Recall of UniAir outlet valves 125R and 125Q

Outlet valve UniAir 125 - precautionary replacement of the rubber seal

Here you can assert your guarantee claims.

Background

Dear WOLF customers,

 

during continuous quality monitoring measures of our serial production, we detected that the used seal of the HAELIX exhaust valves  may be subject to premature aging. Under certain circumstances the originally used rubber compound can early become brittle, thereby influencing the mechanical properties of the component. As a result, the valves may become loose and can fall from the ceiling mounting. Affected are the part numbers 2577879 and 2577880 from the production period 01/2019 till 07/2021.

 

For reasons of preventive consumer protection and to eliminate the risk described above, we strongly advice for valves already installed to replace this seal with the improved version made from different rubber compound,  where embrittlement cannot happen anymore. The replacement is easy to carry out and can be carried out by you or by an installer.

We have prepared a contact form for you below, which you can use to register to request replacement seals. You will also find step-by-step instructions and an example video for replacing the rubber seal on this page.

 

We regret any inconveniences caused and thank you in advance for your understanding and cooperation!
