Cleanroom Doors - How to Choose the Right Door for Your Cleanroom

Cleanrooms are sophisticated areas used for production of sensitive products. A cleanroom is a space that is highly controlled in terms of airflow, humidity, particles, and other factors. Cleanrooms are used in manufacturing to prevent outside contamination from entering the area and vice versa. They are also used in healthcare, pharmaceuticals, semiconductor manufacturing and other industries where contamination can result in dangerous conditions or failure for the product. Cleanrooms have strict rules about what can be brought into them and how people must dress when they enter. You cannot bring in anything that could transfer contamination into the cleanroom, such as clothing or hair clips. You also have to wear special gowns or jumpsuits with taped seams to ensure you don’t bring any particles inside with you. Cleanrooms often use HEPA filters to purify the air and keep it free of particles like dust and pet dander – which would trigger asthma attacks or allergic reactions if they were allowed in the area. If you work with sensitive products in a cleanroom environment this article will provide insight on different types of cleanroom doors that may be right for your facility.

What is a Cleanroom?

A cleanroom is a space that is highly controlled in terms of airflow, humidity, particles, and other factors to prevent outside contamination from entering the area and vice versa. They are often used in manufacturing to protect sensitive products like semiconductors, pharmaceuticals and medical devices. They are also used in healthcare, aerospace, and research facilities where contamination can result in dangerous conditions or failure for the product. Cleanrooms have strict rules about what can be brought into them and how people must dress when they enter. You cannot bring in anything that could transfer contamination into the cleanroom, such as clothing or hair clips. You also have to wear special gowns or jumpsuits with taped seams to ensure you don’t bring any particles inside with you. Cleanrooms often use HEPA filters to purify the air and keep it free of particles like dust and pet dander – which would trigger asthma attacks or allergic reactions if they were allowed in the area. Some cleanrooms are even kept under a partial vacuum to further reduce the amount of particles that can enter.

HEPA Filtration

HEPA stands for “high-efficiency particulate air” and describes a type of air filter that is very good at removing particulate matter from the air. HEPA filters do not kill bacteria or viruses, but they do prevent them from spreading through the air. They are often used to filter the air in cleanrooms and other areas where sensitive products are being created. A cleanroom door is equipped with a HEPA filter to prevent contaminants from entering the cleanroom and vice versa. A cleanroom is usually equipped with a dedicated ventilation system, so the filter will help to ensure the air remains clean inside the area. To be certified as a cleanroom, the air inside the room must have a maximum number of particles per volume of air. Those particles must also be as small as possible to prevent them from becoming airborne

Class 100,000 Cleanroom Door

A Class 100,000 cleanroom door is one that has been certified to filter 99.97% of particles from the air. A cleanroom door that is certified to this level is suitable for a Class 100,000 cleanroom. A cleanroom door that is Class 100,000 will also be rated for a cleanroom that is less strict – such as a Class 10,000 or Class 1,000 facility. A Class 100,000 cleanroom door has a filter that is certified to meet the ASHRAE Standard 52. There are three levels of filtration certification – UL, ASHRAE and ISO. Each level is more stringent than the last and will result in a cleaner atmosphere in the cleanroom. Cleanrooms are typically rated as Class 100,000, 10,000, or 1,000 facilities. A higher rating means the cleanroom requires more stringent control of the airflow and filtration. A Class 100,000 cleanroom will have stricter air control and a more advanced filtration system than a Class 10,000 cleanroom.

Class 10,000 Cleanroom Door

A Class 10,000 cleanroom door has been certified to filter 99.9% of particles from the air. A cleanroom door that is certified to this level is suitable for a Class 10,000 cleanroom. A cleanroom door that is Class 10,000 will also be rated for a cleanroom that is less strict – such as a Class 100,000 or 1,000 facility. A Class 10,000 cleanroom door has a filter that is certified to meet the UL Cleanroom Standard. The UL Cleanroom Standard requires a 95% reduction of particles in the air – which means there is still a small amount of air that makes it through the filter. Cleanrooms are typically rated as a Class 100,000, 10,000, or 1,000 facilities. A higher rating means the cleanroom requires more stringent control of the airflow and filtration. A Class 10,000 cleanroom will have a less advanced filtration system than a Class 100,000 cleanroom. A Class 1,000 cleanroom will have a less advanced filtration system than a Class 10,000 cleanroom.

Class 1,000 Cleanroom Door

A Class 1,000 cleanroom door has been certified to filter 99% of particles from the air. A cleanroom door that is certified to this level is suitable for a Class 1,000 cleanroom. A cleanroom door that is Class 1,000 will also be rated for a cleanroom that is less strict – such as a Class 10,000 or 100,000 facility. A Class 1,000 cleanroom door has a filter that is certified to meet the ISO Standard 17387. The ISO Standard 17387 requires a 5% reduction of particles in the air – which means there is almost no air that makes it through the filter. Cleanrooms are typically rated as a Class 100,000, 10,000, or 1,000 facilities. A higher rating means the cleanroom requires more stringent control of the airflow and filtration. A Class 1,000 cleanroom will have a more advanced filtration system than a Class 100,000 cleanroom.

Conclusion

A clean room is a space that is highly controlled in terms of airflow, humidity, particles, and other factors to prevent outside contamination from entering the area and vice versa. They are often used in manufacturing to protect sensitive products like semiconductors, pharmaceuticals and medical devices. They are also used in healthcare, aerospace, and research facilities where contamination can result in dangerous conditions or failure of the product. Cleanrooms have strict rules about what can be brought into them and how people must dress when they enter. You cannot bring in anything that could transfer contamination into the cleanroom, such as clothing or hair clips.

Cleanrooms often use HEPA filters to purify the air and keep it free of particles like dust and pet dander – which would trigger asthma attacks or allergic reactions if they were allowed in the area. A higher cleanroom rating indicates more stringent control of the airflow and filtration.
