What Is the Difference Between Negative and Positive Pressure Cleanrooms

You may wonder why cleanrooms utilize different pressure types. The distinction between Negative Pressure vs. Positive Pressure Cleanrooms lies in how air circulates. Each type manages contamination in its unique manner. Positive pressure cleanrooms expel clean air, preventing outside particles from entering. In contrast, Negative pressure cleanrooms draw air inward, effectively trapping harmful particles within the room. Maintaining pressure control is essential for minimizing contamination. Research indicates that smaller leaks and optimal airflow contribute to maintaining significant pressure differentials, which safeguard sensitive environments:

Amber’s solutions incorporate these principles to assist you in creating safe, controlled environments.

Negative Pressure vs. Positive Pressure Cleanrooms

Core Difference

Airflow Direction

Airflow moves differently in these cleanrooms. In a positive pressure cleanroom, air pressure inside is higher than outside. Clean air leaves the room through doors and small cracks. This stops outside air and particles from coming in. In a negative pressure cleanroom, air pressure inside is lower than outside. Air from outside comes into the room. This keeps harmful particles and contaminants trapped inside, so they cannot get out.

Tip: The way air moves in each cleanroom helps you control contamination and protect sensitive places.

Contamination Control

You use positive pressure cleanrooms to keep bad things out. These rooms push clean air out, so dust and germs stay away. You use negative pressure cleanrooms to keep dangerous things inside. These rooms pull air in, so harmful particles do not leave. Hospitals use negative pressure cleanrooms to keep sick patients apart. Labs use them to stop dangerous germs from spreading. Drug makers use negative pressure cleanrooms to keep harmful materials inside.

Pressure Principles

You can see how pressure works in the table below:

Positive pressure cleanrooms have more pressure inside than outside. This keeps bad things from getting in. Negative pressure cleanrooms have less pressure inside. This lets air come in and keeps harmful things from leaving.

You need a strong ventilation system to keep the pressure steady. The ventilation system moves air in and out to keep the air clean. In positive pressure cleanrooms, the system pushes clean air out. In negative pressure cleanrooms, the system pulls air in and keeps harmful particles inside.

You find positive pressure cleanrooms in drug factories, microelectronics, and medical device plants. These rooms protect products from outside dirt. Negative pressure cleanrooms are used in research labs, chemical plants, and quarantine areas. These rooms stop dangerous things from escaping.

Maintenance and Challenges

Pressure Stability

You have to keep the pressure steady in your cleanroom. If the pressure changes, dirt can get in or bad particles can get out. Many things can mess up the pressure. If doors do not close right, dirty air can sneak in. Sometimes, sensors do not work right and give wrong numbers. Machines can break and stop the air from moving like it should.

Here is a table that shows some common problems:

You need to check your filters and HVAC systems often. Change filters when they get dirty. Make sure the air always moves the same way. Put air diffusers and return grilles in the best spots. This stops dead spots and keeps air moving everywhere.

To keep pressure steady, move air from high-pressure to low-pressure rooms. This makes a wall that blocks dirt. Some factories use cascade pressure systems. These systems keep the most important rooms at higher pressure to protect products.

Air Leakage

Air leaks can make your cleanroom not work right. In positive pressure cleanrooms, air should go out. In negative pressure cleanrooms, air should come in. Leaks near doors or windows can mess up this flow. You lose control of pressure and risk getting dirt inside.

You can do these things to stop air leaks:

• Check and change HEPA filters often.

• Pick where people go in and out.

• Use the right packaging and clean items before bringing them in.

• Watch the room with monitors all the time.

• Teach workers about where dirt can come from.

• Keep air leaks at 1-2% to keep the cleanroom safe.

• Close up gaps and extra exits in the building.

You must keep air moving the right way. This helps keep products safe and protects people.
