This may be a stupid question... but...
I know code limits dryer vents to 35 feet, IRC M1502.4.6.1 (https://codes.iccsafe.org/content/IRC2021P2/chapter-15-exhaust-systems#IRC2021P2_Pt05_Ch15_SecM1502). However, there is another section (M1502.4.4) that says Dryer Exhaust Duct Power Ventilators can be installed according to the manufacturer's instructions. M1502.4.5 prohibits booster fans.
I'm probably confused, but does a dryer exhaust duct power ventilator do the same as a booster fan? Does a dryer exhaust duct power ventilator allow for the extension of a vent?
As I write this, I have to wonder if the power ventilator allows you to maintain the calculated distance of 35 feet if there are multiple bends that would otherwise be subtracted from the actual physical distance.
In essence, the measured physical distance must be 35 feet, but the calculated distance due to bends would be greater than 35 without a power duct ventilator.
I'm really trying to understand IF there is a way to extend a dryer vent beyond 35 feet or if 35 feet is the absolute maximum (unless manufacturer states it can be longer).
