AstroFan FFU
Self contained Fan Filter Unit

• Available in 6 standard sizes
• Light weight bright aluminum housing
• Low sound level
• Fan motors in AC and EC technology
• Suitable tor AstroCel il filters, available in Class H14 - U17
• Available in Room Side Change execution

Application
AstroFan FFU is a selfcontained ceiling filter fan unit for use in turbulent mixing and laminar air flow cleanroom areas, The unit is designed for use with the 50 and 55 mm T-Bar ceiling grid, the AstroDry HD ceiling grid and compatible grids. When executed with a knife edge, the unit can also be utilized in the AstroGel ND liquid seal ceiling grid. The unit is light weight and easy to install.

Construction
The AstroFan unit comprises a cleaned bright aluminum housing with a high periormance, encapsulated, direct driven backward curved fan/motor combination and a replaceable HEPA or ULPA AstroCel il filler. Options include for pre-filter arrangements, high pressure fans or Stainless steel applications for specific market demands as fer example the food industry and fılling lines.

Noise level
The unit, with a clean filter at full rated air flow has a single unit SPL (Sound pressure level) of 52-56 dB(a) at 1 m of the filler face.

Motors and controls
The unit is available with traditional high efficient AC motors, operating with single phase or 3 phase motors. Controls can be either with 5 step speed controller or stepless controller. This execution provides a simple and reliable economical solution for many applications.

Utilizing EC system (electrically commutated) external rotor motors greatly reduces the power consumption of the unit, because of reduced losses. 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 interiace. Two wire twisted cable nstallation to the bus makes installation easy. Mains supply is single phase 230-270V 50/60Hz.

AstroCel II Hepa & Ulpa filters
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. Selected low pressure drop of the AstroCel II provides, in combination with the high total static pressure of the fan, a free static pressure of 70-100 Pa at full rated airflow. This results in extended filter life or it can be utilized for external use on pre-fılters or cooling coils.

Options
• Room Side Change (RSC)
• Pre-filter arrangement
• Cooling coil
• Individual ceiling frames
• High pressure fans
