Heavyduty SKF or similar self aligning ball or roller type bearings are used asstandard. Fans are supplied with powder coat finish as standard.TestingRated fan performance has been tested in accordance with therequirements of AMCA Standard 210. Rated fan sound performance hasbeen tested in accordance with the requirements of AMCA Standard 300.SelectionThe quick selection chart (opposite page) enable the selection of the mostefficient fan for a given duty. To determine the most efficient fan size, locatethe intersection of the required volume (m 3 /s) and static pressure (Pascals) onthe graph. The size to the right of this point is the correct selection.Ancillary Equipment♦♦♦♦♦♦Variable Speed DriveInlet guardSpark resistant constructionVibration isolatorsStainless steel or aluminium constructionSpecial paint and coatings© Fans Direct 2011 www.fansdirect.com.au Tel.
