       1. It adopts a three-stage exhaust structure to effectively discharge harmful gases.
       2. Streamlined handle, leaving a gap between the handle and the glass. Since the air flow on the table top rotates, effective air intake is ensured from the surface.
       3. Set the window anti-falling pin. If the wire rope falls off and the glass window falls accidentally, the anti-falling pin will catch it and prevent people from being injured.
       4. The glass window is made of tempered glass. Even if the glass is accidentally damaged or exploded, no injuries will occur.
       5. Ventilation holes are set on the upper part of the fume hood so that air can enter even if the glass window is closed to avoid large negative pressure.
