Smoke exhausters of unilateral absorption of DN (D)

Centrifugal  smoke exhausters D and DN of unilateral absorption are intended for suction of combustion gases from fire chambers of the boiler units equipped with effectively operating systems of a zoloulavlivaniye and also for suction of combustion gases from fire chambers of oil-gas boiler units. Smoke exhausters are calculated on a long operating mode indoors and in the open air in the conditions of a temperate climate (a climatic modification At, categories of placement 1, 2, 3, 4, GOST 15150-69). Start of the device is allowed at a temperature in a snail not below -30 °C. The maximum temperature of combustion gases on an entrance to fans should not exceed +200 °C.
