Snyli Environmental Technology (Shandong) Co., Ltd. is one of the most reliable manufacturers and suppliers of 4x4 hepa fan filter unit in China. With abundant experience, we warmly welcome you to wholesale advanced 4x4 hepa fan filter unit from our factory. For price consultation, contact us.

4x4 Hepa Fan Filter Unit unit and 2x4 Hepa fan filter unit are the most videly used fan filter unit size.Due to the unique internal air duct design, the Fan filter unit (FFU)can ensure that the airflow speed on the air outlet surface is between 0.35 and 0.45m/s, forming a stable laminar flow, which is especially beneficial for vertical one-way flow clean rooms.

In the renovation of new clean rooms and clean workshops, it can improve the cleanliness level of some areas, greatly reduce the construction or renovation costs, and is an ideal part to provide a local high-quality clean environment. The utility model has the advantages of convenient installation and maintenance, uniform air supply, etc.

FFU fan filter unit can be connected and used in a modular way, and the system includes master controller, slave controller and FFU unit. The main control RS485 communication mode is adopted to realize the speed regulation control of 128 or 256 groups of FFUs, with the functions of patrol inspection, alarm, wind speed setting, unit address, temperature display, pressure display, etc. The system has the advantages of convenient operation, high reliability and convenient field installation. It is especially suitable for occasions with high requirements for clean environment and frequent changes in wind speed.

-- Even in case of under group control system,because each clean workshop has its own air supply part, even if one of them fails, it will not affect the operation of the entire system. Only need to repair the faulty module. For manufacturers, maintenance is quick and does not affect the normal operation of the system, and its reliability and stability are very high.

-- Due to the unique structure and sealing method of the FFU, the filter in the FFU is in close contact with the fan casing and will not leak, which can achieve a good sealing effect. The service life will not be damaged, and the extension of the service life saves the maintenance cost of the system.

-- There are few air ducts in the FFU system. In addition to the fresh air being delivered by air ducts, a large amount of return air is operated in a small cycle, thus greatly reducing the resistance consumption of the air ducts. At the same time, since the surface wind speed of the 4x4 Hepa Fan Filter Unit is generally 0.35~0.45m/s, the filter resistance is small, and the power of the FFU caseless fan is very small.
