Today, facility designers generally prefer internal lint screens (a Milnor option) or close-coupled ® lint collection systems installed on each dryer. However, if the facility uses a common, powered lint collection system, you can connect the air exhaust from two or more dryers to this system if you run separate ducts from each dryer.
