Softwall Cleanrooms - CZT III

Free Hanging Modular Softwall Cleanroom

The CZT III modular softwall cleanroom is our most economical room design. The CZT III is designed to meet requirements of a wide range of industries including the parts cleaning, electronic, clean packaging to name a few. It is our experience that the CZT III will be moved from one product line to another as required. The softwall cleanroom is totally freestanding or it can be used in combination with your existing walls and ceiling. The room comes in varying heights to 16’+ and can be equipped with an internal or external Gowning Room. The modularity of the cleanroom is also enhanced with the addition of locking casters.

The self-supporting ceiling system will accommodate either Fan Powered HEPA or ULPA filters. Fan powered filters are available with duct collar adapters for direct connection to your building HVAC system.

The air passes from your existing environment, through prefilters and final filter then exits the cleanroom under the free hanging curtains.

The versatile CZT softwall cleanroom has been a mainstay in industry for decades. It can be used for many applications and depending on size can be installed in hours. The CZT III softwall cleanroom is ideal for start-up companies that require a clean environment for process needs and to show prospective customers that they can meet their contract specifications. In some instances we have been able to eliminate the support structure and support the curtains from existing or added tee grid. This works particularly well where there are many restrictions, floor or ceiling. We have successfully divided areas with curtains as tall as 30’.

We have also installed the CZT III softwall cleanroom in one of our defense missile site locations where any static charge was a major issue. The unit was installed with grounding straps, static dissipative curtains, explosion proof light fixtures and HEPA filter units. A typical use is to install the CZT III in a factory or controlled environment where a cleaner area is required. Smaller units can be designed as “plug and play”, powered with a long extension cord. No problem if you need a light table inspection area, we can add black curtains, light-free doors and black tee grid and ceiling tiles.

The air passes from your existing environment, through prefilters and final filter then exits the cleanroom under the free hanging curtains.
