FFU is abbreviation of Fan Filter Unit. It is a modular terminal air supply device with its own power and filtering effect. Its main function is to inhale the air from the top of the FFU by the fan and filter it by HEPA, and the filtered clean air is evenly sent out at the air velocity of 0.45m/s+20% on the entire air outlet surface to meet the cleanliness requirements of the clean environment. It is mainly installed on ceiling keels and equipment machines in clean areas and working areas. It is widely used in semiconductors, optical electronics, precision instruments, biopharmaceuticals, aerospace, and automobiles, hospitals, food, spraying, printing and other fields.

The introduction of fan filter unit
The fan filter unit is a self-powered terminal air supply device with filtering function, the fan sucks in air from the top and filters it through the HEPA filter in order to create clean air and evenly send out from the air outlet, it provides stable and strict air environment control for cleanrooms. The fan filter unit can be connected in modules to meet the needs of different enterprises and scientific research for different clean environments.
According to different usage requirements, the FFU control method could be selectable from single control, electric box small group control, touch screen small group control, computer group control etc

1. What is an air shower?
Air showers are antechambers that help decontaminate personnel prior to their entering a critical environment. Decontamination is completed through a cycle where air is blown through nozzles that are evenly distributed throughout the enclosure walls. This air is recirculated through
HEPA filters and clears dust and dirt particles off the bodies of personnel.
2. What is the air flow velocity inside the air shower?
When the shower cycle commences, pressurized air streams from adjustable nozzles at a velocity of
3. How often do the HEPA filters need to be replaced?
The frequency at which the HEPA filters need to be replaced depends on each application. Test when the filters need to be replaced
if air flow at the air nozzles reduces significantly.
