1. What is a laminar air flow unit?
- Laminar air flow unit is also called a laminar flow hood, laminar flow cabinet or compounding hood.
- Laminar flow hood is an air purification equipment that provides Class A unidirectional flow and creates a local high cleanliness environment.
2. Why do we need a laminar air flow unit?
- Laminar flow hood is one of the equipment that can shield and isolate operators from products. Its main purpose is to avoid product contamination.
- It is an ideal equipment for achieving high purification level requirements in low purification areas.
- It is mainly used to protect the production process of sterile drugs.Common Faults And Handling Of Air Shower
3. What is the laminar air flow unit structure?
It is mainly composed of the tank, fan, high-efficiency air filter, homogeneous membrane, lighting fixture, etc.
4. What is the laminar air flow unit working principle?
- After passing through HEPA at a certain air velocity, the air is equalized by the homogeneous membrane, so that the clean air flow is sent to the working area in an unidirectional flow.
- It is generally installed above the working area, and the air in the working area is replaced by clean air in a vertical unidirectional flow.
- Local micro positive pressure is formed in the working area, which can effectively prevent the air flow in the background area from penetrating.Differential Pressure Measurement In Cleanrooms
