for the use in turbulent cleanroom areas with low requirements regarding noise level. Depending on the configuration of the filter coverage and of the filter classes, cleanroom classes of ISO 5.0 to ISO 8.0 according DIN EN ISO 14644-1 can be reached.
The FFU LIGHT is available with a alternating current motor or a EC-Motor.
The product FFU LIGHT EC is protected by patent.

The unit consists essentially of the housing, the HEPA filter cell and the compact fan unit with impeller and motor with inlet nozzle.
The following additional accessories are available:
If necessary filter cell classes H13 to U17 can be used.
The FFU fans have sufficient reserve capacity to overcome any additional pressure loss due to e.g. raised floor, return air ducts, prefilter or cooling/heating coils.
The FFU LIGHT AC is driven by a special developed single phase external rotor AC motor with internally wired thermal contacts for overload protection.
The FFU LIGHT EC is driven by an electronically commutated external rotor motor.
