Abstract

As shown in the reference diagram showing the installation state, this product is a ventilation fan that is installed in a through-hole formed in the floorboard of a building and exhausts air from the indoor space into the space under the floor. A base plate is placed on the periphery of the through-hole in the floorboard, and a dust collector is supported on the base plate. The suction port of the dust collector facing the indoor space is covered with a cover, and the cover has multiple through-holes through which air and dust from the indoor space pass.
