Multiple layers of expanded Galvanized Steel, enclosed in a heavy weight Galvanized Steel frame. Designed for air applications such as make up air roof top units in industrial, commercial, schools, and office buildings where a heavy weight washable 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.
