Filter fan units

Snapping into prepared mounting cutouts, Rittal TopTherm filter fan units can be installed, maintained and configured without tools; they are compatible with mounting cutouts of existing Rittal filter fans. Available in capacities from 12 to 424 cu. ft./ min. and a full range of voltages, they have a diagonal fan motor design for pressure stability and constant airflow, even if a filter mat is contaminated.
