Product overview

About this product

This Yield Lab blower uses a 4-inch flange and carries a merchant-stated free-air rating of 190 CFM. It can serve as the active exhaust in a small grow-space plan, but the useful airflow will be lower once duct length, bends, intake restrictions, and a carbon filter are added.
