Clean room HEPA fan filter unit (HEPA FFU) are mostly used in Class 10 and Class 100 clean rooms.The FFU has its own fan, and the air is uniform and stable. It avoids the problem of air volume balance in each air outlet of the centralized air supply system.It is especially beneficial for vertical one-way flow cleanrooms. Its Low product height helps to saves space in the air chamber when the air supply system is designed.
Clean room HEPA fan filter unit (FFU) is a modular terminal air supply device with self-powered and filtering function. The fan sucks the air from the top of the Fan filter unit and filters it through HEPA, and the filtered clean air is evenly sent out at a air flow of 0.45m/s±20% on the entire air outlet surface.

• Long operation time
SNYLI'S FFU motor has shaft current protection measures to prevent the bearing from being corroded by electromagnetic waves,thus further prolonging the working time of the FFU.
• The system is very flexible and can be adjusted at any time
Because the wall panels of the clean room are arranged with the modulus of the ceiling lattice, and due to its special node structure, the wall panels of the clean room can be adjusted at any time to change the layout of the room. At the same time, if the cleanliness of the room needs to be adjusted, it can be achieved by increasing or decreasing the number of FFUs. This is almost impossible for purification systems that usually supply air centrally.• The air is uniform and stable
The FFU has its own fan, so the air is uniform and stable. It avoids the problem of air volume balance in each air outlet of the centralized air supply system. Especially beneficial for vertical one-way flow cleanrooms.
• Significant energy saving
There are few air ducts in the FFU system. In addition to the fresh air being delivered by air ducts, the return air of FFU operates 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 FFU is generally 0.35~0.45m/s, the filter resistance is small, and the power of the FFU caseless fan is very small. The new FFU adopts a high-speed motor, and the shape of the fan impeller is also improved. to greatly improve. According to the author's estimation, the FFU system can generally save more than 30% energy than the centralized air supply purification system, so that the FFU system can save the increased initial investment (compared with the centralized air supply purification system) by saving electricity costs within two or three years.
• Save space
Since the huge return air duct is omitted, the installation space can be saved. It is very suitable for renovation projects with tight ceilings. Another benefit is that the construction period is shortened due to the relatively spacious space with few air ducts.
• Reasonable layout of air vents, lamps, smoke detectors, sprays, electrostatic neutralizers, etc.
These common devices in clean rooms all have their own installation ceiling lattice positions, which are both reasonable and beautiful. In the purification system with centralized air supply, the layout of these devices often conflicts, and the ceiling appears crowded.• Negative pressure seal
The static pressure box of the FFU air supply system is negative pressure, so even if there is leakage in the installation of the tuyere, it will leak from the clean room to the static pressure box, and will not cause pollution to the clean room.
