Laminar flow hoods, used in cleanrooms or other controlled environments, are specialized air purification devices designed to create a localized, highly clean air environment through a high-efficiency filtration system, protecting products or operations from contamination.
Their core function is to generate unidirectional airflow (vertical or horizontal), efficiently removing airborne particles, bacteria, and pollutants, ensuring the cleanliness of the specific area meets Class 100 or even higher standards. The following is a summary of their key aspects:
Definition and Purpose: A laminar flow hood is an air purification unit that provides a localized clean environment. It is typically installed above process points or specific areas to shield against contamination risks between operators and products, ensuring product quality and safety.
It is suitable for scenarios requiring high cleanliness, such as in the pharmaceutical, electronics, or medical industries, and can be used individually or combined with multiple units to form extended clean zones.
Structure and Components: Primarily consists of a housing, fan, high-efficiency particulate air (HEPA or ULPA) filter, damping layer, lighting, and other components. The casing is often powder-coated to enhance durability; component design is compact, supporting suspended or floor-mounted installation. Fan types can be internal or external to suit different environmental requirements.
Working Principle: A fan drives air through pre-filters and HEPA/ULPA filters to remove particles, forming a stable unidirectional airflow (vertically downward or horizontally flowing). This airflow covers the work area at a uniform velocity, preventing the intrusion of external contaminants. Filtration grades can reach Class 100, meaning extremely low particle counts per cubic meter (e.g., ≤350 particles of 0.5μm size).
Main Types: Include vertical laminar flow hoods (airflow vertically downward from the top, suitable for protecting work areas) and horizontal laminar flow hoods (airflow horizontal, offering higher flexibility). Both types can be customized according to cleanliness requirements.
Application Areas: Widely used in the electronics industry (e.g., semiconductor manufacturing), photonics industry, precision instrument manufacturing, biological laboratories, pharmaceutical sterile operations, food processing, and fine chemical industries to meet the stringent air cleanliness demands of various workshops.
Compared to traditional cleanrooms, laminar flow hoods offer advantages such as lower investment, faster results, flexible installation, and energy savings, making them particularly suitable for localized clean environment retrofit projects.
