Kleenoil removes all particulate less than 3 micron absolute at 99% efficiency - single pass.
.... and to 1 micron relative on a multipass.
as shown in the independant Beta rating test.
INDEPENDENT TEST TO ATTAIN KLEENOILS FILTRATION CAPABILITY OF CLEANSING PARTICULATE FROM HYDRAULIC FLUID.
ISO Cleanliness Code 4406:1999
The International Organization for Standardization created the cleanliness code 4406:1999 to quantify particulate contamination levels per millilitre of fluid at three sizes: 4µ[c], 6µ[c], and 14µ[c]. This ISO code is expressed in 3 numbers: 19/17/14. Each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger.
It is important to note that each time a code increases the quantity range of particles doubles.
The results are quite defined in showing the progression of cleansing removing the particulate sizes effectively within a 6 hour period on 120ltr hydraulic fluid.
Applying this online in machines/hydraulic systems offers a faster timescale in cleansing, and then maintains constant hygiene.
