Does anyone have any experience with the GE LM2X AAF intake filter house with respect to any pre-filters prior to the inlet chiller coils?

It appears in the AAF drawings that the only thing upstream of the coils is the trash screens?

In areas with trees we would expect that there would be heavy fouling, especially in spring and fall, of the coils without some media to pre-filter the intake combustion air.

The installation will be for a new GE LM2500+G4 DLE gas turbine package with the filter house install on the roof of an existing building. Lots of trees surrounding the building the can not be removed (touched).
