Additional Information

Bayliss Autovents have the lowest failure rates in the industry and are manufactured to last. Each autovent is guaranteed for two years against faulty manufacture. Provided the unit has not been tampered with (i.e. the piston pulled out of the tube), damaged by the window being tied shut, damaged by unusually strong high winds or fitted incorrectly, then we will repair it free of charge if it is returned to us.

Our Autovents are not ‘throw away’ items and are designed and tested to last many years. However, each and every part of a Bayliss Autovent can be serviced should the need arise, and we carry spares for all our current units as well as many earlier models.
