The FFU COMPACT fits into 1200 mm x 600 mm ceiling grid configurations. The unit consists of the housing the integrated HEPA filter the compact fan unit with impeller, motor and inlet nozzle. The baffle plate optimizes the uniformity of airflow towards the filter. The sound absorber reduces the noise level.
The following additional components are available:
- Prefilter for coarse particle filtration
- Cooling/heating coil
- Air diffusor (perforated plate diffusor)
- Aerosol inlet connector, Aerosol measurement connector
- AMC-filter
The FIlter Fan Units generate an unidirectional airflow. A turbulant airflow is created in the room when the air diffusor is installed. If necessary, filter classes H14 to U17 can be used. The FFU-fans have sufficiant reserve capacity to overcome any additional pressure loss due to e.g. raised floors, return air ducts, prefilters or cooling/heating coils.
The FFU COMPACT AC is driven by a specially developed, single phase, external rotor AC motor with internally wired thermal contacts for overload protection.
The FFU COMPACT EC is driven by an electronically commutated, direct current, external rotor motor.
