Definition: Dynamic pass box is a type of purification equipment designed to transfer materials, equipment and tools between rooms of different cleanliness levels or different differential pressure gradients.
Operation principle: Dynamic pass box delivers air at specified air speed through HEPA filter, makes the air homogeneously compressed by damping layer, and then leads the clean air unidirectional flow to the work area, thus achieving the flow pattern and cleanness required in the protected work area.
Type: Positive pressure, negative pressure or gradient pressure.
Installation method: Land mounted or wall mounted.
Applications: Micro-electronics, science laboratory, precise instrument, pharmaceuticals, micro-organism studies, aseptic packaging, etc.
1. Panel electronic interlock, good reliable.
2. Integrated circular arc design for the working area,no dead angles, easy to clean.
3. Double negative pressure construction, no leakage risk.
4. Corner type, three-door type, double-layer type and other many different types for option.
