The DH3500 building dryer is slightly larger than the DH2500.  The DH2500 building dryer is used where pressure neutrality is not an issue & capacity need is less. The DH3500 can dry a room pressure neutral.

Neutrality may be important.  If wet air is ducted outside a building, then air from outside the building must come in to replace it.  15% of air is exhausted during operation with the DH2500.

The DH3500 building dryer can also be used like the DH2500 building dryer just with one duct venting wet air out.
