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 re-designed 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.
