What are the roles and advantages of laminar flow hoods in cleanrooms?A laminar flow hood is one of the devices that can shield and isolate the operator from the product and its main purpose is to avoid product contamination. It draws air from the cleanroom and passes it vertically through the operating area via a fan and HEPA filtration mounted in the top pressurization chamber, providing a unidirectional flow of ISO 5 (Class 100) air to critical areas. Exhaust air is exhausted from below and returned to the cleanroom area. Laminar flow hoods are mainly composed of a box, fans, HEPA filters, damping layers, light fixtures, and so on.The role and advantages of laminar flow hood in the cleanroom are as follows: 1, the role: The laminar flow hood can provide a clean workshop environment, and its high-efficiency air filter can filter the dust and bacteria in the air so that the air in the workshop is kept clean, to avoid product contamination. 2、Advantage: Laminar flow hood has the flexibility that can be used singly or collocated, and compared with civil engineering type and assembled building class 100 clean room, it has low investment, good effect, simple assembly, and low operation cost. The shell material of the laminar flow hood can choose color steel tile, high-quality thick steel plate, stainless steel plate, and so on. In addition, a laminar flow hood has some other advantages. For example, it can reduce the environmental pollution problems caused by people entering and leaving the clean room and achieve the cleanliness level of the clean room. At the same time, a laminar flow hood has lower noise and vibration, which can improve the cleanliness level. When installing the laminar flow hood, you need to pay attention to some details. For example, stop the machine before installation and make sure the new high-efficiency filter is not broken. When installing, lift the box when the high-efficiency filter, replace it with a new high-efficiency filter check the sealing of the sides, and then return to the original position. Ensure that the filter paper is intact when unpacking, handling, and installing for access. Overall, the laminar flow hood is a highly efficient, flexible, and practical purification equipment, suitable for a variety of process points that require high cleanliness levels. |
