Predesigned Hardwall Cleanrooms
Our predesigned hardwall cleanrooms make it easy to introduce or expand controlled environments without impeding on quality or compliance.
Built with a powder coated steel frame, PETg wall panels, and available in a range of popular sizes, these high-integrity modular cleanrooms are a scalable, future-proof solution for a wide variety of industries and operations.

What are predesigned hardwall cleanrooms?
Our predesigned hardwall range has been designed by you . . .
From years of collaborating with clients worldwide, we’ve created a ready-to-ship solution combining highly-requested sizes and popular specifications – ideal for a wide range of industries.
This means you skip the design phase, reduce lead times, and quickly get started with your production process.
Due to popular demand, hardwall cleanrooms now offer optional door positioning during the build – improving accessibility and orientation. Each hardwall cleanroom has been predesigned with HEPA filtration – creating an ISO 14644-1 compliant environment, perfect for universities, injection moulding, manufacturing, packaging, start-ups, and more.

Looking for something a little more bespoke?
Connect 2 Cleanrooms offer a complete cleanroom design and build service. Our bespoke modular cleanrooms create classified environments to protect processes from harmful airborne contamination – reducing failure rates and helping organisations get it right first time.
We manufacture a cleanroom of a few square meters, to hundreds of square meters, with the ability to install bespoke designs around existing machinery where needed. The modular design means that our cleanrooms can be extended or relocated, so you can grow your production area as demand increases.

Frequently asked questions
Yes! Due to the way the steel frame is designed, you have multiple options for door positioning without the need for any design modifications. We also offer additional custom features including transfer hatches and upgraded ISO classifications. However, these enhancements may result in this becoming a custom-built project, which could extend lead times.
Our predesigned hardwall cleanrooms can be delivered in just 2 weeks and installed within 48 hours of our engineers arriving onsite.
Predesigned hardwall cleanrooms should be validated in line with ISO standards – it’s recommended that cleanrooms are validated at least once every 12 months.
Our predesigned hardwall cleanrooms are made using robust steel framing with a hygienic coating, and PETg hardwall panels for exterior walls.
