GONAL SU-2002/15 flat channel 90x180 L=1500

FLAT DUCT: A straight element that can be placed between the start and end points of an air engineering system. With its application, the ventilation connection of the system can be more easily covered/hidden. It has a smaller "thickness" size compared to the equivalent "traditional" 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. 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.
