Product Application
Our APGFB return grille is constructed of aluminum. Why? Not only is aluminum a lightweight metal which makes installation and maintenance easy, but it is also resistant to corrosion. This makes APGFB grilles a popular choice for rooms that have high humidity or corrosive environment. The filter back ensures that the particulate matter does not return to the ventilation systems and the perforated face provides optimum air distribution. They are ideal for most ceiling applications and can be installed in hospitals and laboratories.
