blower apply to the system of ventilator and blower for vapor boiler
below 2～670T/H in the power plant.While having no special requirement,G4-73-11
may also be used for mine ventilation and ordinary ventilation.
The medium conveyed by the ventilator is air,no more than 80℃ of
the highest temperature.The medium conveyed by the blower is smoke,no
more than 250℃ of the highest temperature.

reduce as much as possible the dust in the smoke entered the blower.The
dust catching efficiency is no less than 85%.
Performance indicated in the performance chart,the performance
of ventilator is calculated according to the air medium that:ventilator
t=20℃,atmospheric pressure pa=101325pa,air density ρ=1.2kg/m3.The
performance of blower is calculated according to the air medium
that:air temperature t=200℃,atmospheric pressure Pa=101325Pa,air
density ρ=0.745kg/m3.
