Q: What does the Bayliss Autovent do?
A: It opens and closes a hinged vent automatically using energy from the warmth of the sun or the surrounding air. The hotter it gets, the wider the autovent opens the vent. And because it uses no electricity etc, it is a very environmentally friendly product.

Q: What maintenance should I do on the autovent?
A: The only maintenance needed on the autovent is a general wipe down from time to time, and a little oil applied to moving parts. It’s also a good idea to carefully wipe the piston rod a couple of times a year.

Bayliss Autovents and Autovent Spares can be purchased online, worldwide.
