FLAT DUCT CONNECTOR / COUPLER: A connecting element that can be placed between the start and end points of an air technology system, for connecting flat ducts to each other. 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. The constrictions used in the ventilation system can result in greater pressure loss and higher noise from air flow. If the device to be installed has a connection with a circular cross-section, the so-called to one of the "transformer" adapters, which of course can also be found among the air technology accessories, within all size categories.
