Yes, the Hillco fan kits are available and they do improve the paddle fan's airflow. The kit is a very good value at $100.00 and is worth putting in. Thank you for the comments on the rotor bars.
Marvin, how do you feel about this $100 dollar Hillco fan kit on a centrifugal fan with an air jet chafferIJ If there's any improvement at all $100 is pretty cheap.
