A cleanroom requires certain many different aspects to help keep it functioning properly.

2. Why do you need a cleanroom
• A cleanroom is a controlled space where work
can be carried out in a controlled,
contaminant-free condition
• This sealed environment is important to
specific fields
• Cleanrooms are used in two main applications

3. Electronics manufacturing
• Silicon chips and other electronic components are
extremely sensitive and must conduct electricity
perfectly through an elaborate system
• Dust can negatively impact these electrical
systems
• All computers contain parts made in these very
cleanrooms

4. Pharmaceuticals
• The production of medical drugs as well as
other bio science research and manufacturing
must be done in a totally contaminant free
environment
• Keeping the products clean is
essential to this industry

5. Requirements for a cleanroom
• A cleanroom requires many aspects to help
prevent any type of contamination
• Here are a few requirements:
– Filters for outside air − Internal recirculation filters
– Climate control − Air pressure
– Airlocks

6. Filters for outside air
• All air coming into a cleanroom must be
thoroughly filtered so it does not pass
contaminants into the protected space
• Contaminants include dust and tiny particles
that are common in normal air
• Filters are also used to attain the highest level
of purity

7. Internal recirculation filters
• Air within a cleanroom can pick up particles
created by work processes, as well as tools
and furniture
• Filtered air within the room is continuously
circulated through additional filters to scrub it
of internal contaminants

8. Climate control
• Temperature and humidity can affect sensitive
materials and must be controlled
• Air within a cleanroom is kept at a constant
temperature and normally at very low
humidity levels
• Ionic dehumidifiers are a good way to help
avoid any possible contamination

9. Air pressure
• For a cleanroom there are processes that require
positive or negative air pressure so that the room
can be controlled if need be
• In addition positive air pressure means that
particles in the entrances/exits tend to push air
away from the cleanroom
• This air pressure will help keep any particles from
entering with personnel

10. Airlocks
• Any personnel that enter a cleanroom must go
through airlocks
• Airlocks are multi-stage airtight sally ports that
allow unfiltered outside air to be drained from
the airlock chamber
• This air is replaced with clean air before the
personnel can enter. Some cleanrooms have high
air pressure to blast particles off of personnel as
they enter

11. Cleanroom requirements
• Making sure that your cleanroom is
uncontaminated is crucial
