The fan company
DEVELOPMENT
C.A. Östberg in Avesta is one ofEurope´s largest manufacturer of fansfor the ventilation market. Productionstarted in 1981. New thinking is animportant ingredient in the company´sbusiness concept, which has resulted incontinuous development of products,quality, production and turnover.
As long ago as the 1970´s Hans Östberg
invented the world´s first circular inline
centrifugal duct fan with an external rotor
induction motor. Another revolutionary
invention, the rectangular duct fan, came
a few years later. Inexpensive, versatile
and easy to fit, the design revolutionised
the market in its field.
Continuous product development has
ensured that the products maintain the
highest quality on the market.
The company produces some 300 000 fans
annually and employs 140 people in a
plant covering 10000 m2.
The company is certified according to
ISO 9001 and ISO 14001.
IN THE MIND OF AN INVENTOR

RATIONALPRODUCTIONAND HIGHPROPORTIONFOR EXPORT
IN A CLASS OF THEIR OWN
The assembly line forrectangular duct fansat C.A. Östberg.
C.A. Östberg has probably Sweden´s highest proportion of production exported in the
ventilation industry. We export as much as 85 % of what we make to customers all over the
world. We believe our success, both at home and abroad, is due to the high quality and
reliability of our produts. Long series and rational production methods mean that we can
offer the market competitive prices.
Fans are supplied fully-wired with built-in capacitor and in asealed installation unit.
Ball-bearing-mounted external rotor induction motors of thehighest quality. Excellent cooling allows 0-100 % speed control.
Guide plate for higher pressure and flow.
Housings are made of strong galvanised steel.
Swing-out design.

Explanations to sound dataThe sound data have been compiled by means of sound measurement methods as follows:Pressure and flow: ISO 5801Determination of acoustic sound level in duct: ISO 5136Determination of acoustic sound level in reverberation room: ISO 3741
DesignationsLWA tot: Total A-weighted sound power level dB(A) (ref 10-12 W)=the sum of the sound power level in the octave ranges. LWA: A-weighted sound power level in octave range dB(A) (ref 10-12 W).LpA: A-weighted sound pressure level in dB(A) according to normed A-weightening correction and relating to an effective absorption area of 20 m2 with half spherical translation at a distance of 3 meters.
RK and RKC duct fans have straight throughflow with connections for either rec-tangular or cylindrical ducts. The fans have a rigid housing of galvanised steel. Theyare compact, high-capacity fans, operate quietly and can be built-in in any position.RK fans have forward or backward-curved impellers (see table). They are designedto cope with high pressures and long ducts with a minimum of noise. The motorsare maintenance-free, why the only service required is cleaning the impellers.Motors with impellers can be swung out for inspection and cleaning (swing-out).
All fans are supplied fully-wired and ready to fit in a sealed installation unit. Theyare moisture-proofed and approved for use in outdoor applications. The duct fansare not recommended for transporting grinding dust, soot, flour or similar.All fans are fitted with a built-in thermo-contact protector (see page 5).
• 11 sizes, in approx. 50 different executions.• Rectangular or circular connection.• Reliable, maintence-free ballbearing-mounted external rotor induction
motor of the very highest quality.• High pressure.• Minimum of noise.• Speed-controllable from 0-100 %.• Can be built-in in any position.• Any voltage and frequency quoted on request.• All models are fitted with an approved thermo-contact protector as
standard.• RK and RKC can be supplied with ready-fitted thermo-contact leads, e.g. for
alarm function.• All RK fans are supplied with an universal guide rail for easy fitting to rectangular
duct.
The sides can be supplied separately for connecting RK fans to RKC cylindrical ducts.
Instructions for maintenance of RK(C) The duct fan is fitted with an asynchronus motor of external rotortype with enclosed maintenance-freeballbearings. Single-phase motors are equipped with an approved thermo-contact protector with automa-tic reset. 3-phase motors are ready-wired with thermo-contact leads. These must be connected over amotorprotector, or if speed control is used, over a thermo-contact relay, fitted as standard in our 3-phasetransformers. The thermo-contact breaks the current if the temperature in the motor windings becomesexcessive. In single-phase motors the thermo-contact is reset automatically when the temperature in themotor windings falls to the permitted level. In 3-phase motors, the thermo-contact is reset as follows:Turn off the mains power. Wait until the motor has cooled. Reconnect the mains power.The fan is intended for continuous operation and can be speed-controlled by voltage variation using exter-nal equipment. It is not designed for transporting explosive gases, grinding dust, soot, flour or similar.
Electrical installation:The fan may only be installed by a qualified electrican. All RK(C) fans are supplied fully-wired and ready tofit in a sealed installation unit.1. Check that the voltage, frequency, cycles etc. of the mains supply correspond with the
specifcations on the fan´s ID plate.2. All electrical wiring and connections must be carried out in compliance with your national safety
regulations.3. The fan must be earthed.
Installation and fitting:
The fan can be installed in any position. For the maximum temperature of transported air, refer to thediagram of the fan. The fan must be fitted to a duct or fitted with a protective grille.
Care and maintenance:The only maintenance required is cleaning. We recommend inspection of the impeller every six months ifthe fan is operated continuously. Before cleaning: Disconnent from the mains and block the mains switch.Wait until the motor and impeller have stopped rotating. Care must be taken during dismantling and cleaning so as not to disturb the fan´s balance. Strong deter-gents or cleaning agents must not be used for cleaning the fan. Internal insulation may be wiped clean witha damp cloth. Sharp or rotating tools must not be used as these may damage outer surfaces.
In case of breakdown: 1. Check that mains power is reaching the fan.2. Disconnect from the mains and ensure that the impeller is not blocked.3. Check the thermo-contact according to the description above. If the thermo-contact has
activated, the cause of overheating should be determined to prevent the same fault recurring.4. Check that the capacitor is connected (single-phase, refer to the wiring diagram).5. If the fault persist, change the capacitor. 6. If these steps do not help, contact your supplier.7. Should the fan need to be returned to us, the impeller must be cleaned and motor wiring
undamaged, and a written description of the fault enclosed.
