What is a cleanroom?

A cleanroom or clean room is a well-planned space, which sustains a very low concentration of airborne particulates. It is well insulated, well-controlled from contamination, and dynamically cleansed.

How Will You Use It?

Cleanroom Environment Protocols: 

1. Leave personal things outside the controlled environment.
2. Do not wear makeup, scent, etc. inside the cleanroom.
3. Do not smoke, eat or chew gum inside the cleanroom.
4. Do not run or move hurriedly than needed within the controlled environment.
5. Do not enter the cleanroom if you’re sick or unwell.
6. Follow proper gowning and ungowning processes.
7. Practice good personal cleanliness.
8. Cover hair and facial hair.
9. Do not smoke before entering the cleanroom.
10. Do not sit or lean on work surfaces or equipment.
11. Do not touch your face or hair with gloved hands.

How Should It Be Classified?

Cleanrooms are classified according to the size and number of particles allowed per volume of air. Large numbers like “class 100” or “class 1000” refer to FED-STD-209E, and signify the number of particles of size 0.5 μm or larger allowable per cubic foot of air.

What are the ventilation types of a cleanroom? 

Cleanrooms have advanced into two most important types and they are distinguished by their method of ventilation. These are turbulently ventilated and unidirectional flow cleanrooms. Turbulent ventilated cleanrooms are also known as ‘non-unidirectional’. Unidirectional flow cleanrooms were initially known as ‘laminar flow’ cleanrooms. The unidirectional kind of cleanroom uses very much more air than the turbulently ventilated type, and gives a superior hygiene.

When Is a Cleanroom Required?

Medical device and pharmaceutical manufacturing needs sterilized environments to produce their products. Cleanrooms offer this sterile super clean manufacturing space which decreases the chance of contamination getting in your medicine. Semiconductor manufacturers manufacture devices with ultra-small super dense features. For example, the computer chips for a cell phone or PC. If contamination were to get on the chip during the manufacturing process, they would not function properly.

How Air is Purified in a cleanroom?

Cleanroom air is strictly purified using high-efficiency particulate attenuation (HEPA) filters to remove airborne particles, ionizing grids to neutralize static that draws particles, and heating, ventilating, and air conditioning (HVAC) equipment to exhaust air and particles outside the cleanroom and conserve positive cleanroom air pressure.

What Lighting Do You Require?

Most cleanroom lighting uses a fluorescent lamp because they are energy proficient, easy to maintain and have a long lifecycle, but other kinds of lighting are applicable in clean rooms as well. Incandescent, high intensity lamps and LED lighting fixtures are used in cleanroom lighting applications.

What Flooring Do You Require?

Epoxy flooring
Epoxy flooring can endure high temperatures (up to 158°F) because it absorbs and transfers heat, which means the floor can be hygienically steam cleaned without any affecting or any degradation in the surface. They can withstand extremely cold temperatures without any adverse effect on its durability, making it the ideal choice for freezers or chiller areas in which test samples are stockpiled.

What is the basic structure of cleanrooms?

Each cleanroom environment has different installation settings and requirements. Depending on those, the solution can feature foil curtains (softwall) or solid wall elements (hardwall) and equipment provided in different sizes.
