Basic Dryer Air Flow

The basic airflow direction for all dryers is the same. Air enters the back of the dryer near the motor and passes through the motor to keep the motor cool. This is why you should never operate a dryer without a vent!

If a dryer does not have a vent, the humid, dusty air exits the dryer and immediately reenters via the air inlet. Lint builds up on the motor creating a fire hazard and premature motor failure.

Under normal conditions cool air passes through the motor and is forced by the blower past the heater into the drum. The now hot air passes through the clothes and enters the filter. It then leaves the dryer via the air duct that exits out the back of the dryer where you connect the vent
