The new ISO 12500 standard, covers the testing of compressed air filters and to provide a proven and tested basis to evaluate performance. This is a great improvement over the past where one could simply make claims about what a compressed air filter really can do while not having a standard to back it up.
A new product called the Expel 30 marketed by Tech Sales Co. in the USA and Canada as well as by Nex Flow Air Products is a new type of filter that works on a separation principle, with no filter cartridges to replace, and can guarantee filtration to 1micron, and 99.9999 percent removal of liquid (water and oil) which is significant. This new design works for flow of 4 to 20 SCFM. Other sizes (larger and smaller) are to be available in the next several months. There have been filters for some time that work on the separation principle but without the ISO 12500 testing so claims could not be guaranteed. This makes the new EXPEL30 unique in many ways in addition to its quality design and manufacture, ease of dismantling and reassembly, and its low pressure drop. It was designed using computational flow dynamics from the ground up to assure ISO 12500 compliance and has several patent pending features.
Ideal for point of use applications where water, oil and particulate (down to 1 micron) is hard to control or where cartridge filters require consistent replacement at considerable cost. It even has a 5 year manufacturers warranty.
Something definitely worth looking into…..
