Concentric Ducting Reducers
It's sometimes necessary to use a reducer. For example you may have a large powerful fan but only wish to make a small hole in the wall of your building for air to travel in and out. A reducer will help you do this. Below we list the most commonly used reducers. If you require one not listed then please call, we may be able to source it for you. All reducers are constructed from galvanised steel.
