4 Working oards perfecion The DY series This fan range employs housings ih square-shaped oule and sies from he R0 normal number series, in accordance o Sandard and o ISO The DY range is made of double idh, double inle cenrifugal fans. Volume flo rae from 450 m³/h o m³/h Toal pressure up o a. onsrucion versions DY fans are available in he folloing versions: Version R K K1 K Sies 01/ / /-0 03/ /-0 Tin fan versions Where a limied fan heigh is required, DY fans are available also in double or in fan versions, ih o double inle impellers on a common shaf, suppored by hree or four bearings. These versions are idenified by he prefix. Double fans are available in he folloing sies: Version R K K Sies 01/-0 01/ /-0 050/-0 onsrucion Specificaions The consrucion sandard used for Nicora ebhard DY fans is inspired o he maximum srengh and reliabiliy, independenly from he consrucion version. ommon characerisics of hese producs are: - produc qualiy - high performance - oumos economy - quieness - ease of assembly Scrolls ll he scrolls are made ih ho dip galvanised seel N No elecrical spo elding is used as he scroll back is joined o he side plaes ih he isbourgh lock forming sysem. This prevens any oxidaion saring from he elding spos. achmen poins on he side plaes Sandard holes in he side plaes are used o aach mouning fee or side frames o creae differen versions. Up o sie, self-hreading scres are used, hile all he larger sies have capive nus for use ih 10 scres. Impellers DY impellers have specially-designed Tab-lock forard curved blades, buil from cold-formed, galvanised seel Sendimir. DY impellers are saically and dynamically balanced according o ISO 1940 ih grade 4. Side frames igh-consrucion side frames of he R and R versions are made ih coldformed, galvanised seel Sendimir ype N Heavy-duy side frames of he K, K1, K, K and K versions are made ih ho-rolled seel secions, elded and coaed ih alchidic-melamminic pain R 0. s an opion, hey can be proeced ih ho dip galvanising. Shafs anufacured from precision ground, 45 carbon seel bars, using precision ools o cu keyays. ll he shafs are coaed, afer assembly, ih a clearly disinguishable, brigh yello proecive pain. Sainless seel shafs can be provided on reques. Shaf diameers are seleced o achieve a safey facor for criical speed 1.5 higher han he maximum operaing speed. 4
