Laminar flow hood is an air purification equipment that provides a local high-clean environment. It is mainly composed of a box, a fan, an initial air filter, a high-efficiency air filter, a lamp, a current-sharing membrane, and a control. The product can be hung and supported on the ground. It has a compact structure and is easy to clean and disinfect.
The clean laminar flow hood is formed by passing air through a high-efficiency filter at a certain wind speed to form a uniform flow layer, so that the clean air flows vertically in one direction, thereby ensuring the high cleanliness required in the working area.
Laminar flow hood is one of the equipment that can isolate the operator from product shielding. Its main purpose is to avoid product pollution. The air drawn from the clean room is then filtered through HEPA vertically through the operating area using fans installed in the top pressurized cabin to provide ISO 5 (level 100) unidirectional air flow to critical areas. The exhaust gas is discharged from below and returns to the clean room area. It is mainly composed of a cabinet, a fan, an efficient air filter, a damping layer, and a lamp.
Compared with clean rooms, laminar flow hoods have the advantages of less investment, quicker results, lower requirements for plant civil construction, convenient installation, and power saving. They are widely used in precision machinery, electronics, pharmaceuticals, food, fine chemicals and other fields.
Laminar flow hoods are widely used in the pharmaceutical industry. There are two types of clean laminar flow hoods: internal fan and external fan. There are two types of installation methods: hanging type and floor type. However, after the air is filtered by the fan at a certain wind pressure through high-efficiency air, the air is uniformly pressured by the homogeneous layer, and the clean air is sent into the work area in a vertical laminar flow, thereby ensuring that the work area achieves the high cleanliness required by the process. degree.
Structure Description:
The whole is made of 304 stainless steel material, and the air is sent back by using a large air volume fan or a central air conditioning system, and the temperature and humidity control is more convenient. The filter adopts the liquid tank sealing form to ensure no leakage. The laminar flow hood air flow is vertical unidirectional flow. The air outlet surface can be equipped with a uniform flow film. The wind speed is 0.36 ~ 0.54m / s. The unidirectional flow state can be verified by smoke test . The laminar flow hood is equipped with PAO dust outlet and PAO upstream sampling port, which can verify each filter on site. The laminar flow hood isolation device adopts anti-static PC board or tempered glass.
Product Advantages:
1. Pass GMP verification requirements
2. Made of SUS304 stainless steel as a whole
3. Use a large number of fans to supply air or air conditioning system
4. Adopt liquid tank seal to ensure no leakage
Control Method:
The touch screen control mode can be used to display the operation status of the laminar flow hood, such as the fan operation status, wind speed, and pressure difference. If it is connected to the particle counter, it can also display the particle online monitoring data.
