Cleanrooms are tightly controlled environments used in various industries, such as pharmaceuticals, biotechnology and healthcare. The key objective of cleanrooms is to minimize particulate contamination and maintain specific levels of cleanliness. To achieve this goal, every component within a cleanroom must be carefully designed and specified, including the doors. Cleanroom swing doors play a vital role in maintaining the integrity of cleanroom environments by preventing the entry of contaminants while allowing access for personnel and equipment.

Specialized cleanroom doors are designed with meticulous attention to detail, considering factors such as air leakage prevention, durability, ease of cleaning, and compliance with stringent industry standards.

Key Features of Cleanroom Swing Doors

Cleanroom swing doors offer a range of key features and benefits that make them an ideal choice for controlled environments. Firstly, these doors are designed with airtight seals, ensuring minimal air leakage and maintaining the desired level of cleanliness within the cleanroom. This helps to prevent contamination and maintain sterile conditions. Furthermore, cleanroom swing doors are constructed using materials that are resistant to chemicals, making them highly durable and long-lasting.

Their smooth surfaces also make them easy to clean, reducing the risk of particle accumulation. Additionally, these doors can be equipped with interlocking systems to control access and enhance security. Another advantage of cleanroom swing doors is their ability to provide excellent sound insulation, minimizing noise pollution in sensitive work areas. Moreover, they are available in various sizes and configurations to suit different requirements.

Types of Cleanroom Swing Doors Available

Cleanroom swing doors are an essential component of controlled environments, ensuring the highest level of cleanliness and preventing contamination. Various types of cleanroom swing doors are available, each designed to meet specific requirements and standards. Firstly, flush cleanroom swing doors are widely used for their sleek appearance and seamless integration into the cleanroom walls. These doors have a completely flat surface without any protrusions or ledges, minimizing particle accumulation and facilitating easy cleaning.

Secondly, fire rated cleanroom doors provide an added layer of safety by offering fire resistance for a specified duration. These doors are constructed with special materials that can withstand extreme temperatures and prevent the spread of fire within the cleanroom. Moreover, double-leaf cleanroom swing doors allow wider access points while maintaining cleanliness standards. These doors consist of two independent leaves that can be opened simultaneously or individually, providing convenience in high-traffic areas.

Factors to Consider When Choosing Cleanroom Swing Doors

When selecting cleanroom swing doors, several crucial factors need to be taken into consideration. First and foremost is the door’s material. The chosen material should be compatible with the cleanroom environment, ensuring easy cleaning and preventing particle contamination. Secondly, the door’s design and construction must provide an airtight seal when closed, maintaining the desired pressure differentials inside the cleanroom. Additionally, considering the frequency of use is important as it affects durability and maintenance requirements.

Swing doors should be designed for smooth operation and withstand constant opening and closing without compromising cleanliness levels. Another factor to consider is the size of the door. It should be appropriately sized to accommodate equipment or personnel traffic while minimizing air exchange during entry or exit from the cleanroom. Furthermore, compatibility with access control systems may also be crucial, enabling secure entry while preventing unauthorized access.

A Case Study From When We Supplied Cleanroom Swing Doors

We’ve collaborated with The Jefferson Institute for Bioprocessing in the United States on a couple of occasions. Initially, when they were inaugurated in 2019, we provided them with our cleanroom swing doors. In 2023, they had a similar requirement, and we were pleased to supply them with the same once again as well as a few other products like cleanroom windows and pass-through hatches.
