It is hard to overestimate the cleanliness . Especially nowadays, when alarms go off about air full of pollution like particle matter, hydrocarbons or Carbon and Sulphur oxides.
In a standard ventilation system, there are many vibrations and noises which are transmitted in the metal ducts, generated by air handling units - fans, heat recovery units, and chillers. A properly installed ventilation ductwork should have built-in components to counteract the transmission of these vibrations or significantly isolate and dampen them.
Easy, quick and precise installation of ducts even in hard to reach places is the main advantage of the STRUT support system. The available selection of mounting accessories make for a fully professional fixing system.
The PWQ-R flange cleat is used for joining rectangular ducts. A channel of particular length is slid on PQ-20 or PQ-30 duct frame profiles. Bent edges provide an easy way to slide and hammer the channel. SAVE time and room!
ErP, that is, ”Energy related Products” means products related to energy. In order to accomplish the objectives of the EU Climate and Energy Package the EuP directive - “Energy-Using Products” was issued in 2005, which was thereafter replaced by the ErP directive in 2009.
