Nicotra Gebhardt has defined their core compe tences:- Aerodynamics- Acoustics- Electrical motors- Control systems
Filter Fan Units made by Nicotra Gebhardt are available- as standard or customised versions- for standard and customised ceiling grids- for different filter and grid sizes- as top load or bottom load versions- for liquid or gasket seal systems- for various air flows and pressure drops- with minimal vibration and audible noise emissions- with an external rotor motor system- speed variation via BUS or supply voltage- for various control systemsEC-version- Internet/ Intranet access for controlling, monitoring and visualising- easy to install and set up with automatically addressed motor electronics- built-in power factor controller (PFC) for reactive current compensation- integrated self diagnosis and status messages- high operational reliability as the impeller runs on latest command after power drop or loss
Nicotra Gebhardt has developed control software to monitor different ventilating systems, room configurations and airflows.
Why should FFU’s be used in cleanrooms? Benefits which count …
... Redundancy With hundreds, or thousands of individual FFU’s in a facility, the loss of one or more units does not jeopardise the inte-grity of the room.
... Flexibility As the needs or uses change in a facility, the units can be exchanged with lay-in lights or blank panels. For facilities with lower classification, upgrades can be obtained by simply adding additional FFU’s. When a computer controlled management system is installed, units or clusters of units can be remote controlled to operational needs.
... Cost effective Use motors with the lowest power consumption available. With complete controllability of each and every FFU (via control and monitoring software) use just as much of power as necessary for your process.
... Negative plenum The negative plenum design draws recirculation air from the plenum itself. If there are any leaks, they migrate to the negative plenum and NOT the cleanroom.
... Salvageability FFU’s are fully salvageable as stand alone units.

Filter Fan Units ar key elements in clean room ven-tilation systems. Nicotra Gebhardt supplies the elements for Filter Fan Units (FFU) as well as the units themselves. Starting from standard FFU de-sign, our team of experts imple-ments the specification for your special project.
Nicotra Gebhardt’s aerod ynamics research laboratories
have brought forth over 50 years of experience in leading-edge fan design and highly efficient technology.
Since the very beginning of the Nicotra Gebhardt com-pany the external rotor motor has been an essential element for driving fans. Nicotra Gebhardt has a manu-facturing facility for production of external rotor motors – the con-ventional asynchronous version and the electronically controlled brushless DC design. An expert team with special laboratories and test rigs is pushing this deve-lopment to new frontiers.

What flowrate/ air velocity do you need?
What are your noise criteria?
Sound pressure level at octave frequencies at 1.5 m distance (below filter)
Any required flow of air can be achieved by adjusting the fan size or its rotating speed. Uneven air flow distribution can be caused by a poorly designed ventilation system or by the une-ven flow of air through the filter.

Fans
Noise measurement chamber class 2 DIN 45635
Fan testing in accordance with ISO 5801 cham-ber to measure volumetric air flow, pressure dif-ference and power consumption
The demands of air flow uniformity are magnified with the increased requirements of higher room cleanliness classifi cations and more end users are specifying reduced variation of velocity profiles.
FFU longterm study
Low noise
High efficiency includes low noise levels. Special sound measuring faci-lities make it possible to detect every peak in frequency bands and to improve a spectrum by designing new noise patterns.
Air distribution measurement
Air velocity with the filter in 36 square sections of same size below the filter. No measurement point exceeded 30 %. More than 80 % have been less than ±20 % deviation.

This design feature places the motor directly in the air stream and the cooling for the motor cannot be better.
External rotor motors integrate exceptionally well into a centrifu-gal fan impeller. They don’t take up extra space because they are entirely built in the impeller without creating ma-jor disturbances to the air stream through the impeller.

What about the power supply?
Asynchronous motor
This type of motor is available as an AC motor, wound in such a way that speed control by simple voltage variation is possible. The motor is a standard and has been on the market for about 50 years.

Asynchro-nous motors
This allows the motor to operate more efficiently and therefore the motor size can be slightly smaller than that of a standard IEC motor.

installation situation
A drive unit consisting of an electronically commutated motor differs from the former DC mo-tors as there are no collector or carbon brushes.
These wearing components have been replaced in an elect-ronic commutated motor with maintenance-free electronics (control unit).
7.2 EC
voltage:VAC 1-phase
frequency:Hz
motor protection: electronicallymonitored
What about the electronics?
EC motor(Brushless DC motor)
The most advanced develop-ment is the EC motor which exploits the basic external rotor principle of a brushless DC motor.
11
This is how it works:
The EC motor has three winding circuits, which are controlled by the electronic commutation unit with a changing current impulse. The electric current results in a magnetic field which interacts with the field of the permanent magnets of the rotor. This gene-rates a torque for the motor.
EC Motors
Control unit
To create a continuous rota-ting movement of the rotor, the electric current must now be switched relative to the posi-tion of the rotating permanent magnet rotor field. The position of the permanent magnet is detected by hall effect sensors and as a result of this signal the control electronics carry out the commutation.

Network Topology:
The Nicotra Gebhardt FFU Moni-toring and Control System con-sists of a FFU control network connected to a computerised FFU Control centre. This FFU System is especially made for the high demands of clean room applications.
The FFU Control centre allows control of a large quantity of FFUs in a very flexible and future oriented way.
At the heart of the system is a control centre (server) which contains network management, process control and web server as main parts.
Several clients, running under a conventional Internet browser like Microsoft™ Internet Explo-rer™ serve as visualisation and operating console (user inter-face). An optional implementation and setup tool is available as well as an OPC access. These figures give an overview of the Nicotra Gebhardt FFU Monitoring and Control System.
The keypoint of the clean room is the FFU, which can be se-lected in different performance /efficiency / configuration and used in different places in the process or ventilating system.

Topology Overview
This Figure shows the complete FFU LAN-BUS control network topology as recommended by Nicotra Gebhardt. The field bus section uses LAN-BUS technology in ring topology for the Ethernet part and line topology for the RS485 part.
The LAN-BUS is structured with gateways with a redundant Ethernet backbone and several FFU lines. Additional I/O modules for connection to the server are also available. The FFU Server can be provided with a redundancy server in hot-standby configuration.
