Greenheck Fan manual Filter Options, Model SQ, Model BSQ, Model Selection Procedure

Filter Options

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 for the preliminary model size selected in step 2 using the equation:

P = Fx ( 10,000cfm )2

4.Add the filter pressure drop (P) to the system pressure drop and make a revised model size selection. Use the charts on the left to determine filter factor (F).
