The DUNDAS-JAFINE ProMax™ dryer vent kit is part of the ProSeries product line-up. The kit includes a 4 in ProMax™ exhaust hood, a 4 in x 8 ft ProFlex™ 2158A listed and marked transition duct and 2 plastic adjustable clamps. The ProMax™ exhaust hood features a robust, wide mouth cap for optimum airflow and snug fit backdraft damper that prevents cold air, snow or rain from entering the home. The damper has been redesigned for great noise reduction. Additional features of the hood include a removable pest screen that helps to keep pests out and allows for easy cleaning of the duct as well as a snap on pipe to cap assembly that eliminates the need for lint trapping staples. All ProMax™ products have a UV-resistant coating to prevent the cap from discoloring and are paintable to match the exterior of your home. These hoods can be used in conjunction with brick, concrete or siding.
