The Design-Aire SL is our most popular fan-filter unit. The “slim line” housing was designed to accomodate installation in tight ceiling spaces, where our older models and many competing models could not be installed. Our entire series of Design-Aire modules come standard with many beneficial features to suit your specific application.
