What is the difference between a laminar flow hood and an FFU laminar flow hood?
What is the difference between a laminar flow hood and an FFU laminar flow hood?FFU laminar flow hood adopts new American technology and is suitable for obtaining a high-level clean environment in various environments. It provides high-quality clean air for clean rooms and microenvironments of different sizes and cleanliness levels. The renovation of new clean rooms and clean workshops, can improve the cleanliness level, reduce noise and vibration, and greatly reduce the cost. It is easy to install and maintain and is an ideal component for a clean environment. Wing centrifugal fan has the characteristics of energy saving, computer centralized control, stable operation, low noise, and digital speed regulation. Under the condition of initial resistance of a high-efficiency filter, it can save more than 50% of energy and have low actual operating costs. One computer can be used to centrally control the operation, speed regulation, and working status query of nearly 8,000 fans.Many people have questions about the difference between the bottom flow hood and the FFU laminar flow hood. Renhe Purification pointed out that FFU refers to a fan + filter unit (fan filter unit), while the laminar flow hood refers to a purification device that can form a vertical unidirectional flow. Structurally, the laminar flow hood is bracket-mounted, and the FFU is hoisted; the laminar flow hood can be regarded as an evolved version of the FFU, with flexible installation and more convenient filter replacement. The laminar flow hood has added a flow equalizer, which improves the uniformity of the air outlet, protects the filter to a certain extent, and has a more beautiful appearance. The return air location is also different. The FFU returns air from the ceiling, while the laminar flow hood returns air from the room. There are differences in structure and installation location, but the principles are the same, and they are all equipment for purifying air. However, the application range of the laminar flow hood is not as wide as that of the FFU. |
