Allowing fresh air into a waste tank reduces anaerobic growth and the build up of gas. However, unpleasant odours can also escape through this air breather line.
This can be prevented by the installation of a VETUS no-smell filter. The no-smell filter is easy to install and contains activated carbon material to absorb odours.
The no-smell filter element contains a special odour-absorbing material. The filter element is exchangeable and should be renewed once a year.
