SECTION III: FILTERS
FILTER INSTALLATION
All applications require the use of a field installed filter. All filters and mounting provision must be field supplied.
Filters must be installed external to the furnace cabinet. DO NOT attempt to install filters inside the furnace.
NOTE: Single side return above 1800 CFM is approved as long as the filter velocity does not exceed filter manufacturer’s recommendation and a transition is used to allow use on a 20x25 filter.
Table 4: Recommended Filter Sizes (High Velocity 600 FPM)
CFM | Cabinet | Side | Bottom |
(m³/min) | Size | (in) | (in) |
800 (22.7) | A | 16 x 25 | 14 x 25 |
1000 (28.3) | A | 16 x 25 | 14 x 25 |
1200 (34.0) | A | 16 x 25 | 14 x 25 |
1200 (34.0) | B | 16 x 25 | 16 x 25 |
1600 (45.3) | B | 16 x 25 | 16 x 25 |
1600 (45.3) | C | 16 x 25 | 20 x 25 |
2000 (56.6) | C | (2) 16 x 25 | 20 x 25 |
2200 (62.3) | C | (2) 16 x 25 | 20 x 25 |
2000 (56.6) | D | (2) 16 x 25 | 22 x 25 |
NOTES:
1.Air velocity through throwaway type filters may not exceed 300 feet per minute (91.4 m/min). All velocities over this require the use of high velocity filters.
2.Do not exceed 1800 CFM using a single side return and a 16x25 filter. For CFM greater than 1800, you may use two side returns or one side and the bottom or one side return with a transition to allow use of a 20x25 filter.
