The AAF AstroFan Filter Unit (FFU) is a self-contained ceiling fan filter module, designed for use in turbulent mixing and laminar airflow cleanroom areas.

The AAF AstroFan FFU unit is a self-contained ceiling filter fan unit for use in turbulent mixing and laminar airflow cleanroom areas. The unit is designed for use with the AAF 50 and 55 mm T-Bar ceiling grid and the AstroDry HD ceiling grid, as well as other compatible grids. This unit can also be utilized in the AstroGel ND liquid seal ceiling grid. The unit is lightweight and easy to install.

The AstroFan unit is comprised of a aluminium housing with a high performance, encapsulated, direct driven backward curved fan/motor combination and a replaceable HEPA or ULPA AstroCel® II filter. For pre-filter arrangements, options include stainless steel high-pressure fans, for specific markets like the food industry.

With a clean filter at full rated airflow, this unit has a single unit SPL (sound pressure level) of 52-56 dB(a) at 1 m of the filter face. 

The AstoFan provides economical solutions for many applications. Utilizing the EC (electrically commutated) system external rotor motors greatly reduces the power consumption of the unit. Consequently, the cooling requirement will also be reduced.

Controls include the electronic commutation unit, standard single unit control, standard RFI suppression and PFC (power factor controller), and computer interface. Two wire twisted cable installations to the bus make installation easy. The main supply is the single phase 230-270V 50/60Hz. AstroCel II filter. The unit is equipped with HEPA filters in Class H14 to EN 1822, or ULPA filters Class U15, U16, or U17. All filters are factory scanned to the European Standard to ensure leak-free operation.
