Universal Holding Frames

Flexible Design

AAF Universal Holding Frames can be used individually, or may be combined to fit virtually any size filter bank. The frames are available in galvanised steel or stainless steel. All frames feature holes on each side for bolting or riveting into filter banks. The 75 mm deep (nominal) frame will support all standard combinations of pre- and final filters. 

High Performance in Tough Operating Conditions

The galvanised steel frames have factory-installed gaskets to ensure a proper seal between the frame and filter and minimise dirty air by-pass (all standard sizes are also available without gaskets). The frames also offer increased resistance to corrosion and longer service life in corrosive environments. They are available with factory-installed EPDM gaskets (all standard sizes are also available without gaskets).

Reliable High Temperature Operation

The aluminized steel holding frame is designed for high temperature applications. When constructed without a gasket, the aluminized frame will tolerate temperatures up to 900°F, making it ideal in filtration systems for paint-curing ovens. The aluminized steel frame is also available with factory-installed EPDM gaskets.

The Universal Holding Frames are designed to use either the Universal Holding Latches or the Knock-on style holding latches. Seven standard sizes are available (WxH): 24 x 24, 20 x 25, 20 x 20, 16 x 25, 16 x 20, 20 x 24, and 12 x 24.
