Greenheck has introduced a new single width fan, Model CSW, for general ventilation as well as environments which require spark resistance, high temperature tolerance, or resistance to corrosive elements. Model CSW is available in six direct-drive and belt-drive arrangements and features quad-split housings as well as a new Class 0 design for low pressure applications. Belt-drive units include an improved motor plate adjustment for easy belt tensioning. In addition, an increased motor size is available on Model CSW Arrangements 9 and 10. Arrangement 10 is available with a motor cover; all other arrangements can be specified with weather hoods.

Model CSW, replaces Greenheck Models BISW and AFSW. Currently available in fan sizes 33 – 73 inches. Sizes 7 – 30 inches will be available in August 2014. You can find complete submittal and base drawings in CAPS for all arrangements.
