Fume hood, injection exhaust fan, Kharkiv region.

The hood is designed to create and maintain the necessary draft in domestic solid fuel boilers, fireplaces, etc. It is made of special heat-resistant materials (engine impeller – special stainless steel). When ordering, the diameter of the chimney hood is selected specifically for the diameter of the existing chimney pipe so as not to use it.
With poor draft in the chimney, a household smoke extractor will help to avoid such problems:
- decrease in efficiency of heating equipment;
- accumulation of smoke in the room;
- resin accumulation in a boiler or fireplace;
- combustion in the furnace is inefficient, etc.
The DY smoke extractor is delivered assembled, completely ready for installation on theboiler. The design of the chimney does not narrow the chimney and does not prevent the passage of flue gases during natural draft in the chimney. On the flange of the engine there is a mounting cover, intended for installation in the hood of the vacuum cleaner. A special impeller is installed on the engine axis.
The smoke extractor can be installed both on vertical and horizontal sections of the chimney along the flow of flue gases. The connection points of the smoke extractor are sealed with heat-resistant sealant (up to 600 degrees), 162
