Description
GOOD FILTER COMPANY 3/32″, 1/8″, 1/4″, 5/16″ and 3/8″ thick standard duty expanded aluminum filters are constructed of individual layers of heavy duty expanded aluminum and assembled in a “crisscross” pattern. The expansion openings are diamond shaped and each subsequent layer has the diamonds placed in the opposite direction as the previous layer for more efficiency at capturing particulates. There is also at least 1 layer of filter screen wire in the center of the filter. Depending upon the thickness of the filter, some of the expanded aluminum layers are corrugated or flattened in order to completely fill the frame of the filter and increase efficiency.
These filters have various uses including as barrier filters for insects, rodents and larger particulates. Air resistance is less than metal mesh filters but so is efficiency. They are however, almost indestructible and very easy to clean. Used mostly for capturing larger particulates in industrial and commercial applications. Standard duty expanded metal filters are made of heavy duty expanded aluminum with a heavy duty aluminum frame. They come in custom sizes up to 2000 square inches.
