What Is Required for Clean Room Construction?
  • Opening Intro -

    A clean room is a highly controlled work space that keeps dust, microbes, and other particles out of the environment.

    Many industries rely on these rooms to produce high-quality materials free of any contamination.

Laboratories, pharmacies, and electronic manufacturers are among several sectors that need these specialized areas to complete their work. However, many people might wonder, “What is required for cleanroom construction?”

If you’re curious about the ins and outs of this interesting architectural concept, read on to learn more.

HEPA Filters

HEPA stands for “high-efficiency particulate air.” A HEPA filter is a type of pleated mechanical air filter. This type of filter removes almost 100% of impurities from the air in a clean room and can catch microscopic particles before they enter the environment.

HEPA filters often work alongside a specialized HVAC system to keep the air fresh and clean. Clean rooms need these strong filters so that microbes don’t damage any sensitive materials or products.

Room Design

One of the requirements for clean room construction is laminar flow, which refers to air that travels unimpeded by various structures.

This is important to clean rooms because restricted airflow may cause turbulence, which in turn kicks up particles that could be harmful to the environment.

Clean room designers fight this issue through careful design and architecture, which allows air to flow in one uniform direction.

ESD Protection

Electrical charges occur when two surfaces rub together and create friction. Any kind of movement can generate a charge, from air moving to simply walking across the floor.

ESD (electrostatic discharge)-protected materials minimize this occurrence. You can find these types of materials all over clean rooms and their staff in the form of specialized gloves, shoes covers, drapes, and cleaning supplies.

Pressurization

Pressure is a huge factor in the construction of a clean room. Typically, the internal pressure should be higher than atmospheric pressure to maintain a controlled environment.

Factors such as leaks and opened doors can change the pressure and allow clean air to escape, leaving unfiltered air to wreak havoc in the room. Staff can only alter pressure requirements when dealing with hazardous materials that require a negative pressure.

HVAC Systems

Clean rooms have to follow specific heating, cooling, and ventilation guidelines, all of which specialized HVAC systems control. Clean room HVAC requirements control temperatures, reduce humidity, and ensure airflow remains consistent. They also help in the ventilation process by properly removing old air and replacing it with fresh, filtered air.

Depending on the type of work, clean rooms in different industries may have more specific requirements for their HVAC systems.

When designing a clean room, professionals need to take all of these factors into consideration.

An unmaintained clean room compromises the integrity of the projects staff members are working on. Since these controlled environments are where experts make crucial products such as medicines and health-care equipment, it’s important to take construction matters seriously.

Ultimately, by following specific guidelines and keeping up with regular maintenance, you can rest easy knowing your environment is as sterile as it can be.
