GONAL SU-2040 converter shape NA150 - 90x180

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 round cross-section. By using air-conditioning ducts with a rectangular cross-section and the corresponding fittings, the system can be more easily covered/hidden. The equivalent "traditional" " has a smaller "thickness" size compared to the elements of a pipe system with a round cross-section, so it can also 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.
