  • Page 50 A system of this type could include pressure-sensing devices, a variable-speed booster fan, and a controller. 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.
