F50F DUCT MOUNTED ELECTRONIC AIR CLEANER

Determine Duct Design Requirements
The air cleaner is adaptable to all new or existing forced air
heating, cooling and ventilating systems used in residential
applications. Transitions, turning vanes, or offsets may be
needed in some applications for effective operation.
Transitions
Transitions are needed when the duct is a different size than
the air cleaner cabinet. Gradual transitions reduce air
turbulence and increase efficiency. Limit expansion to no
more than 20 degrees or about 4 in. per running foot (100
mm per 300 linear mm) on each side of a transition fitting.
