The problem of unorganized emissions of natural ventilation dust has been around for a long time, and the environmental pollution and enterprise management problems brought by it have always been an intractable problem.

        The roof natural ventilation dust collector, according to the gravity dust removal and inertial dust removal mechanism, increases the corresponding dust removal process in the ventilation process of the natural ventilation device, reduces the dustless tissue emissions, and recycles the dust to reduce the production cost. The product also has protective measures to reduce the impact on the job entry when dust is collected.

Roof ventilator exhaust volume estimate（kg/h-m）

Note: In the table, hp is the height difference between the center of the exhaust vent and the neutral zone (m); Tp is the exhaust air temperature (℃); Tw is the outdoor temperature (℃); the drag coefficient ξ=1.42。
