Tightness of the air duct system is a planning specification
According to the strict conditions of the VDI 6022 the planner of a construction project is obligated to largely ensure a leakage-free AC system. The used ducts and their connection account for a large portion for the tightness of the ventilation system. VENTAFLEX air ducts and the connecting VentaSnap clamps cleary have demonstrably 83% less air loss than defined in the recommended minimum requirement of class C.
TÜV-tested quality of VENTAFLEX
Before marketing VENTAFLEX products have to go through extensives tests. After passing different in-house test procedures independant institutes are assigned to test the air ducts for highest quality standards. TÜV Nord confirms the extraordinary tightness of the VENTAFLEX air duct system in its reports.
