What technical factors need to be considered when choosing a laminar flow hood in a pharmaceutical factory?

    A Laminar flow hood is a purification equipment used to provide a sterile or clean environment. It is commonly used in pharmaceutical factory units, biological laboratories, hospital operating rooms, and industrial manufacturing. Laminar flow hoods can protect products from contamination during the production process and ensure the normal operation of the process section. Therefore, the performance requirements of laminar flow hoods are relatively high, and many users need to spend more energy and time when choosing laminar flow hoods. What factors are related to the selection of a laminar flow hood?

    Laminar flow hood involves the safety and efficiency of the clean room working environment. Factors to consider when choosing a laminar flow hood include:

1. Type and purpose: Laminar flow hoods can be divided into two types: horizontal flow and vertical flow. Choose the appropriate type according to different needs. Horizontal flow laminar flow hoods are used for handling chemicals and sample preparation, while vertical flow laminar flow hoods are used for biological experiments and microbiology research.

2. Cleanliness level: usually from ISO 1 to ISO 9, with ISO 1 indicating the highest cleanliness, usually in line with the clean room cleanliness level ISO 5 (Category A) or higher.

3. Size and working area: According to the operating needs and equipment size, select a laminar flow hood of appropriate size to ensure that the working area can accommodate the operator and equipment.

4. Materials and corrosion resistance: Choose appropriate materials according to work requirements, such as corrosion-resistant material 304 stainless steel, to prevent chemical corrosion.

5. Air filtration system: Choose a laminar flow hood with a high-efficiency HEPA or ULPA filter to ensure clean air exhaust. Also, consider filter replacement intervals.

6. Operation and safety features: Consider the operation and safety features of laminar flow hoods, such as airflow indicators, UV lights, dust-free work surfaces, etc., to improve operator safety and operating efficiency.

7. Control system: Choose an appropriate control system according to your needs, such as touch screen control (currently more common), group control, automatic wind speed adjustment pressure difference alarm, etc.

8. Noise: Is the operating noise of the laminar flow hood appropriate? Laminar flow hoods that cannot provide a quiet operating environment do not meet the basic requirements of clean room purification projects.

9. Energy efficiency: Considering the energy consumption and airflow of the laminar flow hood, choosing an advanced-designed laminar flow hood can improve energy efficiency and reduce operating costs.

10. Maintenance and cleaning: Understand the maintenance and cleaning requirements of laminar flow hoods and choose equipment that is easy to clean and maintain.

11. Special requirements: If there are special requirements, such as explosion-proof function. It is necessary to explain the design plan to the supplier before proposing it to avoid temporary rectification of such equipment and increasing project costs.

12. Budget: The prices of laminar flow hoods of different types and configurations vary greatly.

    Through the above-mentioned technical factors of laminar flow hood, users can better choose a laminar flow hood that suits their needs. Before choosing a laminar flow hood, it is recommended to communicate and consult with the supplier to understand their technical support and after-sales service and ensure that the selected laminar flow hood complies with local safety and regulatory requirements. Taking the above factors into consideration, you can choose the laminar flow hood that best suits your experimental needs.
