Fireman with external bearing fi 300mm heat resistant KJZŁ1,0/300

Chimney cowl, acid-resistant fireman, gr. 1.0 mm made of 1.4404 steel. The main application is to support the gravity chimney draft by creating a negative pressure at the outlet at the moment when the wind blows the root and preventing backdraft. It always faces the direction of the wind, thus covering the chimney opening. The firefighter can be used for both ventilation and combustion chimneys. A fireman with a bearing is available in diameters from 150 mm to 300 mm. It is also possible to produce other diameters upon the customer's special request.
