Abstract
Methods, devices, systems and apparatus of fully knock-down drum fans that can be shipped completely unassembled so that the smallest packaging is used resulting in more units per container and a lower shipping cost per unit. This allows overseas manufacturers to be more competitive with local manufactures. This is achieved through a drum fan design that utilizes completely modular components that can be assembled quickly and easily either by the distributor of the drum fan or the final end user. A drum fan can include a plural identical shroud curved members, with the same number of pie shaped front grill members, and the same number of pie shaped rear grill members, as well as other modular components that are both easy to nest, pack, store and ship with one another. The knock-down fan will significantly reduce packaging size from approximately 50 to approximately 75% less than current drum fans. The knock-down fan is easy to re-assemble, because of modular components, and the knock-down fan size can be applied to any size drum fan from approximately 24″, 36″, and 42″ up to approximately 60″ in diameter.
