loading, unloading and storage, oil & gas station condensate filtration.
Industrial lubrication system
Filter turbine oil, transformer oil and hydraulic oil to eliminate emulsified water and avoid equipment rust and valve blockage.
Organic solvent separation
Low-viscosity hydrocarbon solvent liquid-liquid separation, matched with standard Velcon filter separators.

Advantages of Our Low-cost Replacement Cartridge
Full compatibility for direct installation
Identical size and structure as original I-656C5, no extra transformation or accessories needed during replacement.
Cost-effective without performance loss
Factory direct supply removes brand markup. Our filter media reaches OEM-level separation effect, effectively cutting long-term consumable procurement expenses.
