Cleanroom Fan Filter Unit

The Cleanroom Fan Filter Unit, also known as an FFU, combines a fan, high-efficiency filter and control components in one modular clean-air device. Air is drawn from the upper section or return-air area, passes through the internal HEPA or ULPA filtration stage and is then supplied continuously to the clean space below.

Rated airflow ranges from 770 to 2,300 m³/h. The outlet face velocity can be configured from 0.30 to 0.50 m/s. Available filtration grades include H13, H14 and ULPA, while the listed typical initial static pressure is 80–120 Pa.

An EC high-efficiency fan can be used, and airflow can be adjusted through speed control according to cleanroom requirements.

Unlike a passive filter that relies entirely on a centralized air-handling system, each FFU actively provides filtered airflow through its own fan.

Multiple units can therefore be arranged according to cleanroom area and air-supply requirements. If the production area or process layout changes, the number of units or individual airflow settings can be adjusted to change the clean-air supply capacity.

The supplied information gives actual FFU sizes ranging approximately from 1132 × 532 mm to 1132 × 832 mm, with corresponding airflow of around 770–1,730 m³/h. These units can operate at approximately 0.3 or 0.5 m/s outlet velocity depending on the configuration.

The Cleanroom Fan Filter Unit can be used in electronics cleanrooms, semiconductor production areas, pharmaceutical zones, laboratories, clean booths and modular clean spaces.

Jiangsu Renhe develops products in air filtration, purification systems and energy-saving intelligent equipment. Its technical capabilities cover product design, filtration materials and equipment technology.

For project selection, FFU configuration can be discussed according to clean-area dimensions, target filtration grade, required outlet velocity and control method. Non-standard equipment can be produced through OEM/ODM or according to technical drawings and prototypes.

Before production, buyers can confirm module dimensions, filter grade, control requirements and available installation space. This is particularly useful when a Cleanroom Fan Filter Unit needs to fit an existing ceiling grid or a defined process area rather than using a standard module size.

During production, equipment photos or videos can be shared with the buyer. Finished units receive a 100% inspection before packing, and third-party inspection is supported.

International transportation can use cartons with three-plywood pallets or wooden cases according to FFU dimensions. Packaging is intended to protect the housing, fan, filter and control components during handling.

The supplied information also supports sample and custom development discussions, with a listed customized sample-development period of 7 days.
