The difference between high-efficiency air outlet and FFU and laminar flow hood
The difference between high-efficiency air outlet and FFU and laminar flow hoodA Laminar flow hood is a purification equipment that can form vertical one-way flow. FFU refers to the fan plus filter unit. Additionally, laminar flow hoods return air from the interior, while FFUs return air from the orifice plate.The purification laminar flow hood is an air purification device that is generally installed above process points with high cleanliness requirements to achieve purification effects. Plus, it can be used alone or in combination with other products, so it's great. Purification laminar flow hood, which is mainly composed of a box, a fan, a high-efficiency air filter, a damping layer, and a lamp. Purification laminar flow hood features: 1. It should be made of a high-quality aluminum-zinc plate, so it has anti-corrosion, will not rust, and is strong and durable. 2. It can save space, is very convenient to install and use, and has low power consumption and long service life. Advantages and applications of laminar flow hood: Compared with clean rooms, clean laminar flow covers have the advantages of low investment, quick results, low requirements for plant construction, easy installation, and energy saving. Widely used in precision machinery, electronics, pharmaceutical, food, fine chemicals, and other sectors. Laminar flow hood structure: There are two types of clean laminar flow covers: inside the fan and outside the fan. There are two types of installation: hanging bracket and floor bracket. A Laminar flow hood is an air purification device that can provide a local high-clean environment. It is mainly composed of a box, a fan, a primary air filter, a damping layer, lamps, and other components, and the outer shell is sprayed. This product can be hung or supported on the ground. It has a compact structure and is easy to use. Can be used alone or connected multiple times to form a strong and clean area. A clean laminar flow hood is where air passes through a high-efficiency air filter under a certain air pressure through a fan, and is pressurized by the damping layer. The clean air enters the work area in the form of vertical laminar flow, thereby ensuring that the work area reaches the high cleanliness required by the process. Precautions for using a laminar flow hood: 1. The laminar flow hood noise problem is conceivable, and even with 5000-level turbine noise during the production process, it cannot be guaranteed. 2. Laminar flow pressure balance. 3. Laminar flow hood negative pressure ventilation. This is a unique feature of the head. Because it can provide static pressure itself, it is relative to the air supply negative pressure of the static pressure box in the purification workshop. Therefore, the plenum particles will not leak the pressure in the clean area, making sealing very simple and safe. Shorten the construction period. The use of heads eliminates the production and installation of air ducts, and since air ducts are used during cleaning projects and large construction cycles, the choice becomes possible for any investor who wants to benefit as quickly as possible. 4. Flexibility of laminar flow cover. Because the head has a built-in power supply, it is not subject to geographical restrictions. In large clean workshops, partition control can be carried out as needed. As the semiconductor manufacturing process changes, the factory layout should be adjusted accordingly, and the flexibility of the head makes this adjustment easy and does not require secondary investment. 5. Laminar flow cover reduces operating costs. Although the initial investment of choosing a head is higher than that of duct ventilation, its subsequent operation highlights the characteristics of energy saving and maintains freedom. The supply of traditional central air conditioning units reduces operating costs by 40%. |
