GONAL 0525ES converter shape 90° NA100 - 55x110

90o 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 circular cross-section. 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. Characteristics of Gonal Fit&Go system elements: Ventilation element equipped with special rubber seals on the connection surfaces, which can be used to create a system classified in the highest airtightness class ("D" airtightness class!). Its advantages:- Fast and precise fitting;- Can be installed without tools;- Factory-fixed, displacement-proof rubber seal;- The position of the fittings can be changed / fine-tuned afterwards without deteriorating the sealing efficiency;- It does not require the use of other solutions that improve/increase the airtightness;- A leak-free system can be created by using them; - Lower noise level resulting from air flow; - High energy efficiency.
