Aspirotor Spinning Cowl
The Aspirotor is a great solution for problems with downdraught. Using the wind against itself, the stainless-steel turbine shaped head catches the wind causing it to rotate creating increased draw up the flue.
The Aspirotor can be used with every fuel type and adapter plates can be provided by Brewer Cowls for flue liners or awkwardly shaped pots.
Requires approximately 4mph winds to start rotation.
