ISO Hood

The ISO Hood is a cost effective and un-complicated bench top enclosure which can be designed with either unidirectional (laminar flow) or non-unidirectional (turbulent) air flow intended for the creation of a small ISO certified enclosure.

The laminar flow booths are designed and built to suit the dimensions of the process it is to enclose but we do offer some sizes as a starting point.

1200mm or 1800mm wide x 600mm deep x 700mm internal height plus fan box
We have built taller and or deeper units to allow for pieces of equipment and L shaped and even T shaped arrangements to allow for full process enclosure. As we build to order we can accommodate almost all requirements.

The normal orientation is for the HEPA or ULPA filter to be positioned on the top providing vertical, unidirectional airflow however we can also mount the HEPA to the rear for horizontal, unidirectional airflow.

As with all ISO Cleanroom we keep a keen eye on the standards so that our clients don’t have to. The ISO Hood is a fully testable enclosure designed in accordance with Cleanrooms and associated controlled environments – Part 7: Separative devices (clean air hoods, gloveboxes, isolators, and mini-environments) (ISO 14644-7:2004) with reference to ISO 14644-4:2022 as an unrestricted air overspill unit with aerodynamic separation. As such there is no pressure differential between the interior and exterior of the unit.
The unit is designed to enable testing according to ISO 14644-1:2015, ISO 14644-2:2015 and ISO 14644-3:2019.

The ISO Hood is designed to operate within the classification limits of ISO 5 for a particle source strength of 50,000 particles per hour at 0.5 micron.

Applications include:

  • Protection of sensitive equipment
  • Protection of sensitive processes

I knew of Toni and her team from around 2003 and the days of their Clean Tent business. With a small new business that needed a clean room, I went straight back. Very helpful discussion with Toni led me to choosing a custom lamina flow hood (cheaper!) which was delivered bang on time, immediately passed an ISO 1385 audit and has been cheerfully maintained ever since. I'd go back to ISOClean because they know their stuff and do what they say.


ISO Cleanroom were very easy and practical to work with. Both Toni and Amaleed were knowledgeable and very flexible - looking forward to working with them in for future projects.

I recently contracted Iso Cleanroom to design and build two modular ISO Class 6 cleanrooms so that our small orthobiologics company could implement in-house manufacture. They delivered on all of their commitments on cost, schedule and quality with no fuss. They showed up they day they said the would and finished up the day they said they would. They were extremely organised and meticulous, and helped us to address some unforeseen issues that cropped up during the installation.

We contracted ISO Cleanroom to design, build and validate a large cleanroom in our new facility. Toni really knows her business, and was very helpful through the design process, enabling us to make the most of the available space. When it came to installation, Anthony and his team did an exceptional job, keeping the install to schedule. We are very happy with the professional service we have had from ISO Cleanroom and would not hesitate in recommending others to use them for any cleanroom requirements.
