AAF's Universal Holding Frames can be used individually or may be combined to fit virtually any size filter bank. Made with the same high quality and durability as the galvanized steel frame, this model is constructed with 18-gauge stainless steel for corrosion resistance and longer service life. All frames feature holes on each side for bolting or riveting into filter banks. The 3” deep (nominal) frame will support all standard combinations of pre and final filters. Factory installed EPDM gaskets ensure a proper seal between the frame and filter to minimize dirty air bypass (all standard sizes are also available ungasketed).
Stainless Steel UHF's are designed to use only the Knock-On style holding latches. Six standard sizes are available (WxH): 24 x 24, 20 x 25, 20 x 20, 16 x 25, 16 x 20, and 12 x 24.
