What Is a Fan Filter Unit?
A fan filter unit is a device designed to supply purified air.
Operation starts with the fan pulling air into the unit, which then passes through a HEPA filter, trapping over 99.97% of microscopic particles, and finally releases the purified air. These units are essential in environments requiring high levels of cleanliness such as cleanrooms, laboratories, medical facilities, and food processing plants.
The unit comprises a fan, pre-filter, HEPA filter, and diffuser, working together to ensure optimal air purity. Its advantages include superior air cleanliness, straightforward installation and maintenance, efficient use of space, and economical operation. When implementing these units, regular maintenance of filters, airflow velocity adjustments, and thoughtful placement are crucial for sustained performance and effectiveness.
