Dust collection unit e.g. for belt moved by motor driven pulley - has ventilation unit driven by same motor as that driving belt, and fan of ventilation unit coupled by shaft coupling to pulley driving belt

摘要

The ventilation unit(2) has a housing(8) with the fan(9) of the ventilation unit arranged therein. The housing(8) is connected to the fan, and encircles the driving pulley(4) fixed at the holding unit(6), in which the driving pulley(4) is located. The ventilation fan(9) is coupled by a coupling unit(14) with the pulley(4) driving the belt, and the housing(8) is fixed with the ventilating fan(9) at the holding unit(6), allowing removal. USE/ADVANTAGE - Esp. band grinding or sanding machines. Less expensive in engineering sense, it is cost effective, compact and easier to transport.
