Air contaminant integral collecting method

摘要

The method involves using a filter (6) under a housing (1) and a ventilator (3) via which air passes through. Contaminants in the air collected in the passive collector are separated in a filter (6). The quantity of air passed by the filter is held essentially constant by the ventilator which blows the air at the filter in a controlled manner. The ventilator can be mounted above, below or laterally w.r.t. the filter and can be driven by a battery or solar cell. Its dia. is greater than that of the filter and it is mounted in a tubular housing protruding slightly beyond its rotor surface, with one end forming a filter holder (5).
