nVent Hoffman: HN 3R Side-Mount Filter Fans
Introducing the HN 3R Side-Mount Filter Fans from nVent Hoffman. HN 3R Side-Mount Filter Fans quickly install into enclosures with a click-fit design; no tools or screws required, and the grilles open with the flick of a finger for easy filter replacement. There is a reverse airflow option on items ending with “R” available to push/pull air through higher static pressure, and a standard rope gasket provides a proper seal to the enclosure, as well as similar cut-out sizes as other filter fan manufacturers.
