How does a periscope dryer vent work?

A periscope dryer vent is a type of venting system that allows for the efficient expulsion of hot, moist air from a dryer while minimizing the space required for installation. It features a vertical and horizontal ducting system that can be adjusted to fit tight spaces, typically allowing for a vent run of up to 6 feet. Air is directed through the vent by the dryer’s fan, and the periscope design helps to keep the ducting as straight as possible, reducing the risk of lint buildup and improving airflow. This design is especially useful in apartments or homes where traditional venting is not feasible.
