Description
The ebm-papst G3G140-PV17-18 (also known as G3G140PV1718) is a high-efficiency, single-inlet forward-curved EC centrifugal blower fan engineered with an integrated scroll housing and discharge mounting flange. Driven by an advanced M3G055-CF brushless electronically commutated motor, this 140 mm (5.51 in) unit operates across 230 VAC 50/60 Hz supply lines, delivering 195 CFM (330 m³/h) against high static resistance up to 550 Pa (2.21 in H₂O). Constructed with a galvanized sheet steel scroll housing, passivated rotor surface, and maintenance-free dual ball bearings, it incorporates an internal thermal overload protector (TOP) and SELV control interface for maximum thermal and operational reliability.
Key Features
- High-Efficiency EC Motor: Brushless M3G055-CF motor provides continuous variable speed regulation while drastically cutting line power consumption.
- Rugged Metal Housing: Robust galvanized sheet steel scroll housing and forward-curved impeller withstand harsh industrial duct environments.
- Flexible Speed Interface: Features 0-10 VDC and PWM control inputs alongside an integrated 10 VDC sensor power supply.
- Closed-Loop Monitoring: Integrated open-collector tachometer output provides real-time rotational feedback for mission-critical supervisory controllers.
- Comprehensive Circuit Protection: Engineered with soft start, active motor current limiting, and internally wired thermal overload protection.
- Durable Ingress Sealing: Rated IP44 with S1 continuous duty rating and rotor-side condensate discharge holes for any mounting position.

Applications
The ebm-papst G3G140-PV17-18 is deployed across forced-draft industrial HVAC systems, precision air handling units, and solid-fuel heating boiler draft blowers requiring constant static pressure delivery. It serves as a core ducted cooling component in variable frequency drive cabinets, telecom power shelters, and electronic chassis enclosures exposed to moderate filtration resistance. Its compact flanged scroll footprint also makes it ideal for automated packaging machinery drying tunnels, commercial kitchen ventilation, and laboratory fume extraction assemblies.
