Your advantage

Weiss is one of the few companies

providing custom-tailored plants,

air-conditioning units, components

and process technology for clean

room applications from a single source.

Filter Fan Units that are optimal

for all clean rooms

Different clean room concepts such as

negative pressure plenum or circulating

air operation can be implemented by

FFUs from Weiss.

Besides supplying larger clean rooms,

FFUs are also suitable for implementing

clean room islands or clean worksta-

tions.

Predictable changes in use or changing

process sequences in clean rooms

require a flexible clean-air supply

system. A concept using FFUs is ideal

for this, in order to realize a clean

room concept adapted to the process

requirements by an easily altered

arrangement of FFUs, lighting and

ceiling panels.

Upgrading of clean rooms to a higher

clean room classification can also be

implemented very easily by increasing

the number of FFUs. Using the various

open-loop and closed-loop control sys-

tems employed by Weiss, appropriate

control systems, even computer-aided

systems, can be implemented for FFU

applications ranging from simple ones

to complex facilities with hundreds of

FFUs.

Filter Fan Units –

Energy-efficient and reliable

In the Weiss FFUs, motors with low

power consumption and maximum ser-

vice life are employed. Only as much

electricity is consumed for the clean air

supply as absolutely necessary, thanks

to the possibility of completely control-

ling the individual FFUs with E.C. motor

technology, via special control soft-

ware.

FFUs from Weiss are available

in a variety of versions.

High performance in relevant dimensions

Highest quality standards

Always highest standards are deman-

ded to the quality of clean rooms and

clean room components. These high

standards also involve stricter demands

for a low-turbulence, uniform inflow of

air. In Weiss FFUs, the supply air flow

required is implemented by adapting

the fan size or r.p.m.

Uniform air flows are ensured by optimum

adjustment of the motor and rotor and

the high quality of the filters. Weiss

FFUs are tested with respect to the air

flow, pressure losses and power

consumption in a special testing cham-

ber, according to DIN/EN/ISO 5801.

Here the air velocities are measured in

a specified matrix keeping a defined

distance to the filter.

Weiss Filter Fan Units are especially

quiet-running. Special methods of noise

measurement are employed.

Peaks in the frequency range are

identified, and improvements carried

out consistently.

Optimum noise levels are achieved by

a combination of ideal coordination of

the used material, the perfect layout of

motor/running wheel unit as well as

the use of sound-absorbing insulation.

In Weiss FFUs, particular attention is

also paid to reducing vibrations. Low

vibration of the motor, rotor wheel

and housing guarantee resonances

as low as possible and a high process

reliability.

ceiling fitPrecise

FFUs and ceiling installation

With Weiss FFUs it is very easy to fit

them precisely into various ceiling

constructions. The dimensions of

housings and filters are resulting from

the dimensions of the supporting

ceiling construction. The installation

and maintenance of the FFUs, and the

replacement of the filters, can be done

from the clean room or the plenum

side.

The standard type of the FFUs is de-

signed for assembly and filter exchange

from the plenum side.

FFU standard sizes

Square and rectangular ceiling geome-

tries can be implemented without diffi-

culty with the various dimensions and

process adaptations. Irregular ceiling

areas or room layouts (see illustration

below) can be covered completely very

easily with the help of the different

unit sizes.

Design variants and accessories

The Weiss FFUs are designed for

all clean room classes and applica-

tions.

Weiss FFUs can be made to a standard

design or customized to the particular

requirements. Various arrangements of

standard FFUs in the ceiling matrix in

combination with corresponding filters

allow the respective requirements for

clean air supply and process needs to

be met precisely. The possible versions

for exactly fitting installations on the

plenum or clean room side ensure per-

fect planning and installation.

Arrangement of FFUs installed on plenum side

Equipment and materials

The Weiss FFUs are supplied in the

following housing versions:

Galvanized sheet metal (standard)

Aluminum, aluminum anodiced

Powder-coated sheet metal

Stainless steel

On request, acoustic insulation linings

of glass fibers, rock wool, or foam

plastic are supplied, depending on re-

quirements. The FFUs are manufactured

to the respective fireproof classifica-

tions required.

The FFUs can be supplied with dry or

fluid seals. Water heat exchangers for

cooling or heating can be integrated

into the FFU on the suction side.

FFUs can be fitted with an electric hea-

ting system as a heater. In process-

critical steps, FFUs can be fitted with

heat-resistant HEPA filters, for example

as dryers.

In order to achieve the adapted airflow

needed in clean rooms, it makes sense

to use various air diffusers. Swirl plates

cause a high degree of mixing in the

clean room with a turbulent mixed

flow.

With perforated-plate outlets or fabric

diffusers mounted underneath, an

optimized, low-turbulence displace-

ment flow is obtained.

It is not always possible to avoid pollu-

tion of the return air. In order to pro-

tect the FFU and the high-quality HEPA

filter, preliminary filters of filter classes

G1 to G4 and F7 to F9 are available.

HEPA filters are available in classes H10

to H14 and U15 to U17, with various

filter media.

In order to meet the requirements for

perfect lighting in different clean-room

design concepts, flush-mounted, sur-

face-mounted, or teardrop luminaires

are a useful accessory. In combination

with the ceiling-matrix profile sections

and ceilings available, these allow com-

plete systems to be implemented.

FFU drive and AC technology

In the Weiss FFUs, both AC and EC mo-

tors are employed. Both types of drive

have their own specific advantages.

AC motor technology is tried-and-

tested, while the more modern EC

technology is mainly preferred for its

energy efficiency and its large control

area.

AC motor technology

In the asynchronous motor control

technology (AC) the speed is optimally

controlled via variation of the voltage

by frequency transformers. The AC

motor system cannot be disturbed by

interference. The combination of lower

capital costs with easy-to-control

motors is the preferred version for

many smaller and simpler projects.

Infinitely-variable speed control

for AC motors

The single-phase and three-phase AC

motors can be controlled by infinitely-

variable closed-loop speed controls.

The actual value is measured by air-

speed sensors. Depending on the type

of controller and expansion module,

different fittings and functions can be

selected, such as:

Power switch

Digital display or multifunction

display

Closed-loop controller or actuator

operation

Motor protection via thermal contact

or PTC thermistor

Floating status-annunciator relay

External switching over to a second

setpoint

Digital inputs and outputs

0-10 V output

RS 485 interface

Efficiency

EC motor3-phase AC, 4-pole, frequency converter3-phase AC, 4-pole, variable-voltage control 3-phase AC, 6-pole, frequency converter1-phase AC, 4-pole, variable-voltage control

EC motors are considerably more energy-efficient than AC motors

EC motor technology

EC fans have an electronically commu-

tated permanent-magnet direct-current

motor. This technology provides very

quiet running, long life, and savings in

energy. Integrated monitoring functions

protect the motor and electronic circui-

try. The stepless control of the air

quantity is done via integrated electro-

nics.

Open and closed loop controls for EC systems

Weiss Fan Controller 200 for

controlling EC motors

The Weiss Fan Controller 200 is an

independent control and monitoring

unit for activating and controlling up

to 200 FFUs with EC motor technology,

via a bus system. The fans can be con-

trolled individually or in groups. The

unit’s clear menu system, in combina-

tion with the multifunction operator’s

controls, permits rapid and easy start-

up and operation.

The additional functions, such as auto-

matic day/night switchover (externally

or internally controlled), optional closed-

loop control function for speed, three-

level user-rights hierarchy, and a non-

volatile error memory (transmittable

serially) make the Weiss Fan Controller

200 a simple and intelligent solution

for controlling and monitoring

medium-sized FFU systems with EC

technology.

Controlling with the FFU Control Center

FFU Control Center

This PC-based software system for

open-loop and closed-loop control of

the FFUs is based on MS Internet

Explorer with the operating systems

MS Windows 2000 and Windows XP.

The FFUs are controlled by the Control

Center via a very fast Ethernet connec-

tion (10/100 Mbps). The interfacing

gateways translate the protocol into

commands in a form that the control-

lers can read. The tree structure makes

it possible to address each individual

FFU in a very orderly and targeted

manner. In addition, the following set-

tings can be made for each individual

FFU, for predefined groups, or for all of

them:

Changing the speed

Start/stop

Time-controlled changes

Logfile, monthly

Forming groups of any number of

FFUs

Any number of FFUs

Operation via PC and monitor screen

Upon restarting, or after a power out-

age, the system starts up automatically

with the values set most recently.

The FFUs can be represented individually andin groups.

Different FFUs can be predefined in the layout. Operating states (on/off, speed) arerepresented in different colors.

A customized screen design can be stored in the program as the background (“wallpaper”).
