A cleanroom is a space in which the level of environmental contaminants is controlled. They can mostly be found in manufacturing and scientific research facilities where the environment needs to have a measurably low level of airborne particles, chemicals and bacteria. This is achieved through a combination of measures like Airflow, which is controlled using ultra-low penetration air (ULPA) and/or high-efficiency particulate air (HEPA) filters, the room is constructed using carefully selected materials that will not produce or retain environmental contaminants.

This includes air-locked entrances and exits and all individuals using the room must be appropriately dressed using coveralls, hoods, gloves, boots and face-masks. Let's look at some of the equipment needed during the set up. HEPA and ULPA filters: HEPA filters use a randomly constructed mat of fibers that filters out 99.97% of particles that are greater than 0.3 microns in diameter. ULPA filters remove 99.999% of particles greater than 0.12 microns in diameter.

These filters are used to maintain near-constant air processing that pushes airborne particles down towards the floor where they are trapped by filters and sucked out of the room. Having a job in a clean room does not mean you worked hard to clean your room at home. A clean room is an environment that is set to be free from dirt, germs and several other contaminants.

Variety of industries uses these facilities to manufacture and assemble items that must be produced in a specific and precise manner. HVAC systems: HVAC stands for heating, ventilation and air conditioning. These systems are used to control the temperature and humidity of the cleanroom. Most rooms require constant cooling due the heat produced by the air filtration devices, the lighting and the working processes.

The heat level must also be controlled to maintain a comfortable working temperature for staff members. Often wearing protective coveralls over their clothes, workers require a temperature range of 72-75F. Similarly, humidity control is required to avoid corrosion of materials, condensation on work areas and to maintain personnel comfort. A comfortable humidity range for workers is between 30 and 70%.
