‘Harmonic Filters’

An Engineeringtalk guide

Start with the news release Parker announces Par<>Fit filter elements from Parker Hannifin - Parker Sales UK, which we summarised at the time by saying "Parker Hannifin has announced a range of competitively priced Parker quality replacement filter elements.". Several months prior to that, we featured the news release Pump Engineering offers aseptic control valve from Pump Engineering: "A compact aseptic control valve suitable for use in critical areas such as bioreactors, pharmaceuticals, biologics and food processing, has been added to the Badger Meter valve range. ".

In June 2009, we covered the news from Atlas Copco Compressors - take a look at Compressors help create snow for ski slope which says: "An authentic ski surface has been created in Hemel Hempstead's new Snow Centre with snow cannon technology that incorporates compressed air delivered by a system from Atlas Copco Compressors. ".

Take a look also at the news release from Cropico, Cropico ohmmeter enhances unit resistance testing, as well as Festo solutions aid Guernsey water treatment plant from Festo, and Sintered mesh filter screen added to range from Axium Process.
