45o FLAT DUCT ELEMENT: A 45o element that can be placed between the start and end points of an air technology system, for connecting flat ducts at an angle (miter). 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.
