Laminar Flow Hood Working Principle
Laminar Flow Hood Working PrincipleA Laminar flow hood is a kind of air purification unit which can provide a local clean environment, and it can be flexibly installed above the process point which needs high cleanliness, clean laminar flow hood can be used individually or combined into a band clean area. It is mainly composed of a box, fan, high-efficiency air filter, damping layer, lamps and other components, and shell spraying. The product can be hung, but also ground support, a compact structure, easy to use.Laminar flow hood working principle: The clean laminar flow hood passes the air through the high-efficiency filter with a certain wind speed to form a uniform flow layer, so that the clean air is a vertical unidirectional flow, which ensures that the working area achieves the high cleanliness required by the process. Application of laminar flow hood: (1) Clean laminar flow hood has a fan inside and a fan outside two kinds, the installation mode has hanging type and floor bracket type two kinds. (2) Cleanliness: ≥ 0.5m particle size dust in the working area ≤ 3.5 / liter (FS209E100 level) (3)Noise: ≤64 Db(A) (4)Average wind speed: 0.3-0.55m/s (5)Compared with a clean room, a clean laminar flow hood has the advantages of investment saving, quick effect, low requirement for plant construction, easy installation, power saving, etc. It is currently used in precision machinery, electronics, pharmaceuticals, food, fine chemicals, and other sectors. (6) Can be specially designed according to customer requirements. Features of laminar flow hood: (1)It can be used individually or in combination. (2)The box material is made of colored steel plate, high-quality steel plate, and stainless steel plate for users to choose from. (3) Compared with civil engineering or assembly type class 100 clean room, it has less investment, quick effect, easy installation, and low operation cost. The main technical parameters of the laminar flow hood: (1) Average wind speed: 0.25-0.45m/s (adjustable) (2) Purification level: 100 level (U.S. Federal Standard 209E) (3)Power supply: 220V 50HZ (4)Noise: ≤62dB(A) The above content is mainly about the working principle of a laminar flow hood, the application of a laminar flow hood, the characteristics of a laminar flow hood, and the main technical parameters of a laminar flow hood. |
