Clean Room Hepa Fan Filter Unit

A: 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.

A: 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.

A: 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.

A: 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. 

A: 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.

A: 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.

A: The static pressure box of the Clean Room Hepa Fan Filter Unit 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.
