Epack Prefab Clean Room Manufacturer

The purpose of a cleanroom is to control an environment by limiting the presence of sub-micron particles and modifying inadequate environmental conditions.

The level to which the environment is controlled is what separates one clean room from another.

For instance, a Class 10 cleanroom has 10 particles of size 0.5 microns per cubic foot of air, whereas a Class 100,000 cleanroom has 100,000 particles of size 0.5 micron per cubic foot of air.

The need for cleanrooms are in the sector electronic, Pharmaceutical, aerospace, food industries, medical and many other industries depend upon the cleanroom technology.

In electronics sector products like circuit boards become smaller and the chance of contamination in manufacturing become higher.

For Pharmaceutical companies, clean, safe and contaminant-free products are necessary for manufacturing and distributing a viable product.

The largest cause of contamination in a cleanroom is personnel. As per a report :

A person standing or sitting with no movement resulted in 100,000 particles/minute 0.3 microns or larger.
Sitting or standing, light head, hand, and forearm movement resulted in 500,000 particles/minute 0.3 microns and larger.
Sitting or standing, average body and arm movement, toe-tapping, resulted in 1,000,000 particles/minute, 0.3 microns and larger.
Changing positions, sitting to standing resulted in 2,500,000 particles/minute 0.3 microns or larger.
Slow walking 5,000,000 particles/minute 0.3 microns or larger .
Average walking 7,500,000 particles/minute 0.3 microns or larger.
Fast walking 10,000,000 particles/minute 0.3 microns or larger .
Climbing stairs 10,000,000 particles/minute 0.3 microns or larger .


The cleanliness of a cleanroom is measured by the size and number of dust particles in a given volume of air.

The rating or classification by the number of particles in a given volume of air and under specific conditions is called cleanliness level class.

Regulations may vary from country to country, but in most places, the national rule is established by referring to US Federal standard 209E by the number of particles with a diameter 0.5-micron meter or larger containers in one cubic meter of air.

ISO air cleanliness classifications-class limits (Particles/m3).
