Do not put your cleanroom at risk halstrup-walcher maintains the overpressure – to prevent contamination

Cleanrooms must be kept at a constantly higher pressure than their neighbouring areas in order to prevent infiltration of contaminated air from outside. This is not just required by the relevant standard ISO 14644-4. Every expert in this area knows hour air quality can quickly deteriorate if the overpressure falls by just a few Pascal even temporarily. In the area of semiconductors, dust particles and other pollutants threaten to compromise highly clean finished products. In the pharmaceutical sector, hazardous substances can penetrate highly critical medicines. Obviously, this must be prevented safely.
