GONAL 0826 converter shape 90° NA120 - 75x150

90° FLAT DUCT CONVERTER: A converting element that can be placed between the start and end points of an air-conditioning system, for connecting a flat duct and an air-conditioning pipe with a circular cross-section. The system can be more easily covered/hidden by using air-conditioning ducts with a rectangular cross-section and the corresponding fittings. it has a smaller "thickness" size compared to the elements of an equivalent "traditional" circular cross-section pipe system, so it can be placed in narrower places (e.g. above false ceilings, behind floor beams) 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.
