• Height and Width Code: The first numeral represents the number of 24” x 24” filters high or wide. If 24” x
12” filters are also used in the height or width, the second numeral is “5”.
• Service Location: U (upstream) or D (downstream).
• Lever Location: L (left side) or R (right side) when facing in the direction of airflow (air directed at your
back).•
For special features or sizes: Use Suffix “X” and describe them.
This example represents a K-Trac module, 2 filters high and 3-1/2 filters wide, upstream service and left side
levers. The letter X indicates that special features are required.
1. Height and Width Code: The first numeral represents the number of 24” x 24” filters high or wide. If 24” x 12” filters are also used in the
height or width, the second numeral is “5”.
2. Dimensions are based on using nominal size 24” x 24” and 24” x 12” filters. Select filters from capacity charts for Precision Pak bag filters
or single-headered PrecisionCell or Rigid-Air filters.
3. Sizes using 24” x 12” filters in both height and width require a 12” x 12” blankoff; for example, a KT- 15H35W has a 20 sq. ft. available,
not 21 sq. ft.
4. For capacities other than those shown, ratio the face velocities.
