Cleanroom Concepts – the How and Why

Why dust makes our lives difficult?

The dust that lies in large clumps in corners is easily visible and can be easily removed by dusting. But we want to deal with the dust that can no longer be perceived so well with the naked eye. To do this, we arbitrarily pick 2 events from the past year. One event is Saharan dust, because last yea…

The innovative quattroClean Powerjet technology enables dry, fully automated inline cleaning processes. Recycled, liquid carbon dioxide is compressed into granular cleaning material within an integrated system and directed at the surface to be cleaned, accelerated by compressed air. (Image source: acp systems)

The continuous, interruption-free media supply is the essential prerequisite for fully automated, production-integrated cleaning processes in which the nozzle is guided by a robot. (Image source: acp systems)

Differently designed nozzles enable the optimal adaptation of dry cleaning to various tasks. The nozzle design and dimensions also ensure that hard-to-reach component areas can be cleaned. (Image source: acp systems)
