What’s the maximum length of vent pipe you can have?

For the Separett Tiny, we recommend a maximum length of 4 metres with a couple of ninety-degree bends. It is possible to fit a second fan to the Tiny if you need a longer vent pipe run or more bends, but this will increase the noise levels.

For the Villa (models made after 2020), you can have up to six metres of vent pipe. For more information on possible Villa vent pipe configuration and the range of parts, see this page.
