<p><P>PROBLEM TO BE SOLVED: To provide a high-speed tunnel fan with an electrostatic filter which can clean the air inside a tunnel by collecting soot, smoke, contaminant particle and microdust in a tunnel, and can achieve a high dust collection efficiency even at a higher air flow rate than 10 m/s (e.g. about 15 m/s to 30 m/s). <P>SOLUTION: This tunnel fan is equipped with an electrostatic filter, including a cylindrical tunnel fan and a pipe assembly, and this pipe assembly incorporates a plurality of pipes arranged in parallel in order to form a cylindrical shape. In addition, each pipe has an electrostatic induction means for collecting microdust by means of inductive voltage, and the electrostatic filter is connected behind or ahead of the tunnel fan. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
