FactoryRegistry lists 605 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced penthouses, shutters, guards, and other parts and accessories for industrial centrifugal, axial, and propeller fans and blowers (excluding power roof ventilators), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
