The filter box is designed to provide a compact and convenient clean
air solution. Factory-assembled as a single unit, this fan eliminates
the costly process of designing, fabricating and installing special
remote filter box assemblies. Both the fan and filter section feature
removable access panels on both sides to remove and replace
filters, making fan maintenance simple and fast.

Model Selection Procedure
1. Calculate system pressure drop and cfm requirements
(not including filters).
2. Make a preliminary model size selection.
3. Calculate a filter pressure drop (P) for the preliminary
model size selected in step 2 using the equation: P = F x (
10,000
)

•
To determine the filter factor (F) refer to chart below.
4. Add the filter pressure drop (P) to the system pressure drop and make a revised model size selection.
