Standard Economizer / Aluminum Filters
Our most popular aluminum filter. It consists of multiple layers of aluminum expanded material, assembled in alternating layers to assure maximum filtering and internal loading capabilities. The media is enclosed in a medium weight aluminum frame, mitered and secured at one corner by rivets. The filter is designed for applications such as light industrial, commercial, schools, and office buildings where a lightweight permanent filter is recommended.
They can also be used as pre filters, which would remove large particles that easily clog a filter. Pre filters keep the main filter lasting longer and the unit running more smoothly. Available in both stock and special sizes. Available in 3″ and 4″ thicknesses.
