Healthy Filtration

AN INNOVATIVE NEW BRITISH TECHNOLOGY FOR THE REMOVAL OF WATER FROM OIL AND FUEL

Filtertechnik has taken water absorbency to the next level with Filtasorb 2 which can hold twice the volume of water than the previous version and 3 times as much as its nearest competitor. In a demanding trial, using diesel at a flow rate of 150 l/min, Filtasorb 2 removed 6 litres of free and absorbed water to bring the water content to under 100ppm in a single pass from an initial level of over 44,000ppm!

Oil degradation leading to oxidation, sludge and varnish

Oil degradation is a common problem in industrial, agricultural and construction equipment. Oxidation forms sludge which is the precursor to a deposit referred to as ‘varnish’. When oil degrades due to high temperatures, water or chemical contamination the functional properties of the oil are changed. Harmful products form in the oil including: • acids •…

HH recommended system sampling frequency chart

We are often asked “at what frequency should I sample oil?” As a broad guide the table above can be used. If problems are suspected or if a machine is ‘mission critical’ then more frequent sampling is a sensible precaution! In all sampling situations it is vital that the machine is in operation or has…

Principles of filtration

Introduction: Filters are very important in industrial applications and they are essential in the operation of internal combustion engines and hydraulic circuits. Filtration Definition: • Separation of particles from a fluid (liquid or gas) by the passage of that fluid through a permeable medium/membrane • When particles are high in value this is known as…

The perils of water in hydraulic oil

Water may be life giving to humans, animals and vegetation but water in hydraulic oil or fuel can do severe harm to a machine’s system.
Water can be trapped in hydraulic oil in 3 states:
• Dissolved: not visible
• Entrained: Visible and milky
• Free: visible as water
