250mm acid firefighter KJ30/250

Firefighter - chimney cowl made of stainless steel 1.4404. Its main application is to support the gravity chimney by creating a negative pressure in a situation when the wind blows the root. It faces the direction of the wind, thus covering the chimney opening. The firefighter can be used for both ventilation and exhaust chimneys. In no case, however, should it be used for smoke pipes fired with solid fuels such as coal, fine coal or eco-pea coal. It is permissible to install on a chimney to which a fireplace is connected, and the fuel is wood. The fireman is available in diameters from 100 to 350 mm. It is produced in two versions - on a sleeve bearing and a ball bearing.
