The CARDEV SDFC filter element, is a depth filter made of long fibre cellulose, with a full diameter polyester protection disc. The element can be used on all oil-based fluids such as hydraulic, engine, gearbox oils and diesel fuels.
CARDEV SDFC Benefits include:
- Removes microparticles
- Removes free and dissolved water contamination
- Increases system reliability
- Prevents system corrosion
- Reduces component wear
- Extends oil life and generates CO2 savings
- Reduces operating costs
- High dirt and water retention capacity

Before And After Using CARDEV Oil Filtration
Removes free and dissolved water down to <50ppm (0.005%).
Without CARDEV Filtration
Not monitoring your oil is more damaging than you think.

Frequently Asked Oil Filtration Questions
Contamination can be broken down into three basic forms – Particulate, Water and Air.
Particulate is generally classified as ‘Silt’ or ‘Chip’. Silt is defined as an accumulation over time of particulates measuring less than 5 microns. The effect of Silt contamination is a slow degradation of system component performance and failure. Chips (measuring more than 5 microns) have a more dramatic effect and can cause immediate, catastrophic, unplanned and costly failures.
There are many areas where contamination can gain access into a hydraulic system, starting from as early as the build process. These include dust, welding slag, rubber from hydraulic hoses/seals, sand from castings, poor cleaning of components, and metal debris from machined components.
Open reservoir filling points, leaking heat exchangers, poor-performing or non-existing reservoir breathers, lack of proper filtration methods and worn cylinder seals are just some of the additional areas contaminants can enter during operation.
Another major source of contamination introduction simply happens when fresh, new, but dirty, contaminated oils are introduced. This can even happen during system top-ups.
The following chart (ISO And NAS Cleanliness Codes) details the ISO code, relevant particle amounts and the type of application and its sensitivity level. More sensitive applications require cleaner oil to ensure reliability.
