We have further expanded our range of duct fans contributing

to more energy efficient ventilation for a better environment.

Our fans with EC-motors reduces the energy use,

thanks to their very high efficiency.

E.g. RKB EC with speed control the

energy saving is over 60% compared

with conventional AC-motors.

At max speed the energy saving is

about 40%.

The specific fan power (SFP)

reaches as low as 0,1 W(l/s).

We have improved some of our most

popular fans which are now also ava-

ilable as EC-fans.

A high quality external rotor

motor with backward curved impel-

ler guarantees energy saving and

trouble-free operation. The EC-fans

are easy to connect and their ball-

bearing motor is very easy to speed

control.

The motor is fitted with appro-

ved motor protection. The fan has

protection class IP 44.

Our swing-out design as standard

makes the fans very easy to clean.

CK EC has the same high quality,

with the same ease of installation,

and assesories as our regular CK.

There are 8 sizes of CK EC.

LPKB EC and LPKBI EC are very

low profile acoustic in-line duct fans

with circular duct connections.

LPKBI has the same benefits as

LPKB but is equipped with an in-

built silencer. section which adds a

little to its length in return for an

even lower sound level.

The fan casing is made from pop

riveted galvanised steel sheet.

Now all our roof fans are available

with EC. We have put a great effort

that the fans should be easily acces-

sible for cleaning and maintenance.

They achieve a higher airflow

compared to previous models but

with even lower sound levels.

The roof fans are manufactured

from galvanised

sheet steel

and are

polyester

plastic coated.

Östberg is one of the leading producers of

fans in the world.

In the early 1970s the founder and

owner of the company designed the first

circular and rectangular in-line radial duct

fan with external rotor motor and straight-

through airflow (180°) in the history.

We have continued to develop new

products and today we offer a wide pro-

duct range of centrifugal in-line duct

fans, roof fans, wall fans and energy reco-

very units.

Our goal is to always offer quality

products at competitive prices.
