As a result, the air pressure created within the room is greater than the ambient pressure, thereby reducing particulate intrusion around minor unsealed areas in ceilings and walls, as well as around doors. Along with the particles which it carries, Cleanroom air is exhausted outside and at the same time, laminar flow of the air coming in is promoted by installing wall venting near floor level.
Our negative pressure modular rooms are built to prevent contaminants from getting into the exterior environment, unlike positive pressure modular Cleanrooms which protect the internal environment. Our default design uses HEPA filters and air handlers or exhausting FFUs to get rid of the air inside. The processes carried out in the Cleanroom contaminate the air, which is then removed to a secure place. Either using filters or directly, external air is drawn into the Cleanroom due to the negative pressure created by the exhaust system.this text.
All our cleanrooms will be validated upon commissioning. A certification of air cleanliness will be provided in accordance with ISO 14644:2015.
Our Cleanrooms are ruggedly and beautifully constructed, so you only have to wipe down as you normally would to keep it clean for the most part. You can use mild bleach and IPA solutions to clean the room, including on the Softwall material that’s designed to be chemically resistant.
Once you clean as necessary, the only other maintenance protocol is changing light bulbs and FFU filters. The pre-filters will need to be changed regularly and the HEPA filters tested in accordance with ISO 14644:2015.
Both Hardwall and Softwall Cleanrooms can be designed to be on par in terms of the air change per hour. However, you’ll get a better barrier with Hardwall Cleanrooms. Furthermore, Hardwall Cleanrooms give you more control over humidity and atmospheric temperature. While Softwall Cleanrooms have the advantage of being mobile, they are not as easy to clean and airflow can be more turbulent, since the walls are not fixed. Also, Hardwall Cleanrooms are better at preventing particulate intrusion, as they can hold a significant positive pressure.
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.
It doesn’t take long for us to install your Softwall Cleanroom. Generally, you can expect it within three days of being released. Since our Softwall Cleanrooms are custom made, they take about four to Six weeks to manufacture. However, our Hardwall Cleanrooms take a little longer, usually six to eight weeks, depending on the workloads and complexity of the project. Please place your order well ahead to ensure it gets to you on time. If you have any further questions about our processes, please don’t hesitate to call us on 12345677.
Such controls require custom engineering as a result of how all softwall Cleanrooms work. If you want that done, we can handle it.
The provisions for the activities to be carried out within the Cleanroom will determine the classification needed. We can advise you based on our experience in the industry. The cleanliness level is based on an ISO standard and given a grade between 1 and 10 depending on the level of particles allowed to enter the cleanroom.
There are various ways a Cleanroom can remain clean. For instance, the technicians who work in the Cleanroom must wear special clothing that’s designed not to allow particles to escape. Usually, personnel will walk through an air shower before entering the Cleanroom in order to blow off any particles using high velocity air.
Within the Cleanroom itself, items such as mouldings and ledges are avoided as much as possible, as dust can easily settle on them. In addition, we create an air flow pattern called laminar flow, which continuously directs and recirculates the air through special filters in order to keep it clean.
Cleanrooms are used in industries where manufacturing processes may be affected by small particles. Such industries include military, fibre optics, critical process in manufacturing, medical, pharmaceutical, biotech and aerospace, amongst others.
A Cleanroom is a custom built room where the particles in the air are controlled and kept within specified limits. They are used in various industries, where it’s essential to keep airborne particulate contamination below a given level.
