AT SC 7/7-18/18 AT C 7/7-18/18 Specifications Fan data Fittings / Accessories Belt Driven Centrifugal Fans / AT / Specifications High performance centrifugal fan AT SC and AT C Double width double inlet (DWDI) belt driven fan, with forward curved blades. Lap-jointed scroll of galvanized steel EN 10142 assembled through 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. Construction with two side frames, made of cold-formed galvanized steel angular sections welded to the side plates, for a better strength and stiffness of the fan structure. Single row, deep groove, self-aligning ball bearings, lubricated and sealed for life, with eccentric collar locking. Bearings are mounted inside conductive rubber vibration absorbers on bearing supporting spiders. It can be easily installed in four different positions. Discharge flange on request. Where an even better mechanical strength is required, e.g. when the fan itself is used as a stiffening element of the base frame, a further reinforced version is available. It is identified by the letter C. This version is available in the same sizes as the SC version, with the same dimensions and the same performance limits. With the addition of three steel bars, welded between three corners of the side frames, the frames of these fans are joined to form a closed, box-like supporting structure. For sizes from 7/7 to 10/10, in addition to the standard construction version with flats on shaft ends (“type 1”), it is also available a version with keyways (“type 2”). Shaft ends of larger sizes are only of “Type 2”.
