S&P FB Series Filter Boxes

FB filter boxes are used when the installation requires filtered air to be introduced, to prevent the entry of dust and impurities to the area being ventilated. They have an easy open cover, in order to quickly change the filtering element.

The FB filter boxes come with a MERV-8 rated filter. Sheet metal construction.
