Your clothes dryer is made to remove moisture from a load of wet clothes. It does this by heating air from the living space and blowing in through the load of clothes as they are tumbled to increase the surface area exposed to the heated air. Moisture evaporated from the load is then forced through the lint trap and out the dryer exhaust system which is vented outside the home. Anything thing that creates a restriction in the duct path lowers the vent port velocity and decreases the dryer’s ability to remove the moist air from the clothes drum.
Things that lower vent port velocity:
Clogged lint trap. (Clean the lint trap after every load.)
Kinked or crushed transition duct.
Excessively long duct path.
Excessive use of bends and turns.
Rough interior surface of ducting.
Lint accumulation in vent pipe, transition duct and dryer.
Vertical vent paths.
MagVent, a properly designed duct system, and routine cleaning are the solution to boost dryer efficiency and save energy!
