Function Producers in every line of trade are constantly in pursuit of ways to downsize their products yet retain the same performance. This is also the case in the indoor climate system field. The smaller the products we at Swegon are able to fabricate; the more installation options the subcontractor will have at his disposal. Reduced sizes also make the products easier to handle and install. It was with these prerequisites in mind that we began to develop the new SORDO, our popular round sound attenuator with circular connection spigots.
