The second design element is the bore size of the thread section and the tailpipe, if used. Orthos commonly selects amongst four constructions, though more are available. In increasing pressure drop for a given flow rate, bore diameters of 21mm, 16mm, 16mm with a 13mm restriction in the thread section, and also 13mm may be utilized. To add even more pressure drop, a closed stem with holes may be used—7 hole sizes are available.
ORTHOS engineering staff will select the correct nozzle construction combination to optimize performance for your specific application. Proper nozzle characteristics ensure media retention, negate fouling, and produce excellent distribution, which all will deliver optimal filter performance.
