<p>PURPOSE: To improve powder and dust capturing efficiency by installing an air cleaning apparatus having an air flowing route directly attached to an open part formed in a box body to be attached to a running body while the open part being set to face to the proceeding direction of the running body. CONSTITUTION: A box body 1 is composed of a closed-type casing and an open part 2 for air suction is formed in the front side. The open part 2 is so set as to face to the proceeding direction of a running body. An air flowing route 3 is continuously connected with the open part 2. The air flowing route 3 is so composed as to be partitioned like, for example, ducts, etc., and the flow of air sucked in the air route 3 is so adjusted by an air regulator 4 as to surely capture 85wt.% or more powder and dust even at as low air flow rate as, for example, 1.5m/sec. A metal net M to prevent dust, e.g. fallen leaves, etc., from entering is installed in the open part 2. Consequently, the quantity of the air flowing in the air flowing route 3 can be kept constant and power and dust capturing efficiency is improved.</p> |
