Laminar Flow Pass Box (Dynamic)
Laminar Flow Pass Box (Dynamic) ensures contamination-free material transfer between cleanrooms or controlled environments. Equipped with HEPA filters and a dynamic airflow system, it maintains ISO Class 5 cleanliness, making it ideal for pharmaceutical labs, biotechnology facilities, and electronics manufacturing. Key features include HEPA filtration (99.99% efficiency), dynamic airflow for positive pressure, UV sterilization, and customizable sizes. Perfect for cleanroom material transfer, contamination-free workflows, and laboratory safety, this pass box is a must-have for ISO-compliant facilities.
Laminar Flow Pass Box (Dynamic)
The Dynamic/laminar flow pass box are aseptic architectural systems used to prevent contaminants from leaking into aseptic suites. They are utilized for aseptic transfer of materials into and out of the critical process environments.
PRINCIPLE
·Dynamic airflow provides an air barrier to prevent contaminants from entering into critical controlled environments during material transfers
·Vertical purging to trace any contaminants that have potentially entered post material transfer.
·Unit operates with a recirculating airflow and on-board fans hence, external ducting is not required.

FEATURE
Easy to clean design
Material of construction is full stainless steel with interior rounded/coved corners at its base which is easy to clean.
Construction
The inner and outer double-layer shell, the inner circumference is arc treated, and the connection is seamless. It adopts laminar flow design, the airflow direction adopts the upper and lower return mode, and the bottom adopts the punching design of 304 stainless steel cold car plate, and sets up reinforcing ribs.
Simple switches
Fan start/stop button, configure built-in electronic door interlock, set UV lamp, design separate switch.
Interlocking doors
Electromagnetic interlocking doors to prevent both doors from being opened at the same time
Full stainless steel construction
Differential pressure function
Display the pressure difference of the filter (range high efficiency 0-500Pa), accuracy +5Pa;
Air velocity
After passing through the HEPA filter, the outlet air velocity is controlled at 0.36-054m/s. (tested at 150mm below the HEPA outlet air flow plate):
Difference between air shower pass box and laminar flow pass box
The interior of the air shower pass box can only reach a purification effect of 1,000 grades due to its structure and wind speed, and a basic requirement of the laminar flow pass box is to be at least 1,000, and the highest can reach 100and 10 grades or even 1 grades.
In the management requirements of the new version of GMP in the pharmaceutical industry for the transfer window, because many production workshops are grade 100 or even ten areas, in order to avoid the impact of the transfer material on the clean room, the requirements of the new version GMP for the transfer window are much higher than before. Therefore, the function of the previous air shower transfer window does not meet the requirements, and the laminar flow transfer window must be used to avoid polluting the production environment; the new version of the GMP transfer window is strictly in accordance with the self-cleaning time, and the items cannot be removed without reaching the self-cleaning time, so as to achieve GMP Management requirements.
Therefore, the most important problem in choosing these two delivery windows depends on where they are used.
