Inertial dust collector: To improve the effect of dust gravity settling chamber may be provided in various forms baffle in which airflow direction made an abrupt change of ventilation ducts, use dust inertia or collide it and bezel and trapping . Suitable particle size 20 ~ 50μm. Measures to achieve uniform air: 1, set a different resistor element in the opening, so that different orifice has a different resistance (ie changing the flow coefficient). 2, when the value of the same opening area and μ ventilation duct, the duct may be tapered to change the sectional area of ??the draft tube tin ventilation pipes, the inner tube static pressure remained unchanged. 3, air hose cross-sectional area and opening μ value unchanged, may vary according to the static pressure within the tube, changing the aperture area. 4, increasing the air hose off the area, reducing the opening area.
