English is a Fan Filter Unit, and the Chinese Professional terms are fan filter units (units).
FFU can be modularly connected, using FFU widely used in clean room, clean workbench, clean production line, assembled clean room and local levels.
FFU is generally provided with an initial and efficient two-level filter. The fan is inhaled from the top of the FFU and filtered through the initial, high-efficiency filter, and filtered clean air is delivered at a wind speed of 0.45 m / s ± 20% throughout the wind. Suitable for obtaining a high level of clean environment in a variety of environments. It provides high quality clean air for different sizes and clean rooms of different sizes, different cleanliness levels.
In the new clean room, clean factory-type renovation, the cleanliness level can be improved, reducing noise and vibration, can also greatly reduce cost, easy to install and maintain, is an ideal component of clean environment.
Large area uses to provide clean environments, mostly used for Class A or higher levels, generally requires the floor form as elevated floor, have a backwind, and the level is also guaranteed to ensure a low level of cleanliness, high cost.
The lamination is a air purification apparatus that provides local high clean environment. It is mainly composed of a cabinet, a fan, an initial air filter, a damping layer, a lamp, and the like, and the outer casing is sprayed. The product can be suspended, and it can be supported, and the structure is compact and easy to use. You can use a single use or multiple connections to form a strip-shaped clean area.
The lamination is a spherical flow layer to form a unidirectional stream of the air in a certain fly gas, so that the clean air is vertically unidirected, thereby ensuring the cleanliness of the work area to achieve the process requirements.
Clean layer flow cover has two types of fan in the wind turbine, and the installation method has a suspension and landing stent type two labs, which is a damping layer by the damper layer after a certain wind pressure by a high-efficiency air filter. It is clean air to be a vertical layer flow airflow to the work area, thereby ensuring the high cleanness required for the work area to achieve the process.
Compared with the clean room, the flow cover has the advantages of investment in the province, the effectiveness of the plant, the advantages of low installation, convenient installation, power-saving power, etc., are currently used in precision machinery, electronics, pharmaceutical, food, fine chemical and other departments.
The lamination structure is complicated than the FFU. It is a relatively low environmental condition for local purification equipment. It is used to provide local relatively high cleanliness, suitable for renovation projects, and overall requirements are not very high, just meet the local requirements. It can be used alone or in parallel.
