<strong>DC</strong> <strong>fans</strong>Technical in<strong>for</strong>mationRange of <strong>fans</strong>ebm-papst offers you the widest full productline of <strong>DC</strong> axial <strong>and</strong> diagonal <strong>fans</strong>: From 25 mmto 280 mm in size. Every single type of fan canbe optimally integrated in the respective deviceconcept. The highly economical brushless motortechnology of these <strong>fans</strong> provides a uniquevariety of intelligent innovations that can berealised today at prices that would have beenunthinkable just a few years ago.Electronic protection againstreverse polarityebm-papst <strong>DC</strong> <strong>fans</strong> have electronically commutateddrives with electronic protection againstreverse polarity.The electronics are convenientlylocated in the fan hub.Product life expectancyA distinctive feature of <strong>DC</strong> fan technology isthe convincingly high product life expectancy.Thanks to the excellent efficiency of the brushlessdrives, the thermal load of the bear ings isreduced, thus con siderably increasing the lifeexpectancy of the <strong>fans</strong>.Protection class<strong>DC</strong> <strong>fans</strong> with sleeve <strong>and</strong> ball bearings are poweredby Class E insulated motors. All ebm-papst<strong>fans</strong> con<strong>for</strong>m to the requirements of protectionclass IP 20. Fans con<strong>for</strong>ming to IP 54 <strong>and</strong> specialprotection classes are also avail able.Voltage rangeMany of our <strong>DC</strong> <strong>fans</strong> can be operated on voltagesthat are up to 50% lower <strong>and</strong> 25% higherthan their nominal voltage (see Voltage range inthe technical tables). This enables the air per<strong>for</strong>manceto be adapted to the cooling requirements<strong>and</strong> allows the noise to be reduced, evenif the fan does not have a control input.Closed-loop speed control <strong>and</strong> monitoringClosed-loop speed control <strong>and</strong> function monitoringare becoming increasingly important inmany applications. ebm-papst offers many <strong>fans</strong>in the st<strong>and</strong>ard design with a control input <strong>and</strong>open collector speed signal.S-ForceThe new S-Force <strong>fans</strong> with their extremely highblower capacity of up to 950 m 3 /h <strong>and</strong> pressurebuild-up of up to 1200 pascals are capableof dealing with the extreme heat load. If needed,these <strong>fans</strong> can produce up to 100% moreoutput under full load <strong>and</strong> they work with amuch broader delivery b<strong>and</strong>width than currentmodels. This makes them ideal <strong>for</strong> equipment<strong>and</strong> systems with a high density of components.Thanks to intelligent motor features, theycan be individually adapted <strong>for</strong> any application.S-Force <strong>fans</strong> are available in 5 st<strong>and</strong>ard dimensions.18
