We installed a custom designed and purpose-built cleanroom for our Qbig valves and filters for the high-end packaging industry. The cleanroom consists of a main working space, a goods receivable and a goods deliverable area. Having our own cleanroom is completely in line with our company vision, quality and traceability first.

In April 2022 we had our cleanroom and procedures audited for GFSI Standard BRC Packaging ISSUE 6. Our cleanroom is fitted with two fan units provided with ULPA U15 (99,9995% @ 0,12 micron) filters, that ensure a particle measurement to the specifications of an ISO 14644-1 Class 7 cleanroom. These filters provide 16 air changes every hour. On regular basis, we have air quality and migration tests performed throughout the cleanroom to ensure our procedures are effective and meet the official ISO 14644-1 Class 7 standards and requirements.

As you can see in the results below, the particle measurements have stayed below the maximum quantity allowance, needed for the -Class 7 certification.

≥ 0.3 mm ≥ 0.5 mm ≥ 1.0 mm
Iso 6 – maximum quantity allowed 102.000 35.200 293
