Abstract: Disclosed is a dust collector that is essentially modular in structure, thereby making it easy to transport, position and assemble by the user himself or herself. This dust collector includes one or more filter modules, a fan module operatively connectable to one end of the filter module(s), an end plate for closing the opposite end of the filter module(s), and optionally a silencer module intercalatable between the fan module and the filter module(s) to reduce the noise of the fan. In use, the dust collector can be easily upgraded whenever required by merely changing the motor, fan wheel and inlet of the fan module and/or adding one or more filter module in order to increase the filtering surface area.
