Breathers, filter elements for diverse industries

BMG’s fluid technology services include solutions for hydraulics and pneumatics, lubrication, fuel and industrial filtration systems, hydraulic hose and fittings, as well as instrumentation, pumps and industrial valves.
“The range encompasses FG EcoPart filter elements for stationary and mobile hydraulic systems from the Filtration Group. These components, with defined filter performance and purity class, comply with stringent DIN and ISO standards and have all other necessary standard industry approvals,” said David Dyce, business unit manager, Fluid Technology, BMG.
“FG EcoPart series, which includes a wide range of pressure filter and return filter elements, is available from BMG in different versions, with various grades of fineness.”
These components are suitable for diverse hydraulic applications, as well as gear oil treatment. FG Filter elements are designed to reduce the solid particle contamination to the prescribed contamination class, to prevent the ingress of dirt from the environment and maintain the properties of the hydraulics fluid for an extended time period.
Included in this range are FG desiccant breathers, which protect lubricants and machines from damage caused by moisture and the ingress of particles.
The FG breather replaces conventional dust caps or breathers often found on new equipment. When contaminated air enters the top of the breather, it passes through layered filter media, blocking particles from entering the breather, thus preventing wear to equipment surfaces.
The filtered air passes through a bed of silica gel, which effectively removes moisture. Silica keeps the equipment dry by attracting moisture from inside the equipment reservoir during service or shut-down.
FG desiccant breathers have an enlarged housing, which ensures up to 20% more absorption of moisture than conventional breathers. The centre tube is constructed from a robust nylon material, providing rigidity to the element and allowing an even air flow through the silica gel. For additional system protection, secondary filter media prevent any possible migration of silica dust.
For optimum change-out intervals, a clear polycarbonate outer-shell provides a visual indicator of the condition of silica gel. Multi-layer polyester filter media provide 3-micron particulate filtration and a polyurethane foam collects oil mist and distributes air evenly over filter media and the moisture-absorbing silica gel.
Breathers are suitable for use in hydraulic units, where there are high humidity and temperature fluctuations. The normal hazards of condensation - rapid ageing of hydraulic oil, degradation of additives and corrosion - are prevented.
Typical applications include wind energy, power plants, tunnel construction, aerospace and manufacturing processes, as well as petrochemical and chemical plants.
In addition, BMG supplies FG coalescer filters, which are used in the fuel line for the efficient operation of marine diesel engines.
The company’s national branch network, of over 130 outlets, supports an extensive range of fluid technology products and bespoke systems, with field services and technical resources. BMG also offers a design and manufacturing service, according to exact requirements, for small installations and major projects alike.
