Dundas Jafine ProMax™ exhaust caps feature a robust, wide mouth cap for optimum airflow and snug fit backdraft damper that helps to prevent cold air, snow or rain from entering the home. The damper has been redesigned for superior noise reduction.  Additional features include a removable pest screen that helps to keep pests out and allows for easy cleaning of the duct.

NEW!
Dundas Jafine is pleased to introduce two new sizes of Pro Max exhaust caps. We have created larger 6 in. and 8 in. versions, ensuring you have the right size cap to finish the job!

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 caps can be used in conjunction with brick, concrete or siding and are ideal for bathroom fan venting, dryer venting and kitchen range hood venting . The molded caulk edge on the cap helps to maintain a clean caulking application.
