Cleanroom Cleaning
A cleanroom is an enclosed space where strict contamination control is maintained.
In other words, the level of aerosol particles and airborne microorganisms in the
air is controlled to stay within the limited cleanliness level. There is also required
degree of cleanliness maintained for the objects inside the room such as
equipment, chemicals, and water supplied to the room. If necessary,environmental conditions like temperature, humidity and pressure are managed
carefully as well.
At Sanipro, we offer specialized cleaning services from post-construction total
cleanup to daily and periodic cleaning, customized to fit the use and requirementof cleanliness degrees.

Types of Cleanroom (Intended use)

Key Purpose of Cleanroom Cleaning
Particles and dust accumulated on the floor become scattered repeatedly as
workers walk.
This type of cleaning is not intended for aesthetics appeal, but for reducing the riskof pollution and contamination of the products, by maintaining cleanliness degree.

Types of Cleanroom Cleaning<Daily Cleaning>
For places where the risk for contamination is high, particularly where personnel
movement and activities are active (e.g. changing area, entry/exit area, etc.). To
prevent the accumulation and spreading of possible pollution (particles and dust)that could contaminate the cleanroom, it is strongly advised to frequently performthe cleaning.
Target areas: floor, door, pass box, air shower<Periodic Cleaning>
For places where it is difficult to perform daily cleaning, with lower level ofcontamination risk. The frequency of cleaning should be rather low accordingly.
Target areas: wall surface, ceiling surface, ducts/pipes, lighting fixture, etc.
<Specialized Cleaning>
Cleaning at contaminated state such as building post-construction or renovation. It
is strongly advised to perform gradual cleaning until the cleanliness reaches theacceptable level.
Rough cleaning (removal of coarse particle contamination of particle size
exceeding 50 μm
particle size 10 μm ~ 50 μm
contamination of particle size less than 10 μm)
