� SimilaritiesSilentBox® SB ECand SlimVent SVS EC

� InstallationInstallation in any position with-out restriction – horizontally, ver-tically or pitched – suitable forintake or extract. Mountingbracket included in delivery.

� MotorEnergy saving, speed control-lable EC-external rotor motorswith highest efficiency, protectionto IP 44 (SB EC 125 A IP 54).With ball bearings, maintenance-free and interference-free.Dynamically balanced for lownoise operation.

� Speed controlStepless speed control with po-tentiometer or stepless speedcontrol with universal controlsystem (see table). Duties atdifferent speeds are exemplarilygiven in the performance curve.

� Motor protectionIntegrated electronic tempera-ture monitoring for EC-motorand electronics.

� Sound levelsSee page 351.

� Specification SilentBox® EC� CasingLike an internal attenuator.Acoustically lined with abrasiveresistant 50 mm thick mineralfibreboard. Four quick releaseclamps permit easy access tothe impeller set. Motor-impellerunit can be pulled out, the pull-out range must be considered.Spigots on intake and exhausttwin-seal rubber gaskets fitstandard ducts. All parts manu-factured from galvanised sheetsteel.

� ImpellerWith backward curved impeller.Inflow via inlet cone.SB EC 125 A forward curved

impeller in aerodynamically opti-mised volute casing, galvanisedsheet steel.

� Electrical connectionTerminal box (IP 54) mounted onrunning cable.

� Protection classWith a connected pipe systemIP 44 (SB EC 125 A IP 54).

� Specification SlimVent SVS EC� CasingExtremely flat casing in longerdesign with more than 50 mmthick sound-absorbing mineralwool lining and glass fibre sur-face. The acoustic box which isplaced in front of the fan reducesthe sound level for the intakesignificantly. The sound level ofthe case breakout is reduced toa smaller extent (see sound lev-els in the tables above the per-formance curves).

� The swing out motor and im-peller unit permits maintenance

and cleaning without disassem-bly of system components. Theswing-out range of the motor-impeller unit must be consid-ered.

� ImpellerEnergy-saving centrifugal im-peller with backward curvedblades from high quality poly-mer.

Rectangular centrifugal fansProduct specific information

For complete information seethe “general technical infor-mation” and descriptions onthe product pages.

� Position, installation anddrainage holesModels can be installed in anyposition, however types KRmust be installed with the in-spection flap facing downwardsor to the side. The swing-outareas need to be cleared andaccessed easily for service andmaintenance.If condensation occurs (e.g.ntermittent operation, high hu-midity or varying temperatures)the fan must be installed in away that the condensation candrain off unhindered.Additional holes may have to bedrilled into the casing at the ap-propriate positions. Alternatively,the duct system may have to beinsulated to avoid condensation.

� Noise/vibration transmissionTo be prevented from ductingand building. Therefore, the fanshould be secured with soundinsulation and connected flexiblyto the ducting.For this, see VS accessories.

� Explosion proof modelsWith regards to operating condi-tions and norms please refer tochapter “Information for planning– explosion proof”. The ex-pro-tected types correspond to unitgroup II, category 2G for opera-tion in zone 1 and 2 pursuant toDirective 2014/34/EU (ATEX).The motors of the KVD Ex rangeare equipped with positive tem-perature coefficient (PTC) ther-mistors (to monitor the tempera-ture of windings) as standard.They are prewired to the termi-nal board and must be connect-ed to the motor protection trip-ping unit MSA.This makes the KVD Ex fanssuitable for speed control thatcan be carried out via TSD orTSSD transformer controllers.The minimum voltage should notdrop below 100 V.Electronic speed control or reg-ulation by means of a frequencyinverter are not permitted.

� Motor - ImpellerAll AC types incorporate a motorwith external rotor motor pro-tected to IP 44 or IP 54 withinthe air flow. They conform toDIN EN 60034 / VDE 0530 andDIN EN 60335-1 / VDE 0700-1with an insulation class F, plusmoisture protection.The EC types are equipped withenergy-saving, speed-control-lable EC external rotor motorsprotected to IP 44 or IP 54 forthe lowest operating costs.

All motors are maintenance free,interference-free, speed control-lable and suitable for continuousoperation.The ball bearings are greasedfor life.The centrifugal impellers arepressed onto the rotating part ofthe motor body and dynamicallybalanced to DIN ISO 1940 T.1 –class 6.3 as one unit.

� Speed controlAll InlineVent® AC rectangularfans are speed controllable viavoltage reduction of 0 – 100 %.Thereby the operating level canbe adapted to the required airflow volume. Our speed con-trollers are suitable to controlvarious fans (one or more) up totheir maximum nominal output.When selecting a controller notshown on the chart, allow for a10 % safety margin.It is possible to control 3 ph.-fansthrough frequency inverter by on-site installation of sine filters be-tween inverter and motor.All EC types are steplessly con-trollable via speed-potentiome-ter. Regulation is also possiblevia three-step switch or step-lessly via universal control sys-tem or electronic differentialpressure/temperature controller.For example, the performancelevels are shown on the charac-teristic curve.

� Air flow directionThe air flow direction of centrifu-gal fans is fixed and cannot bereversed; but it can be specifiedin all units through the installa-tion method. The rotational di-rection and the direction of airflow are marked with arrows onthe units and must be checkedwhen installing.

� Incorrect direction of rotationIf the fan is operated in the in-correct direction of rotation theAC motor will be overloadedand the thermal contacts willtrip. Typical indication of this is avirtually low fan efficiency com-bined with high noise levels andvibration.

� Air flow temperatureAll models are applicable in therange of – 40 °C to at least+ 60 °C, types KV Ex from– 20 °C to +40 °C.The upper temp. threshold valuevaries between the models andcan be found at the relatedcharts on the individual productpage.

� KVCentrifugal rectangular fans withforward curved impeller paddlesand swing-out motor impellerunit. Low-noise centrifugal im-pellers in volute casing for highpressure levels.

V.

= 920 – 8500 m3/h.Compact and flat design for ver-satile usage in exhaust and freshair systems in commercial andindustrial applications.

Counterflange – Flexible connectorsVolume control dampers – Servo motor

� Counterflange GFDesigned for connecting rectan-gular fans and accessories toducting where the flange framesare made of galvanised sheetsteel.

� Connectors VSFlexible ducting connector withflange frames on both ends,made of galvanised sheet steel,with sealing lip all around; leakproof to VDI 3803, temperatureresistance from –10 °C to+80 °C. The elastic sleeve inthe middle section is made ofplastic fibre bonded material.Designed to fit into rectangularfans.In order to prevent the vibrationtransmission and compensatesmall misalignments on site, theflexible connectors are fitted be-tween the ducting and fan on in-take and exhaust side.For explosion proof rectangularfans use VS Ex (explosion-proof)types.

� Volume control dampers JVKFlanged casing on both sides,made of galvanised sheet steel,designed to fit into rectangularfans. The blades are hollow andtheir shafts run embedded inpolymer guides. The externalcontrol lever adjusts all bladesequally.The control mechanism is alsooutside the airstream and se-cured against operational inter-ruptions therefore unaffected byairborne contamination.The blades create an additionalpressure loss (shown in the ad-jacent diagram) which must beconsidered when designing.

� AccessoriesServo motorSTM 10 230 V Ref. no. 8791Electric drive for opening andclosing of volume control dampersJVK. Installation in any position byusing fixing clamp (for Ø 8–26 or

8 – 26 mm) and fixing with theattached anti-rotation lockingbracket.Adjustment of shutter position byusing the gear unlock button.Output signal available to indicate“open” or “close”. Visible indicationof shutter position (0 – 90°).
