How many types of Biosafety airtight doors are for the cleanroom?

There are two primary types of biological safety airtight doors: mechanical compression airtight doors and inflatable airtight doors.

Inflatable airtight doors

The inflatable airtight door consists of key components such as a door frame, door panel, inflatable sealing strip, and a control system. The inflatable sealing strip is specifically installed within the groove surrounding the door.

When the door is opened, the inflatable sealing strip retracts or shrinks within the groove. This allows for unobstructed passage and easy access through the door.

When the door is closed, the inflatable sealing strip automatically inflates to its designated size. This inflation process creates a tight seal between the door and the door frame, ensuring an airtight barrier. Simultaneously, the door securely locks into place, providing additional security and stability.

The inflatable sealing strip plays a vital role in achieving an effective seal. When the door is closed, it expands and fills the space between the door panel and the door frame, creating a secure and tight barrier against air leakage and the intrusion of contaminants.

The control system of the inflatable airtight door manages the inflation and deflation of the sealing strip. It ensures the precise timing and control of the inflation process, allowing for a reliable and consistent seal each time the door is closed.

The mechanical compression airtight door

The mechanical compression airtight door consists of essential components such as a door frame, door body, sealing strip, mechanical compression mechanism, and control device. The sealing strip is specifically installed on the door frame, ensuring a precise fit.

When the mechanical compression airtight door is closed, the sealing strip is tightly pressed against the edge of the door frame. This mechanism creates a secure and strict seal between the door and the door frame, preventing any potential leakage or infiltration of air or contaminants.

The door frame provides structural support and serves as the framework for the door assembly. It ensures stability and proper alignment during the opening and closing of the door.

The door body, which is attached to the door frame, forms the physical barrier of the airtight door. It is designed to be sturdy and durable, capable of withstanding pressure differentials and maintaining the integrity of the controlled environment.

The sealing strip plays a crucial role in achieving a tight seal. It is strategically positioned on the door frame and functions as a barrier against air leakage. When the door is closed, the sealing strip is compressed against the door frame, creating an airtight seal that prevents the escape or entry of air and contaminants.

The mechanical compression mechanism is responsible for applying pressure to the sealing strip. It ensures a consistent and uniform compression force along the door frame, maintaining a reliable and secure seal.

Lastly, the control device enables the smooth operation and control of the mechanical compression airtight door. It allows for manual or automated control, ensuring precise alignment, proper compression, and reliable sealing.
