Roof base B/I 160 antistatic laminate UNIWERSAL44

Roof bases are made of polyester-glass laminate (laminate in the color of the fan) for the standard, acid-resistant and explosion-proof variants, as well as of steel in traditional execution. In the case of steel bases, the surfaces are galvanized with a layer of zinc. It is possible to paint in the color required with powder paints. The bases are made in variants B/I, B/II (base with a ventilation duct) and B/III (base with a ventilation duct). We offer dampers in the adjustable variants (we recommend the installation variant with the BELIMO electric actuator) or inertial, opened by means of an air draft while the fan is running, and automatically closing when it is turned off. The L dimension in the bases type B/II is the length of the ventilation duct directly screwed to the base
