how does fan filter unit work?
How does fan filter unit work？The working principle is to use the FFU fan filter unit's internal fan (motor + impeller) to suck in air (wind), and the absorbed air (wind) passes through the HEPA (high-efficiency air filter) or ULPA (ultra-high-efficiency filter) filter screen below the FFU, filtering out large particles and dust particles in the air, and finally uniformly delivering the clean air at a wind speed of 0.45m/s ±10% to the clean room.

Key features of a Detachable Fan Filter Unit include：
1、Ultra-thin fan filter unit, with a large intake area, provides higher and constant purification efficiency. The unit is equipped with an outer cover to effectively protect the air intake. It features a pure aluminum frame filter, which has better quality compared to regular filters. It is not easily deformed and has a relatively long lifespan. The detachable fan filter unit uses imported motors, allowing for continuous 24-hour operation without generating heat, significantly improving work efficiency.
2、Detachable Design: The FFU is designed to be easily attached or detached from the ceiling or wall of the cleanroom. This allows for convenient installation, replacement, or reconfiguration of FFUs as per the specific requirements of the cleanroom layout.
