Segmented bends with gaskets Description Segmented bend are designed for building ventilation systems based on SPIRAL ducts and plain ducts. They are made of 4 segments; bends in diameters of DN 1120 mm and greater are composed of 5 segments. The segments are fastened by hemming and seaming. The inside surface of the hemmed seams is sealed, and as a result of the double EPDM gaskets, this solution provides air tightness class D according to EN 12237 for ventilation and recuperation systems. The piece is connected with a duct by inserting one into the other. The pieces can be made of 1.4404 stainless steel sheet for ventilation systems in swimming pools. Available materials — Product code example BSL-... -90 — galvanized steel sheet BSL-K-... -90 — 1.4301/304 stainless steel sheet BSL-K-... -90-316L — 1.4404/316L stainless steel sheet, molybdenum-enriched BSL-A-...-90 — AW-1050A H24 aluminium sheet Product code example Product code: BSL - aaa - 90 Volumetric flow rate q Round ducts and fittings ALNOR® ventilation systems is a registered trademark protected by a technical patent.
