Dryer Vent Turn

[system]

Dear Internachi,

The article http://www.nachi.org/dryer-vent-safety.htm statesL

“vent hardware is available which is designed to turn 90° in a limited space without restricting the flow of exhaust air.”

What type of hardware does not restrcit airflow? Is the article referring to a regular elbow, or something else?

Thanks,
Kenneth

IMO… you’re reading it out of context. They’re not talking the technical engineering, but the functional traits… NO kinking i.e. restrictions…

2. It should not be restricted. Dryer vents are often made from flexible plastic or metal duct, which may be easily kinked or crushed where they exit the dryer and enter the wall or floor. This is often a problem since dryers tend to be tucked away into small areas with little room to work. Vent elbows are available which is designed to turn 90° in a limited space without restricting the flow of exhaust air. Restrictions should be noted in the inspector’s report. Airflow restrictions are a potential fire hazard.

For one example… think “In-Wall DuraVent Periscope”…
