Air Cleaning Unit and Storage System Using the Same

摘要

The present invention provides an air cleaning unit which contains a blower, an acid/alkaline filter device, and a particle filter device. The blower draws in outside air through the acid/alkaline filter device and produces an air flow through the particle filter device. The acid/alkaline filter device absorbs the acid/alkaline gases in the outside air. The particle filter device traps the particles in the air flow. Through this design, the blower draws in air filtered by the acid/alkaline filter device. The blower therefore does not suffer erosion and therefore the air cleaning unit enjoys prolonged operation life span.
