_Sleeve Brushless DC Blower_ NMBTC.COM / 248.919.2250 ## **Blower** ## 05125GS-12N (51x25) ## _General Specifications_ Motor **Type:** DC Brushless Motor ## Motor Protection : Auto Restart/Polarity Protection (Motor withstands reverse connection for positive and negative leads.) ## Insulation Resistance: 10M Ω or over with a DC500V Megger ## Dielectric Withstand Voltage: AC 700V 1s or 500V 1min ## _DC Blower Benefits & Applications_ ## **DC Blower** With high static pressure, NMB centrifugal blowers are suitable for cooling electronic systems generating lots of heat and high impedance from back pressure. A DC blower contain a circular impeller within an enclosed cage, which is often referred to as a “squirrel cage”. This design allows DC Blowers to create directed airflow under high pressure conditions. A DC Blower has a more concentrated airflow in which the equipment pulls air in from the sides and forces it out at a concentrated 90º angle. ## Allowable Ambient Temperature Range: - 10°C ~ +70°C (Operating) - 40°C ~ +70°C (Storage) (non-condensing environment) ## **Benefits** - High pressure and high airflow - Cost savings with sleeve bearing, yet reliable ## _Characteristics Curves_ - Concentrated airflow to effectively cool target - Smooth PQ curve with no knee - Tacho Signal output for speed monitoring ## cs= **Applications** - Factory Automation - Humidifiers - Telecomm - OA Equipment - Network Servers - Home Appliances - Medical Devices ## _Life Expectancy L10_ 40°C 40,000 Hours ## _Specifications_ |**MODEL**|RatingVoltage|OperatingVoltage|Current|Current|Input Power|Input Power|Speed|Max.Air Flow|Max.Air Flow|Max.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
