A DEVICE FOR REDUCING PARTICULATE AIR POLLUTION

摘要

The invention provides aspiration efficiency reducing device comprising a ventilation inlet for receiving airflow, an airflow diversion means, and a directional means, characterised in that the directional means is adapted such that the ventilation inlet is facing substantially opposite the direction of airflow. The device operates by manipulating the fluid physics and the forces of inertia and gravity on particles (i.e. factors which affect AE) to minimise the amount of particulate air pollutants entering through it, without any filters, motorised parts, energy input or consumable requirements, in a simple effective solution to reduce air pollution exposure in an enclosed area.
