Potential axial flow fan for low pressure drop solar space heating systems

This Dayton 10 inch diameter fan (or similar fans) might be a candidate for solar space heating systems that require relatively high flow rates, but have low pressure drops (low flow resistance).

The advantage is low power consumption for its relatively high airflow.   As the fan curve below shows, the pressure drop for the system has to be relatively low for this fan to produce good flow rates. 

This fan might also be a good candidate for transferring sunspace heat to the house.
