Description
The ebm-papst G1G140-AV17-02 (also known as G1G140AV1702) is an electronically commutated, forward-curved single-intake centrifugal blower integrated with a high-efficiency M1G055-CF brushless DC motor in a rugged die-cast aluminum scroll housing measuring 226.3 mm x 261.5 mm x 130.0 mm (8.91 in x 10.30 in x 5.12 in). Operating on a nominal 24 VDC supply across a broad 16 to 28 VDC input window, it delivers up to 235 CFM (405 m³/h) of airflow and withstands static pressures reaching 1.12 in H₂O (280 Pa) while consuming 54 W at a rated 1750 RPM. The aerodynamic assembly utilizes a galvanized sheet steel impeller supported by dual precision ball bearings for continuous S1 operation in any mounting position. Control and instrumentation are handled via a four-conductor AWG20 PVC lead wire interface featuring integrated 0–10 V / PWM speed modulation, open-collector tachometer feedback, reverse polarity protection, and soft start.
Key Features
- Electronically Commutated Drive: Integrated brushless DC motor delivers high electrical efficiency with low thermal dissipation and quiet operation.
- Die-Cast Aluminum Scroll: Robust cast housing with discharge flange provides high mechanical stiffness, structural durability, and corrosion resistance.
- Dynamic Speed Regulation: Features flexible 0-10 VDC and PWM control inputs enabling continuous demand-responsive aerodynamic curve tuning.
- Galvanized Steel Impeller: Forward-curved sheet steel wheel yields superior static pressure buildup across high air resistance systems.
- Integrated Protection Logic: Built-in circuitry delivers motor current limitation, soft starting, and active reverse polarity connection security.
