42 Clean working practises
Clean working practises
The majority of hydraulic systems require cleanliness which controls below
around a 40 micron threshold (beyond the limit of human eyesight). When
analysing particles down to levels of 4um, 6um & 14um you are talking about
objects of a cellular/bacterial size. This creates various challenges, and is
starting to drive better and cleaner working practices in industry. Our prod-
ucts are at the forefront of this challenge, and will help you to manage the
quality and productivity of your systems.
Do’s
− Do use filter breathers on tank tops.
− Do use tank designs, which are self draining (sloped or conical).
− Do use tanks which can be sealed off from the surrounding environment.
− Do exercise care and use funnels when filling tanks with fluid.
− Do utilize stainless steel and methods such as electro-polishing in the
design of system components upstream of your first filter set.
− Do perform off-line analysis in a controlled environment such as a labo-
ratory which should contain fewer airborne contaminants that where the
sample was taken from.
− Do use suitable, glass bottles (ideally certified clean) to take samples,
along with a hand pump to reduce contamination ingress.
− Do filter your system thoroughly before using it in your production process.
