What is the difference between the working principles of air supply vents and FFU laminar flow hoods
What is the difference between the working principles of air supply vents and FFU laminar flow hoods?The air supply vent and FFU laminar flow hood should be understood in the purification industry. It is a commonly used clean room equipment. As a rising star, it will always be better than the laminar flow hood. Then, the difference between them is What? There are two types of laminar flow hoods: internal fan and external fan. The installation methods include hanging type and floor-standing bracket type. The laminar flow hood can be flexibly hoisted above the process points that require high cleanliness to meet local cleanliness requirements.Introduction to the use and working principle of FFU: The FFU fan filter unit can be connected and used in a modular manner. FFU is widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms, and local level 100 applications. FFU is equipped with primary and secondary filters. The fan sucks the air from the top of the FFU and filters it through the primary and secondary filters. The filtered clean air is sent out at a uniform wind speed of 0.45M/S±20% on the entire air outlet surface. Suitable for obtaining other clean environments in various environments. It provides high-quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. In the renovation and renovation of new clean rooms and clean factory buildings, the cleanliness level can be improved, noise and vibration can be reduced, and the cost can be greatly reduced. It is easy to install and maintain, making it an ideal component for clean environments. The air supply port adopts the latest Japanese design, which makes the airflow distribution more reasonable and the box structure simpler and more reliable. It is a terminal filter device used to renovate and build new 1000-300000 class clean rooms and is a key equipment to meet the purification requirements. Both air supply vents and FFU products are necessary equipment for clean rooms. The difference between the two is whether there is a fan, different costs, and different production structures. Let us mainly introduce the working principle of the air supply vent FFU. What is the difference? Introduction and working principle of the air supply outlet: The air supply outlet is composed of four sets of air outlet static pressure box, air outlet diffuser plate, filter, and flange. The interface between the air supply outlet and the air duct of the air supply unit can be connected sideways or at the top, which is mainly convenient for the construction site. The surface of the air supply box is made of cold-rolled steel plate, multi-layer pickled, and electrostatically sprayed. The air outlets have good airflow to ensure the purification effect. Commonly used plates for making air supply outlets include cold-rolled steel plates (A3 plates) and stainless steel plates (SUS201, SUS304, SUS316, etc.). The role of the air supply outlet in clean room purification engineering: A. The air supply outlet is a non-powered air supply device and is one of the filter purification equipment devices of clean room purification engineering. B. The air supply outlet and air conditioning purification air supply system are key equipment used to transform and build terminal air filtration equipment for clean rooms of class 1,000, class 10,000, class 100,000, and all levels to meet purification requirements. C. Air outlet purification equipment can be widely used in purification air conditioning systems in medicine, health, electronics, chemical industry, and other industries. FFU introduction and working principle: The fan filter unit is a self-powered air supply filter unit, the full English name is (Fan Filter Unit), a modular terminal air supply device with filtering effect. The fan filter unit inhales air from the top and passes it through the FFU filter. The filtered clean air is evenly sent out on the entire air outlet surface at a network speed of about 0.45M/S±20%. The FFU fan filter unit can be connected in a modular manner. The FFU fan filter unit is widely used in clean rooms, dust-free operating tables, dust-free production lines, assembled clean rooms, and local level 100 applications. The FFU fan filter unit can be used to make a simple clean workbench, clean shed, clean transfer cabinet clean storage closet, etc. |
