The design of fast doors in cleanrooms needs to meet specific requirements to ensure the cleanliness and safety of the indoor environment. Below are a few special requirements for the design of fast doors in cleanrooms.

1.Sealing: Cleanroom fast doors must have good sealing performance to prevent external contaminants from entering the room. The door body will usually be designed around the airtight strip or brush strip, as well as special sealing devices to ensure that there is no gap when the door is closed.

2.Rapid opening and closing: the cleanroom needs a fast door to be able to open and close quickly in a short period of time, in order to reduce the pollutants brought into the door when people enter and exit, but also to facilitate the rapid passage of logistics.

3.Material selection: the door body material should be selected as corrosion-resistant, easy-to-clean and not easy to accumulate dust, such as stainless steel, aluminium alloy or special dust-proof material, in order to maintain the hygienic state of the clean room.

4.Driving system: The driving system of the fast door usually adopts servo motor to ensure the smoothness and precise control of the door operation. The motor should be built-in or hidden inside the door body to reduce external interference and maintenance.

5. Safety features: cleanroom fast doors need to be equipped with a variety of safety devices, such as infrared sensors, magnetic rings, airbags, etc., in order to protect the safety of personnel and equipment. 

6.Interlocking function: In order to enhance the safety of the cleanroom, the fast door usually need to have interlocking function, that is, when a door is open, another door is closed to ensure that the personnel or materials can only one-way pass.

7. Anti-static: in some demanding cleanrooms, the door body and accessories also need to have anti-static properties to prevent static discharge damage to the product and the environment. 

8.Maintainability: The design should take into account the maintenance and cleaning of the door body. Components such as door curtains, tracks and seals should be easy to remove and replace to facilitate routine maintenance.

9. Compatibility: The cleanroom fast door should be compatible with other equipment and systems in the cleanroom (e.g. air shower room, cargo shower room, central air-conditioning, etc.) to ensure the coordinated operation of the whole system.

10. automation control: cleanroom fast door usually need to be integrated with automation control system, such as PLC control, in order to achieve precise control of door opening and closing, speed and safety.

In summary, the design of cleanroom fast doors requires comprehensive consideration of many aspects such as cleanliness, safety, reliability, ease of use and maintenance to ensure that the stringent environmental requirements of cleanrooms are met.
