Filter Size Guide

ADD Filtration Synthetic Bag Filters are sized Height x Width x Depth.

For example, a 24 x 12 x 12" (592 x 287 x 300 mm) Bag Filter would have a height of 592 mm, a width of 287 mm and a depth of 300mm, whereas a 12 x 24 x 12" (287 x 592 x 300 mm) Bag Filter would have a height of 287 mm, a width of 592 mm and a depth of 300 mm.

It is important to get the orientation correct because, as the illustration shows, for correct installation the pockets should stand vertically.

All our Glass Panel Filters, Pleated Panel Filters & Bag Filters are sized in millimetre depths & face dimensions. These are sized to suit industry standard sized holding frames, i.e. a 592 x 592 x 45 mm (+5 mm / -0) panel filter is sized to fit into a 24 x 24 x 2" (610 x 610 x 51 mm) holding frame. The filter sizes are smaller to allow the filter fitting with holding clips. This is normal & all manufacturers provide filters smaller than holding frames. For example, 24 x 24" faces are normally between 592-597 mm & 2" depths are normally between 45-48 mm. (Some filters may have the nominal size stamped on the filter, say 24 x 24 x 2" or 610 x 610 x 50 mm, the actual filter size will however be smaller).
