WHITEPAPER - THE DOOR IS THE BREACH

Cleanroom contamination control is usually discussed in terms of filtration, air-change rates and pressure cascades. But there is a moment, repeated dozens of times a day, that none of these steady-state provisions account for: the swing of a hinged door.

Our new white paper synthesises recent CFD research showing that within one second of opening, a door can collapse the pressure differential between an airlock and a cleanroom almost entirely, allowing aerosols to travel deep into the protected zone. The paper explains how door speed and direction shape this contamination pathway, and highlights a simple, no-cost operating protocol, opening slowly and closing quickly, that cuts contaminant levels by 21 percent.

Read “The Door Is the Breach” to find out what this means for the design of your airlocks and doors, and for the operating procedures that govern them.
