Smooth and protrusion-free inner duct surfaces. Hygienic, dirt-retardant and easy to clean. Energy-efficient air-flow through less friction, turbulences, and pressure drops.
and easy to assemble !
Especially designed connection components with integrated gasket (SRX Joining Clips and MUX Overollars) allow an efficient and rapid assembly. Only one screw per connection for all Ø from 80 to 1000 mm! The parts are light, easy to handle and, because of the formed-on flange, exceptionally sturdy. Possibility to dismantle each piece (retrofitting).
