Technical details 2.1. Housing All fan housings from size 7 to 40 are manufactured in galvanized sheet steel (Fig. 1). From sizes 7 to 18, the fan sideplates are spot welded to the scroll housing (Fig. 2). The inlet cones are manufactured in galvanized sheet steel and are part of the housing sideplates. A series of standard holes are located on the sideplates to allow the installation of frames or mounting base. These holes are positioned in such a way that several standard accessories can be attached with the necessary fixing screws. 2.2. Impeller The impeller is manufactured in galvanized sheet steel with tab locked blades, (Fig. 4). All wheels are balanced, both statically and dynamically, to an accuracy grade of G = 6.3 in accordance to DIN ISO 1940-1 and ANSI S2.19 – 1989. All the impellers from size 7-7 to 40-40 are secured to the shaft via a hub. The hub bore is precision machined and incorporates a keyway and locking screw. 2.3. Shafts All shafts are designed with a high safety factor and with the first critical speed well in excess of the maximum fan speed. Made with hardened steel, the shafts are precision ground and polished, and includes keyways for the wheel hub and sheaves. All shafts are coated with a protective paint for added corrosion protection prior to shipping. 2.4. Bearings Bearings mounted in a rubber interliner, which in turn, fits in a sturdy three-arm or four-arm spider bracket (Fig. 5). These bearings are permanently lubricated and sealed for the life time of the fan.
