Fiberglas Dust-Stop "L** and "V" duct or plenum chamber but requires Filter Frame Assemblies are specified by engineers of commercial and industrial heating, ventilating and air conditioning. Frame members of heavy steel are as a larger face area for the same CFM capacity. The "V" type frame requires a face area approximately the same as the cross-sectional area of a duct which will sembled in combinations to satisfy any handle the volume of air for which the CFM and space requirement. filters are rated. Both types of frames are designed for the convenient and correct handling of Dust-Stop filters. They meet all Fire Underwriters' and local Fire Ordinance requirements. The choice between the "L" type and "V" type frames is determined wholly by the space available for the filter frames. The "L'\ type filter frame takes less depth within the Two Depths of "L" Frames--The "L" frame, two filters deep, is designed to hold two Dust-Stop No. 1 filters in each cell. The "L" frame, four filters deep, holds four Dust-Stop No. 1 filters in each cell. The frame that is four filters deep is identical in every way to the frame two filters deep except that the depth of all parts is 2 in, more. When specifying "L" type frames indicate two-filter or fourfilter depth. "V" frame is available, four 1-inch filters deep per cell, only. The "L" frame uses 20 x 20 in. filters only. The "V" frame uses 20 x 25 in. filters only. Filters are always used two or more in series in each cell.
