What’s the difference between a Softwall Cleanroom and Hardwall Cleanroom?

Not usually ideal for long spans and complex multi-room designs, Softwall Cleanrooms utilise flexible PVC curtains supported with a simple frame structure, made of steel. The curtains are lifted a few inches above the ground to allow for a vent through which the air can filter and may alternatively be made of non-outgassing Polysym. This type of Cleanroom is usually only used in cases where cleanliness ratings are lower, providing only the lowest of positive pressures. Such a Cleanroom would normally not have control over humidity and temperature, since there isn’t as much control over air flows. In smaller Softwall Cleanrooms, casters can be fitted so the area can be mobile.

Hardwall Cleanrooms make for a wall structure that’s more solid and an entirely confined Cleanroom with air vents. We can achieve varying levels of cleanliness in different parts of the room, as this type of Cleanroom holds higher pressure differentials. Types of designs that would need Hardwall Cleanrooms include humidity and A/C control Cleanrooms, positive/negative and negative pressure Cleanroom designs.

We utilise a variety of materials to make walls for Hardwall Cleanrooms, including polypropylene, polycarbonate, static-dissipative PVC and acrylic, using steel frames coated in powder. We also offer BioSafe hardwall Cleanrooms made from 316 or 304 stainless steel.
