Title:
VENTILATION REGISTER
Document Type and Number:
WIPO Patent Application WO/2017/141962
Kind Code:
A1
Abstract:
Provided is a ventilation register that can suppress an increase in pressure loss while having the ability to trap, with high probability, extremely fine particles of contaminant substances. Provided is a ventilation register that is used at a natural air inlet, said ventilation register comprising an insertion tube that is attached by insertion into a vent of a building, a filter material through which a gas that has passed through the insertion tube passes, and a pre-filter between the insertion tube and the filter material, wherein the filter is a nanofilter. This ventilation register can ventilate efficiently by suppressing the entry of foreign material indoors while suppressing an increase in pressure loss.
