Ventilation and aspiration of public, industrial, private facilities, production shops, cottages, houses, apartments, and also conditioning and heating.

Not only availability of fresh air and its temperature, but also speed of the movement of air streams is important for comfortable stay of the person in the house. And the it is less, the more comfortably to be in the room. Air exchange indoors with a mechanical supply and exhaust ventilation (the fan on inflow and on an extract) is more, than indoors with natural ventilation. It is connected with the normalized volume speed of the movement of air, various for them, in ventilating system. For mechanical ventilation it makes 3-5 m3/hour, and for natural no more than 1 m3/hour, that is is 3-5 times less. Therefore indoors with natural ventilation (both inflow and an extract) to be more comfortably.

Aspiration (the removing dust ventilation) is intended for removal of dusty air from under shelters of transport processing equipment and a working zone. For elimination of pylevydeleniye systems of aspiration with an extensive network of air ducts and the gas-purifying equipment are used. Design includes collecting basic data, calculation of aspiration networks, a portrayal of plans and cuts. Calculation of aspiration installation with selection of the equipment, necessary on productivity (fans, pyleotdelitel), drawing up the plane scheme with the specification of air ducts and ecological characteristics is made. At design, installation and adjustment all standard requirements have to be observed.
