Dayton HV2131000G Impeller Dimensions

Fitment and Compatibility Constraints

Questions about this item

Which impeller length matches my 77 in housing?

The 77 in overall length fits housings built for that exact dimension; the 39 in width must also clear the frame.

How does the 77 in length affect airflow in my RV blower?

The longer drum moves more air per revolution, so the blower delivers higher volume at the same motor speed.

What mounting standard does the 3AA26 reference guarantee?

The 3AA26 cross-reference confirms bolt pattern and shaft size match the original Grainger assembly.
