Q: How fast does the conveyor need to move through the air shower?
A: Optimal speed is around 10-20 feet per minute for proper exposure to the directed air jets.
Q: Can ultrasonics be used instead of air nozzles?
A: Ultrasonics can supplement air nozzles but are less effective as the primary purification method.
Q: How often should filters be changed?
A: Most manufacturers recommend changing HEPA/ULPA filters every 6 months under constant use. Pre-filters can be changed more frequently if they become overloaded with particulates.
Q: Can goods air showers fully sterilize surfaces?
A: No, they only remove dry contaminants. For true sterilization other methods like chemical sprays or vapor hydrogen peroxide systems should be used.
Q: Are goods air showers worth the investment?
A: In aseptic industries, the benefits of reduced rejects and higher quality generally provide a quick ROI making them very worthwhile.
