Custom-fit modular cleanrooms, designed and built for your business.
Rigidwall Cleanroom

Rigidwall Cleanroom

Flow’s rigidwall cleanrooms bring a higher level of sophistication to your high-performance environment.

The carefully designed panelized wall structure of this cleanroom differentiates it from Flow’s softwall and hardwall solutions. It’s more solid and robust than the curtain-like perimeters of the softwall solution, yet less dense and easier to relocate and reconfigure than the traditional panel solution.

If security matters, and your business requires full control over air pressure, increased control over temperature and humidity, and the ability to make recirculating air flow, Flow’s rigidwall cleanroom is your optimal solution.


More sophistication. Lean cost. Increased control.
