Only available in the "MULTIFORM" system.
These parts are formed by two tubes or bends of different diameters, one inside another with concentric radii, with an interior of perforated sheet metal and with suitable acoustic insulation placed between the tubes in order to reduce noise transmitted from inside the conducts from fans, air circulation or the movement of materials and particles.
Available in sizes starting from 550mm in diameter, and in varying sizes of weight, size and volume. For safety reasons we recommend fitting these parts to the conduit using M-275 or M-272 flanges and placing them at the outlet of the filter or ventilation unit outlet.
These parts are for general application in ventilation, air-conditioning and air expulsion units and are especially recommended for powder collection and pneumatic transport tube networks for materials and particles.
