1. Laminar flow pass box description
The laminar flow pass box is mainly used in the biological clean
area as the transfer of goods. The main application places are:
bio-pharmaceuticals, scientific research units, disease control
centers, large hospitals, university research, biological cleansing
and application of various clean areas.
2. Clean laminar flow pass box basic performance repquirements
1). Cleanliness requirements in the laminar flow transfer window:
Class B.
2). Inside and outside double-layer shell, the inner circumference
of the arc treatment, to ensure seamless connection.
3). Laminar flow design is adopted, the airflow direction adopts
the upper-feed-down mode, and the bottom adopts the 304 stainless
steel cold-rolled plate punching design, and the reinforcing rib is
set.
4). Filter: The primary filter adopts G4, and the high efficiency
filter adopts H14.
5). Wind speed: After the high-efficiency filter, the wind speed is
controlled at 0.38-0.57m/s (tested 150mm below the high-efficiency
airflow equalizer).
6). Differential pressure function: display filter pressure
difference (range efficiency 0-500Pa / medium effect 0-250Pa),
accuracy ± 5Pa.
7). Control function: fan start/stop button, configure built-in
electronic door interlock; set UV lamp, design separate switch,
when the two doors are closed, the UV lamp should be in the open
state; set the lighting, design a separate switch .
8). The high-efficiency filter can be separately removed and
installed from the upper box for easy maintenance and replacement
of the filter.
9). Set the inspection port at the lower part of the transmission
window for maintenance of the fan.
10). noise: the noise of the transmission window during normal
operation <65db.
11). Efficient airflow averaging plate: 304 stainless steel
stencil.
