The wall vent is connected to one end of the dryer exhaust duct and allows the hot, humid air generated by the clothes dryer to escape to the outside of the home. The wall vent also functions as the barrier between the exterior wall and interior of the home to keep pests and the elements outside. The DryerWallVent is a stylish, rugged wall vent, efficient at maximizing the airflow and improving the dryer's performance. It exceeds code requirements for safe venting of a dryer. Additional protection against bird and critter intrusion is offered by the Defender Access+ Vent Guard and the Insert Guard.
