UV222 Material Airlock

The UV222 Material Airlock offers a microbial decontamination solution for larger equipment, ensuring a rapid process that prepares the equipment for transfer between cleanroom zones without causing any material degradation or particle transfer.

Ensure equipment decontamination during transfers

The UV222 Material Airlock forms a protective barrier between cleanroom zones, ensuring seamless equipment decontamination during transfers and effectively preventing particle transfer, safeguarding the cleanliness standards of the cleanroom.

When transferring equipment to higher-grade cleanroom areas, decontamination is essential, encompassing both smaller and bigger items including substantial equipment such as vessels. Cleanroom requirements specify the number of particles and microbial load, creating a restrictive work environment, where every risk of contamination should be minimised.
