APPLICATION
The CJC™ Gear Filter insert, GFi 27/27 is specially designedfor filtration and flushing of wind turbine gears. The CJC™GFi 27/27 has a high capacity for submicron particles and isdocumented to remove considerable amounts of particlesdown to the size of 0.1 microns.
The filter insert is optimized for high performance in:
air-containing oil
variable temperature conditions
used oil
This filter insert is applicable for viscosities in the range ISOVG 320-480 cSt.
FILTRATION CAPABILITY
Particle Removal
The CJC™ GFi 27/27 has been designed for efficient removalof both hard and soft particles. Particles above approx.>1 microns are removed by mechanical filtration,smaller particles <1 micron are removed primarily bymeans of Van der Waal forces and electrochemical forces.
Filtration degree:
21 μm absolute: >99.9 % of all solid particles > 21 μm
6 μm absolute: >99.5 % of all solid particles > 6 μm
4 μm absolute: >99.0 % of all solid particles > 4 μm
2 μm absolute: >80.0 % of all solid particles > 2 μm
1 μm absolute: >50.0 % of all solid particles > 1 μm
0.1 μm absolute: >10.0 % of all solid particles >0.1 μm
Degradation Products
Oxidation by-products, resin/sludge, used additives andwax formations are retained by the cellulose material.The cellulose will absorb and adsorb up to approx. 1 kgof soluble oxidation products. Used wind turbine oil willtypically contain a small amount of highly catalytically activeatomic iron (Fe). The CJC™ cellulose combination hasbeen documented by ICP analysis to effectively reduce theamount of free iron in oil.
Water Removal
The CJC™ GFi 27/27 will remove large amounts of freewater if present in the oil, in documented cases up to 4000ml of water. Please refer to the CJC™ Water/Cellulose/Oil Equilibrium datasheet for specification of the removalcapacity of dissolved water.
DIMENSIONS
The figures below are nominal:
Diameter: 27 cm (10.6”)
Height: 27 cm (10.6”)
COMPONENT
The CJC™ GFi 27/27 consist of bonded double discs consistingof 4 different types of cellulose fibres. Each type of fiberperforms a special function in terms of filtration and conditioningof the oil. Due to the large internal surface area ofthe cellulosic fibers the CJC™ GFi 27/27 has the capability ofacting as a free radical scavenger thus reducing the degradationrate of the oil.
