AT AR 9/7-18/18 Specifications Fan data Fittings / Accessories 102 High performance centrifugal fan AT AR Double width double inlet (DWDI) belt driven fan, with forward curved blades. Lap-jointed scroll of galvanized steel EN 10142 assembled with roller-lock seaming. Straight cut off plate at fan outlet. Impeller with forward curved blades of galvanized steel EN 10142, statically and dynamically balanced to grade G4, according to UNI ISO 1940. For applications requiring even higher installed power, or where there is a requirement for re-lubricatable bearings, the AR version is the correct solution. The reinforced side-frames are made of galvanized steel sections, welded to the sides of the scroll and joined together in three corners. Single row, deep groove, self-aligning ball bearings, re-lubricatable and reinforced, with eccentric collar locking. Bearings are mounted inside a single-piece cast iron pillow block. It can be easily installed in four different positions. Discharge flange on request.
