• COMPACT YET POWERFUL - This inline fan utilizes dual jet type blades to achieve high airflow of 160CFM. It moves A LOT of air for size and power, It's a lot bigger in terms of cfm movement! It is smaller, stronger and consumes less. Occasions when ducts were extended, backflow preventive damper or deodorizing filters were installed, suction power would not be significantly weakened. It can operate in 24/7 heavy-duty conditions.
