A dust collector for a bank-note counting machine is provided to maintain the agreeable indoor environment by utilizing the air based on an internal circulation method. A dust collector has a base housing(100) having a built-in filter(400), and an air discharging tower(600) and air inhaling tower(620) which are installed at both sides of an upper surface of the base housing. By forming an air curtain, based on the air circulation method through the air discharge tower and air inhale tower with only one ventilator(200) which is built in the base housing, in front of a bank-note counting machine, the dust collector performs the dust collecting as preventing the pollutant and smell from being scattered.
