The CARDEV 2S offline filter system removes water and particle contamination for most oils, leaving them “Cleaner Than New”. Oil can be filtered whilst machinery is running, when machinery is stopped, and even when the oil is removed from the machinery. With your machinery always running with extremely clean oil it becomes more reliable and more efficient, with lifetime operating costs dropping dramatically. Oil drain extensions (alongside condition monitoring) create further environmental and cost benefits.
Supplied with 2x SDFC Filter Element.

Not monitoring your oil is more damaging than you think.
With CARDEV Filtration
Within 1 week of installing a CARDEV Filtration system, you will notice a significant improvement with your machine.
In order to achieve optimum cleanliness, it is necessary to process a system’s volume through the system up to 5 times. Flow through the system is dependent on several factors. The grade of the oil, its temperature, base oil technology and contamination levels all have the potential to change the flow rate that can be achieved, and therefore the time required to reach optimum cleanliness.
As a guide please refer to the table below:
|100 Litre System||250 Litre System||500 Litre System||1000 Litre System|
|ISO VG46 HLP @40°C||2 hr||5 hr||10 hr||20 hr|
Note: Flow rates, oil cleanliness levels and moisture removal results are based on ISO VG 46 Mineral Oil @ 40°C

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.
