Actually, i think it would be the contrary, the fan will blow the same quantity of air, so it will likely increase the cfm by around 30% to 50%. I think that since there will be an opening in my system (exhaust), there will not be the creation of a significant added resistance. I.e., 1 inch tubing doesn't create a bottleneck which would reduce airflow, but would instead accelerate airflow. I think this would increase airflow between 28 to 35. 1 1/2 is the exterior of the heat gun nozzle, so there is actually a smaller diameter of air flowing through.
