Dynamic Cleanroom Pass Box Clean Laminar Flow Type Mechanical / Electronic Interlock

1. Dynamic 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.Dynamic pass box features

1). The inner and outer surfaces and frame of the laminar flow pass box are 304 stainless steel cold-rolled plates, the thickness of the plate is ≥1.5mm, the surface is polished, and the surface finish should not be lower than RA1.2;

2), the frame of the laminar flow pass box is 304 stainless steel, the thickness is ≥1.2mm, the surface is polished, the surface finish should not be lower than RA1.2;

3). The window of the laminar flow transmission window is made of tempered glass, and the thickness of the tempered glass is ≥8 mm;

4), rounded corners: 304 stainless steel, thickness ≥ 1.2mm, the surface finish after polishing should not be less than RA1.2;

5). The Hepa filter frame is made of aluminum alloy;

6). The hepa filter air diffuser is made of 304 stainless steel mesh plate, the thickness of the plate is ≥1.0mm, and there must be no burrs.

3. Dynamic pass box basic performance repquirements

1). Cleanliness requirements in the laminar flow pass box: 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.
