DC axial fans 2011 [PDF] - ebm-papst

DC fansTechnical informationRange of fansebm-papst offers you the widest full productline of DC axial and diagonal fans: 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 fans 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 DC fans have electronically commutateddrives with electronic protection againstreverse polarity.The electronics are convenientlylocated in the fan hub.Product life expectancyA distinctive feature of DC 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 fans.Protection classDC fans with sleeve and ball bearings are poweredby Class E insulated motors. All ebm-papstfans conform to the requirements of protectionclass IP 20. Fans conforming to IP 54 and specialprotection classes are also avail able.Voltage rangeMany of our DC fans can be operated on voltagesthat are up to 50% lower and 25% higherthan their nominal voltage (see Voltage range inthe technical tables). This enables the air performanceto be adapted to the cooling requirementsand allows the noise to be reduced, evenif the fan does not have a control input.Closed-loop speed control and monitoringClosed-loop speed control and function monitoringare becoming increasingly important inmany applications. ebm-papst offers many fansin the standard design with a control input andopen collector speed signal.S-ForceThe new S-Force fans with their extremely highblower capacity of up to 950 m 3 /h and pressurebuild-up of up to 1200 pascals are capableof dealing with the extreme heat load. If needed,these fans can produce up to 100% moreoutput under full load and they work with amuch broader delivery bandwidth than currentmodels. This makes them ideal for equipmentand systems with a high density of components.Thanks to intelligent motor features, theycan be individually adapted for any application.S-Force fans are available in 5 standard dimensions.18
