GONAL 0625 converter shape 90° NA100 - 60x120

90o FLAT DUCT CONVERTER: A converting element that can be placed between the start and end points of an air-conditioning system, for connecting flat ducts and air-conditioning pipes with a circular cross-section. The system can be more easily covered/hidden by using air ducts with a rectangular cross-section and the corresponding fittings. It has a smaller "thickness" size compared to the elements of the equivalent "traditional" pipe system with a round cross-section, so it can be used in narrower places (e.g. above false ceilings, behind floor beams) ) can also be placed without reducing (narrowing) the useful cross-section. Restrictions used in the ventilation system can result in higher pressure loss and noise from higher air flow.
