DC fans

Product line

Our centrifugal product line includes fans for

every application. Whether as free-running

impellers with a diameter between 97 mm and

225 mm or as assemblies in a ready-to-install,

compact housing with inlet nozzle with an edge

length between 51 mm and 270 mm. Of cour-

se, all models feature high-efficiency, brushless

motor technology.

Electronic protection against

reverse polarity

ebm-papst DC fans have electronically commu-

tated drives with electronic protection against

reverse polarity.The electronics are conveniently

located in the fan hub.

Product life expectancy

A distinctive feature of DC fan technology is

the convincingly high product life expectancy.

Thanks to the excellent efficiency of the brush-

less drives, the thermal load of the bearings is

reduced, thus considerably increasing the life

expectancy of the fans.

Protection class

DC fans with sleeve and ball bearings are pow-

ered by Class E insulated motors. All ebm-papst

fans conform to the requirements of Protection

Class IP 20. Fans conforming to IP 54 and spe-

cial protection classes are also available.

Voltage range

Many of our DC fans can be operated on volta-

ges that are up to 50% lower and 25% higher

than their nominal voltage (see Voltage range in

the technical tables). This enables the air per-

formance to be adapted to the cooling require-

ments and allows the noise to be reduced, even

if the fan does not have a control input.

Closed-loop speed control and monitoring

Closed-loop speed control and function monito-

ring are becoming increasingly important in

many applications. ebm-papst offers many fans

in the standard design with a control input and

open collector speed signal.

S-Force centrifugal – RadiCal

The new S-Force centrifugal fans provide peak

performance among fans of this type. With air

flow capacity at over 1500 m³/h and a pressure

build-up of up to 1000 pascals, the highest heat

flows are manageable. In addition, the models

are extremely efficient due to the multi-pole,

electronically commutated drive motors and can

be adapted individually to every application

thanks to intelligent motor features. Some

models use our new, highly efficient RadiCal

impellers.
