#1 Q:   Can this be installed in conjunction with a Fantech SHR air exchanger? If so, it presumably gets attached to the house supply side after the exchanger?
A:   Yes it can. It should be installed between the outside air intake and the HRV. That way you keep the core from getting clogged with any outside air dust.

#2 Q:   What is the maximum CFM you can flow through the Fantech FB filter box?
A:   No hard number but Fantech stops publishing data past roughly 190 CFM. In fact, the listed pressure drop starts to go up drastically around 140 CFM...

#3 Q:   How often would filter replacement be required in an hrv application given reasonably dust free supply air?
A:   Per Fantech: Replace your filter every 3 months. Adjust your maintenance schedule based on how dirty the filter is when you replace it. If the inside of the cabinet is dirty, wipe with a clean, damp cloth.

#5 Q:   can this serve to vent dryer exhaust whith flexible dryer hosing leading to it from dryer?
A:   I recommend the Fantech DBLT4 Lint Trap for such an application. This would clog very quickly with lint.
