Ionisation to Improve Cleanroom Air Showers
Air lock chambers to cleanrooms can have air jets for removal of contaminants. These chambers are known as air showers. The air used inside the air shower is fan-driven, usually self-contained, filtered and recycled. The air jets pass through nozzles known as punkah louvre nozzles which are directionally adjustable to suit the user’s needs.
Even cleanroom clothing can retain contaminant particles despite exposure to the jets of air. This is usually caused by electrostatic attraction to the garments, rendering the airstreams partially ineffective.
Ionisation to Improve Cleanroom Air Showers - Select a problem:
Ionisation of the airflow through the punkah louvres will allow neutralisation of the air jets and increase the cleaning efficiency of the air shower. Short range static eliminators such as the 3014 or 1250-S placed in the air plenum and directed at the inner face of the punkah louvres will provide an efficient solution.
