What is a Class A laminar flow hood and what are its performance characteristics?

With the continuous development of the industry, the research and application of Class A laminar flow hoods have made remarkable achievements and are widely used in fields such as medical care, biopharmaceuticals, and semiconductor manufacturing that require extremely high air quality. Class A laminar flow hood, also known as Class 100 laminar flow hood, provides laminar flow protection for the corresponding environment, similar to FFU, but does not have standard sizes and models. This product can be suspended and supported on the ground, has a compact structure, and is easy to use. Class A laminar flow hoods can be used alone or connected in various ways to form a strip-shaped clean area. Its shell is made of 304 stainless steel, and the high-efficiency filter can be composed of multiple splicing units. Laminar flow hoods are more prominent in pharmaceutical factories. The air inlet of the laminar flow hood can be at the back of the top. It complies with the new version of GMP dynamic level 100, and the wind speed in the working area reaches 0.45 m/s±20%.

The laminar flow hood cleanliness level A standard has the following points:

1. The number of suspended particles, 0.5um and 5um, must meet the standards.

2. The determination of sedimentation bacteria and planktonic bacteria must meet the standards.

3. The recommended wind speed value is 0.36~0.54m/s.

Class A laminar flow hood specifications:

1. Cleanliness: ISO level 5 (FS209E100 level).

2. Noise: ≤65dBA.

3. Face wind speed: 0.45m/s±20%.

4. Power supply: AC 220V/50HZ.

5. Pressure difference: 10-20Pa.

Class A laminar flow hood product features are diverse, and non-standard products can be customized according to customer needs. In addition to providing high local cleanliness, Class A laminar flow hoods also have the following features:

1. The installation methods are flexible and diverse. You can choose ceiling-mounted or ceiling-mounted installation, as well as various other structural designs, such as top-feed, side-feed air inlets, external air inlet circles, etc., to meet different installation methods and usage requirements.

2. Mainly used in biological and pharmaceutical industries to meet the requirements of local high-cleanliness production processes, such as large-volume infusion filling and injection production.

3. The Class A laminar flow hood is made of high-quality stainless steel, which has the advantages of never rusting, corrosion resistance, lightness, and strength. Its box design adopts the golden ratio point, and its appearance is beautiful and elegant.

4. The Class A laminar flow hood adopts an ultra-thin body design, with a thickness of only 20cm. In addition, the total thickness of domestic high-efficiency filters does not exceed 29cm, and the weight is only 24kg. This makes the Class A laminar flow hood save space and facilitates construction, installation, and daily management and maintenance.

5. The fan of the Class A laminar flow hood adopts a lifelong maintenance-free high-efficiency external rotor centrifugal fan, which has the advantages of long life, low noise, maintenance-free, and low vibration.

6. The fan system of the Class A laminar flow hood adopts an adjustable air volume design to keep the average wind speed within a certain range (0.45m/s), with low noise and uniform laminar flow.

This ends this article’s introduction to the performance characteristics of Class A laminar flow hoods. Class A laminar flow hood is a high-level air purification equipment that can produce uniform downward airflow in a specific space to achieve the purpose of clean air.
