An Overview about Clean Rooms and its Types: A Guide for 2022


A room that contains HEPA filtration to get rid of particles from the air including dust, static electricity, or different types of microparticles and microorganisms, is known as clean room. Such rooms are used where high levels of cleanliness and sterility are necessary e.g. manufacturing of medical devices, pharmaceutical, semiconductor and many other applications including electronic, aerospace, food, USP797 compounding pharmacy or biotech etc.

Any industry that involves controlling contamination in their facility can use cleanrooms and hence in the government sector, these rooms are used in national labs, defense industries, and R&D labs at universities.

Cleanroom facilities include a range of preventative materials, devices and equipments to maintain a very clean, germ-free and bacteria-free environment. Some of these equipments are required for general staff protection, while others for maintaining clean air in the workplace.

So, how do cleanrooms work?

Cleanrooms use HEPA (high efficiency particulate air) or ULPA (ultra-low penetration air) filtration to eliminate particles from the air and generate an ultra clean environment. An adequate air changes per hour and laminar air flow is applied to decrease particulate count from around 500k/ft3 (in typical office space) to as low as 100k/ft3 (class 100 cleanroom).

To avoid contamination from entering the cleanroom, airlocks are used. Besides, workers usually have to wear cleanroom garments like booties and bunny suits in the clean rooms so that they don’t bring any contaminants into the room. Eating and drinking is also banned in cleanrooms.

What are the Different Types of Cleanrooms?

As cleanroom work is varied in nature, cleanroom facilities exist as portable, modular as well as fixed building structures. And modular cleanrooms, stick-built cleanrooms (or standard), and softwall cleanrooms are the most common types of cleanrooms.

In modular cleanrooms, prefabricated modular wall system is used which allow faster installation, easy modification(s), and reasonable cost. On the other hand, stick built or standard cleanrooms are dependent on conventional steel stud(s) drywall construction and are slightly cheaper. Whereas softwall cleanrooms make use of clear vinyl curtains which are suspended from metal frames.

Such portable cleanrooms can be assembled outdoors considering any existing facility such as warehouses. Modular cleanrooms are easy to modify, expand, or relocate in contrast with conventional construction cleanrooms.

Modular cleanroom is built using prefabricated modular components and for any classification (class 100-100k, ISO5-ISO8) with temperature and RH control. These clean rooms can be manufactured and installed 50% faster than stick built conventional construction clean rooms.

In softwall cleanroom, clear vinyl curtains are hanged on an aluminium frame to create walls. These are one pass clean rooms as they filter air pulled by HEPA fan filter units. The air passes under the curtain back into the surrounding room.

Softwall cleanrooms can be mounted on casters so that they can be easily moved around. Unlike recirculating modular cleanrooms, Air conditioning cannot be added to softwall clean rooms.
