Flowing-in dust due to decreased pressure at factory

The factors that deteriorate the precision and quality levels of molding include dust in air. The count of suspended dust particles of 0.5 um or larger exceeds 1,000,000 per ft3 near Kowloon Bay, Hong Kong, where our company is located. When the factory is ventilated by a typical air-conditioning method using ventilation fans, the pressure at the factor will be reduced.
As a result, outdoor air will flow into the factory through the exit, entrance, and clearance of the building, causing the factory to be filled with more than 100,000 dust particles. The ventilation using ventilation fan is not ideal.
