Compact compressed air filters reduce energy use
PARKER domnick hunter has developed a range of compact compressed air filters said to have efficient operation to reduce energy usage, produce cleaner air output and reduce equipment damage.
Inefficient compressed air systems have to work harder to push air through. If the equipment produces dirty output, factory operators can be liable for occupational health and safety complaints as well as damage to tools and production.
The Oil-X Evolution range of compressed air filters were designed from the ground up, with a focus on air flow management, filtration media selection and the efficient removal of coalesced liquid.
According to the engineers, the filters are designed to eliminate all unnecessary pressure losses. A ‘bell mouth’ within the inlet port reduces the level of turbulent air flow entering the housing of the machine.
A radius blended bend is used to minimise turbulence from the turning air, while turning vanes split the corner into a number of smaller and more efficient corners. The air is then evenly distributed throughout the filter element for maximum filtration performance.
The filter elements in the Oil-X systems are said to differ from standard filters, which soak up oil and water and run in a saturated state. Saturated running can block air flow, reducing pressure.
The borosilicate glass nanofibre filtration media used in the systems have an oleophobic coating which repels oil and water, while trapping dirt. It uses two filter media layers, with a coarser layer preventing premature blockage of the finer layer.
