The canopy for the FI 1120 industrial cyclone is a structural element used in flue gas desulfurization systems, air purification or industrial processes that require the separation of dust and particulates from the flowing air or gas.Cyclones with a canopy are not designed to work with a filter and there is no possibility of returning air to the production hall. They are readily used for sawdust extraction from unheated rooms and where chips or wet sawdust are transported.
