AAF Flanders’ Perma Frame is used to mount ducted or fan-powered terminal modules in a hard ceiling application, such as sheet rock or plasterboard. The Perma Frame is ideal for biotech facilities that require frequent wash-down of the cleanroom, as well as isolation hospital rooms where HEPA-type filtration is frequently required.


Perma Frames are manufactured of 18-gauge steel and are welded on all exposed corners to guarantee a smooth cleanable surface. They are finished with a white powdercoat paint as standard. Predrilled mounting holes are furnished on the vertical flanges to facilitate an easy and level installation.
