The cleanroom HVAC controls the temperature and the humidity to your appropriate levels of precision, similar to standard HVAC. The increased air supply brings more air changes per hour with new HEPA filtered air circulating into the cleanroom many times per hour.

What is a Class 8 clean room?

ISO 8 cleanrooms, also known as Class 100,000 cleanrooms, can be modular or soft-walled and have a maximum particle count of 100,000 particles (≥0.5 um) per cubic foot of interior air.

How do you calculate air flow?

By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured in Cubic Feet per Minute (CFM). Concept of Air Velocity can be used in air conditioning, heating and ventilating work.

How do you create a clean room?

Clean room design encompasses much more than traditional temperature and humidity control. Design must consider aspects such as control of particulate, microbial, electrostatic discharge, gaseous contaminants, airflow pattern control, and pressurization and industrial engineering aspects.

What is not allowed in a clean room?

Personal Actions Typically Prohibited in Cleanrooms Fast motions such as running, walking fast or horseplay. Sitting or leaning on equipment or work surfaces. Writing on equipment or garments. Removal of items from beneath the cleanroom garments.

Are clean room positive or negative pressure?

Negative air pressure is used in cleanrooms where the goal is to keep any possible contamination from escaping the cleanroom. Windows and doors have to be completely sealed, and by having a lower pressure, air outside the cleanroom is likely to flow into it, rather than out of it.

How do you count particles in a clean room?

To do this you will need this formula: Vs = 20/Cnm) x 1000. Vs is the minimum single sample volume per location. Cnm is the class limit for the largest considered particle size specified for the class of your cleanroom. 20 is the defined number of particles that could be counted for class of the cleanroom.

Why clean room is yellow?

Cleanroom used for the production of microsystems. The yellow (red-green) lighting is necessary for photolithography, to prevent unwanted exposure of photoresist to light of shorter wavelengths.
