<p>PURPOSE:To prevent settlement of dust on precision parts and at the same time, enable static elimination of precision parts by providing an ion generator for supply of ions into a clean air purified after passage through a collector in a downstream side of the collector. CONSTITUTION:Dust-containing air 11 coming in from the exterior of a device 7 is sucked into the device 7 from an inlet 8 by rotary drive of a fan 10. This sucked dust-containing air 11 is supplied to an ionizer 12 by the blowing pressure of the fan 10, and in the ionizer, dust particles in the dust-containing air 11 are charged by corona discharge. Next, this air is allowed to pass through a collector 13 to purify the dust-containing air 11. This purified air 22 is supplied to an ion generator 14 and the purified air 22 containing ions generated by the ion generator 14 is discharged to an assembly site from a discharge port 9. During assembly, a static electricity on precision parts is eliminated by means of ions, thus the attraction of dust to precision parts by static electricity is eliminated and the subsequent assembly of precision parts in a clean state is always achieved.</p> |
