Keep hydraulic oil "as new" with virtually unlimited life
Keep hydraulic oil "as new" with virtually unlimited lifeKeywords: Hydraulics, Oil
The prospect of hydraulic oil being kept permanently in an "as new" condition, with a substantial increase in equipment response times, and up to a ten-fold increase in component life, is what is claimed for the Kleenoil by-pass filtration system (Plate 5).
More than 70 percent of hydraulic failures on machine tools, cranes, construction plant, public service and local authority vehicles, and many other general engineering or production oriented machines can be attributed to contaminants in oil. An abrasive particle within a system quickly abrades further particles which agglomerate into a mass of wear catalysts. Smaller particles become silt which coats metal surfaces, clogs oil flows and causes sticking components. This can result in power losses of 15-20 percent, leading to slower response times from equipment, premature wear and eventual plant failure. Standard fitment in-line filters do not remove the silt (which includes particles below 15 microns), and do not remove water or acid residues from hydraulic lines.

High performance hydraulic by-pass filter from Kleenoil Filtration Ltd,
which maintains oil quality, increases performance, reduces breakdowns and
extends equipment life
The Kleenoil filter is a bolt-on product fitted as a by-pass unit to hydraulic systems, compressors or any oil line operating at pressures up to 3,000psi. A built in compensating flow valve controls flow to approximately 4 litres/min at 40psi. At this level it has negligible effect on "system pressure" but is sufficient to maintain the oil in optimum "as new" condition.
The filter media comprises densely packed cellulose tissue, which retains solid particles to below 1 micron in size as well as water, acids and other harmful contaminants. It purifies and permanently maintains oil at a cleanliness level of NAS 1638 class 6, equivalent ISO 14/9 or better, which in real terms is significantly superior to even brand new oil.
The life of the filter element depends on operating conditions but it is recommended that elements are changed four to six times per annum. Capital investment pay-back can be achieved within a very short time, while the elimination of costs for dirty oil replacement and disposal, combined with increased performance, reduced breakdowns and extended operating life are permanent ongoing advantages.
