Inflatable sealed airtight doors are mainly used in rooms with airtight requirements in high-level biosafety laboratories (BSL-3, BSL-4, ABSL-3, ABSL-4), which can solve the problem of door airtightness.
Inflatable sealed airtight doors are divided into single airbag and double airbag inflatable sealed airtight doors, among which the double airbag inflatable sealed airtight door has on-site airtightness self testing function. The working principle is that when the door is opened, the inflatable sealing strip deflates and contracts in the groove. When the door is closed, the inflatable sealing strip inflates and expands to form a strict seal between the door and the door frame, while the door is tightly locked. The fully sealed airtight door has excellent airtight performance, with a seamless stainless steel welding structure that is resistant to corrosion from disinfectants such as formaldehyde, vaporized hydrogen peroxide, and gaseous chlorine dioxide. It can be used independently or in combination with multiple sets, and has the characteristics of single door control or multi door interlocking, making it safe and reliable.
performance index
1. Structural stress resistance:> 2500Pa;
2. The inflation and deflation time of the inflatable sealing strip is ≤ 5 seconds;
3. The number of times to inflate and deflate the inflatable sealing strip is 10000 times;
4. Airtightness: The airtight space can be kept airtight at a pressure of ± 500Pa, with a leakage rate of less than 0.25% vol/h;
5. Safety redundancy: Both sides of the airtight door are equipped with emergency stop buttons and manual release valves, which can effectively prevent the airtight door from being unable to open due to electrical or pneumatic faults;
