A commercial dryer vent fan supplies more power and more airflow, thus permitting proper venting of a laundromat or large building. A residential dryer vent fan is small and cheap, and it’s easy to install and maintain.Ĭommercial dryer vent fans have to deal with larger, multi-story buildings or multiple dryer units, which may themselves output more lint and exhaust than your typical residential dryer. Thus, a residential dryer vent fan only needs to supply a small amount of extra airflow to cope with a long exhaust vent. A residential dryer fan generally doesn’t need to vent more than one or two dryers, those dryers aren’t usually very large, and vent runs are usually much shorter. The unit weighs 25.5 pounds.Īs we can see from the two products, the major technical differences are airflow and capacity. It can accommodate up to four laundromat-capacity dryers with a combined airflow of 1,000 CFM. It fits into a section of 8” duct, either as a 90-degree elbow or in-line with an added kit from the manufacturer. The Tjernlund CDB8 is a commercial dryer booster fan. The specific model of dryer booster fan you’re getting will also determine how much extra distance of vent run it can handle, so before you get one, make sure to measure just how long your vent run is, and compare that to your chosen dryer booster fan’s manual to see if it can handle the length of your vent. It’s also equipped with a sensor that turns it on when the dryer is running, saving you the trouble of having to manually turn it on before you start your dryer cycle. The booster fan is mounted onto the duct, sometimes in-line, sometimes offset. Lint buildup within your dryer vent will create a blockage that reduces airflow, leading to reduced performance, longer drying times, greater usage of electricity, and a potential fire hazard.Ī dryer booster fan solves this problem by increasing the airflow in the duct, thus carrying away lint through the entire length of the duct. This means lint won’t exit the vent but instead build up inside. An exhaust run that’s too long or with too many bends will reduce airflow, especially as it gets further away from the dryer. The problem comes if you have an exhaust vent longer than 25 meters, or one with a lot of bends in its path. ![]() ![]() ![]() Your typical residential dryer outputs 160 CFM of airflow, so in most cases, there’s enough force coming from the dryer itself for lint and exhaust to clear the entire run. Generally speaking, an airflow of 100 cubic feet per minute (CFM) is needed to kick lint and exhaust out of a typical dryer vent. All the hot air and lint from a dryer’s operation has to go somewhere, which is why most dryer models need a vent duct to carry them away.
