Scope of Application

【Operating Instructions】

Air is drawn through a pre‑filter (primary efficiency filter) on the side and a low‑noise centrifugal fan into a plenum chamber. It then passes through a high‑efficiency particulate air (HEPA) filter and is uniformly blown out from the top, forming a high‑cleanliness air curtain that displaces the original ambient air in the work zone. Within five minutes of startup, an ideal high‑cleanliness space is achieved. A two‑speed adjustable fan is used to regulate the airflow volume via a touch‑type switch, ensuring that the air velocity in the work zone remains at an optimal level at all times.

【Scope of Application】

Air is drawn through a pre‑filter (primary efficiency filter) on the side and a low‑noise

 centrifugal fan into a plenum chamber. It then passes through a high‑efficiency particulate air (HEPA)

 filter and is uniformly blown out from the top, forming a high‑cleanliness air curtain 

that displaces the original ambient air in the work zone. Within five minutes of startup, an ideal

 high‑cleanliness space is achieved. A two‑speed adjustable fan is used to regulate the 

airflow volume via a touch‑type switch, ensuring that the air velocity in the work zone remains 

at an optimal level at all times.

**【Instrument Features】**  

1. Horizontal (vertical) flow design, semi‑closed glass sash — convenient to operate.  

2. Can be placed on a standard workbench for operation, making it suitable 

for small laboratories.  

3. Uses a two‑speed (fast/slow) fan control system to keep the air velocity in 

the work zone at an optimal level.  

4. The workbench is equipped with spring‑assisted upper and lower sliding doors

 at the front and rear for flexible and convenient positioning.  

5. Air curtain isolation design prevents cross‑contamination between the interior and exterior.  

6. PVC work surface more effectively maintains cleanliness.
