I. Use of Industrial pass box
Dynamic pass box is a clean air auxiliary equipment, mainly used for the transfer of small items between clean areas and clean areas, clean areas and non-clean areas to reduce the number of open doors in the clean space, so as to ensure the cleanliness requirements in the clean space.
II. Working principle
The air in the active pass box is mainly used for circulation, the air is quickly blown out of the air filtered by the primary efficiency filter and the fan, and then becomes clean real gas through the HEPA filter unit. The clean air is ejected at high speed from the spherical air nozzle, and the air passage speed is up to 20m/s or more, which can effectively remove the dust particles attached to the surface quickly. The air containing the dust is then sucked into the primary efficiency filter.
III. Structural characteristics
Cleanroom pass box can be used in two structural forms of color steel and stainless steel, the surface of strict oil removal, rust removal, phosphating treatment and then spray, beautiful appearance, and can be disassembled after on-site assembly, more conducive to transportation and ensure product quality. Fan to use low noise high pressure high efficiency fan and time relay control system combined to ensure the necessary wind speed and save power consumption. The high-speed ball nozzle configuration is scientific and reasonable, which can ensure the best air shower effect.
