3 Generl LindRekt LindRekt consists of rectngulr ducts, fittings nd silencers with dimensions in ccordnce with SS-EN 1505 when not otherwise specified. All fittings nd ducts re mde of hot-dip glvnized sheet steel, Z 275. If higher corrosion protection is needed, lu-zinc or stinless steel cn e used. A joining profile is mounted t the end of every fitting nd duct. Self-tpping screws re only needed on insulted ducts, to fix the insultion rils. The screws re then conceled in the insultion, out of hrm s wy. A coon guide moulding, LS3 nd two sel mouldings, LS31 or LS21 re needed to join components. So precut mouldings nd n dequte length of sel moulding re supplied in ech delivery. Sels re mde from temperture resistnt polythene. Recoended temperture rnge is -70 to +80 C. Support distnces of ducts nd components must never exceed 2400 for ny dimension. Nor my there e more thn one joint etween two supports. Non-stndrd ducts nd duct components cn e tendered on request. Plese enclose dimensioned sketch if possile. Tightness Ducts nd fittings mintin tightness clss C. This only pplies on condition tht the products re instlled in ccordnce with the instlltion instruction. Plese refer to pge for more informtion out seling clsses nd offucuk requirements. Strength Stndrd ducts nd duct components cn withstnd positive nd negtive pressures of 1000 P. Lrger ducts nd fittings re reinforced y U-shped profiles nd integrted corner joints.
