I am an electrical product approvals inspector and according to the manufacturers instructions, this product would not be suitable for use as a dryer booster fan. The instructions included with this product say not to install if temperature exceeds 122 degrees F. Typical dryer exhaust is between 120 to 160 degrees F. They go on to say not to install where there is significant dust or humidity. Both lint (which is highly flammable) and moist air are present in dryer exhaust. Tjernlund does make a booster fan suitable for a dryer booster but this is not it. Installing this as a dryer booster fan could create a fire hazard.
