Dryer Duct System Recommendations

Whether you’re experiencing problems with your current dryer duct or want to build a system that prevents future issues, this is what’s needed for the most effective and complete dryer duct system possible.  The two most important components are the Dryer Booster Fan and Lint box.

Booster fan
In all concrete high-rise buildings, a booster fan is a must. Even some townhouses, low-rise buildings, and houses will benefit from having one. Clothes dryers are not powerful enough to work effectively with long ducts. This is where a booster fan is important—it adds the airflow power that the dryer lacks on its own.

Automatic timer for the booster fan
The dryer booster fan should turn on automatically and remain on after the dryer shuts off. Ideally, it should stay on for 10–15 minutes afterward.

Secondary lint box
A secondary lint box is an important addition, especially when paired with a booster fan. Its purpose is to prevent lint from clogging the duct and to keep the booster fan clean.

Duct cleaning
Before installing a lint box and booster fan, it’s always best to start with a clean, clear duct. To do this, a thorough dryer duct cleaning is essential. I recommend Michael A. Smith Duct Cleaning (“MAS Duct”).

Installation considerations
The installation of the booster fan and lint box is crucial. They should be set up in a way that makes duct cleaning as simple as possible for technicians. Using flexible ducting with removable clamps makes the technicians’ job easier. A team of two technicians will often complete 25+ dryer duct cleanings per day in a building, so making the system easy to clean ensures a good result.  For the best installation information, visit dryerboosterfan.ca

Exterior venting
Another key aspect of a complete system is the exterior vent. A small, narrow-mesh screen will quickly clog with lint. It’s better to use a flapper vent or a 1″ screen.
