Working toards perfection The RDY series This fan range employs housings ith square-shaped outlet and sizes from the R20 normal number series, in accordance to AMCA Standard 99-0098 76 and to DIN 323. The RDY range is made of high efficiency, double idth, double inlet centrifugal fans ith backard inclined blades. Volume flo rate from m³/h to 150.000 m³/h Total pressure up to 3.500. Construction versions RDY fans are available in the folloing versions: Version L R K K1 K2 Sizes 01/-0560 01/-0710 0200/-0 0315/-0900 0500/-0 Tin fan versions Where a limited fan height is required, RDY fans are available also in double or tin fan versions, ith to double inlet impellers on a common shaft, supported by three or four bearings. These versions are identified by the G2 prefix. Double fans are available in the folloing sizes: Version G2K G2K2 Sizes 0250/-0 0250/-0 Construction Specifications The construction standard used for Nicotra Gebhardt RDY fans is inspired to the maximum strength and reliability, independently from the construction version. Common characteristics of these products are: - product quality - high performance - outmost economy - quietness - ease of assembly Scrolls All the scrolls are made ith hot dip galvanised steel EN 10142. No electrical spot elding is used as the scroll back is joined to the side plates ith the Pittsbourgh lock forming system. This prevents any oxidation starting from the elding spots. Attachment points on the side plates Standard holes in the side plates are used to attach mounting feet or side frames to create different versions. Up to size 400, self-threading scres are used, hile all the larger sizes have captive nuts for use ith M10 scres. Impellers RDY impellers, starting from size 250, have 11 specially-designed, backard inclined blades. Built from mild steel, they are elded, treated and painted ith alchidicmelamminic paint RAL 7030. The smaller fan sizes (1...225) have 8 bladed, backard curved impellers, made ith Glassfibre Reinforced Polyamide. RDY impellers are statically and dynamically balanced according to ISO 1940 ith grade G4. Side frames Light-construction side frames of the R versions are made ith cold-formed, galvanised steel Sendzimir type EN 10142. Heavy-duty side frames of the K, K1, K2, G2K and G2K2 versions are made ith hot-rolled steel sections, elded and coated ith alchidic-melamminic paint RAL 7030. As an option, they can be protected ith hot dip galvanising. Shafts Manufactured from precision ground, C45 carbon steel bars, using precision tools to cut keyays. All the shafts are coated, after assembly, ith a clearly distinguishable, bright yello protective paint. Stainless steel shafts can be provided on request, ith an appropriate reduction of the maximum operating speed. Shaft diameters are selected to achieve a safety factor for critical speed 1.25 higher than the maximum operating speed.. 4

These coefficients are given on three different similarity curves and at three different operating speeds. Those coefficients marked ith SX apply to operating points located on the left border of the normal operating area (blue diagonal line on the left). The coefficients marked ith DX apply to operating points located on the right border of the normal operating area (blue diagonal line on the right). Those coefficients marked ith EtaTMax apply to operating points located on the maximum efficiency operating line. It is preferable to interpolate beteen the listed coefficients hen referring to the operating points beteen the listed speeds or operating lines. The Ventil selection program applies the complete calculation procedure, in accordance ith BS 848 rt 2, Appendix G, and provides easily the best approximation of the results. 7
