Originally designed in Korea byKTurbo, the Aerzen Turbo Blower isnow marketed under the Aerzenname featuring this proven designfor energy efficiency.
Aerzen TB Turbo Blowersare single-stage high-speed radialturbo blowers designed to meetvarying flow and pressurerequirements in many differentprocesses. This modern frequency-controlled, gearless driven machinealong with lubricant-free aerodynamicbearings, guarantees an economical,reliable and maintenance-freecompressor operation.
Easy Installation at Minimal CostThe Aerzen TB Turbo Blower is acompact, factory tested, ready-to-install unit. It is designed to be easilymoved to its final location by forklifttruck. There is no need for anyspecial foundations.
Absolutely Oil-free OperationThe Aerzen TB Turbo Blower shaftrests on air foil bearings and thehigh frequency drive concept doesnot make use of any speedincreasing gears. There is no needfor oil lubrication, therefore no risk ofleakage or disposal problems.
High Frequency Permanent Magnet MotorThe motor is specifically designedfor high frequency applications; itsteadily maintains its high efficiency
over a wide range ofoperating speeds andloads. The motor isentirely air-cooled and capable of a wide range ofoperating speeds. The motor ismaintenance free. Its integration with theKTurbo proprietaryhigh frequencyinverter helps reduceheat generation and the system’s high speedresponse provides for awider operating range witha high rise to surge.
Frequency InverterFrequency inverter, DC choke andRFI filter are standard and integratedin the blower package. Other typesof harmonic filters can be suppliedinstead for separate installation.
Aerodynamic Bearings/Air Foil Bearings■ Air Foil Bearings are aerodynamic
bearings. At standstill, the shaftsits on a foil tightened by springs.

■ With the shaft rotation, an airwedge forms in the bearingbetween foil and shaft. This airwedge is the cushion thatmaintains the shaft in suspensionwithout any need for an externalsource of compressed air.
■ The bearings are not lubricated andthe system is absolutely oil-free.

ImpellerThe impeller is made of 17-4PHstainless steel (X5CrNiCuNb174,M.No. 1.4542) widely used in theaviation industry for very high speedcompressors. The high yield strengthgives the design engineer theflexibility needed for optimizing theimpeller for efficiency.
Minimum MaintenanceThe entire adjustment and operatingsystem is electronically controlled.Only the air filters need to beexchanged regularly.
FunctionsThe control panel ismounted in the door of theblower enclosure. It featuresa display with a water anddustproof touch-screen padinterface as well as push-buttons for start, stop andemergency shutdown.
Volume Flow ControlBlower operation is only permitted withinsafe limits (see diagram). The volume flowis infinitely adjustable within these limits.Flow and pressure capability increase anddecrease with speed. Despite fluctuatingabsolute pressure ratios (p2/p1), theoperating point can be maintained withindefined limits at all times by continuouslymonitoring intake and discharge pressures.The blower control system monitors alloperating parameters which are displayedon the HMI. The volume flow monitoring is based on a direct flow measurement atthe inlet bellmouth nozzle.
Application: Waste Water Treatment
Volume Flow Control in Conjunctionwith a Dissolved Oxygen (DO) ProbeWhere the oxygen content in a wastewateraeration basin is continuously measuredby a DO probe (4–20 mA), the controls ofthe Aerzen TB Turbo Blower compare theDO probe signal with a given set point andadjust the speed to provide the requiredair flow to meet the oxygen demand.
Aerzen means optimal,reliable, trouble-free compression.Since 1983, Aerzen USA has been supplyingand supporting Aerzen equipment in the USA,and with sister companies in Mexico andCanada expanded throughout North America.Their positive displacement machines are knownfor high reliability and efficiency and are chosenfor harsh environments, difficult applicationsand where high turndown capability is required.
Aerzen provides various types of dry singlestage, air-cooled positive displacement blowersand compressors for pressures to 50 psig andvacuum to 25.5” Hg.
With its TB Turbo Blower series, Aerzen expandsits portfolio of energy-efficient technologies forlow pressure, oil free applications.
