Low profile duct fan LPKB Östberg
Rectangular ducted fans with a circular connection
LPKB series fans are an ideal choice in tight spaces between ceilings. These are small fans with a low profile. The total height of this type of fans is just two centimeters higher than the channel.
While maintaining great efficiency and effectiveness, as well as very good acoustic parameters, LPKB channel fans are a very practical solution when building office blocks, high-rise buildings, etc.
Thanks to the swing-out mechanism, cleaning the rotor is very simplified.
The LPK fans are equipped with a centrifugal fan with the ability to control the speed and rotor blades tilted back.
The fan housing is made of galvanized sheet. The motor with an external rotor has an IP 44 protection class.
They are also available in a version with an energy-saving EC motor, thanks to which energy costs can be reduced by up to 60%
The most important features:
- low profile – only 20 mm higher than the channel cross-section
- Swing Out solution – tilting impeller easy to keep clean
- Radial fan with speed control
- IP 44 motor protection class
- casing made of galvanized sheet
- also in the EC version
- also available with a built-in RKBI acoustic silencer
