Description
The ebm-papst W1G180-AB57-30 (also known as W1G180AB5730) is a high-efficiency round EC axial fan integrated with an M1G074-BF electronically commutated motor and a rugged 220 mm diameter by 70 mm deep die-cast aluminum wall ring. Powered by a flexible 24 VDC nominal supply (14 to 28 VDC range), this industrial air mover delivers up to 359.0 CFM (610 m³/h) of free-air volume at an energy-efficient 35 W power input and 3,170 RPM. Engineered for continuous S1 operation in demanding electronic environments, it pairs fiberglass-reinforced PA plastic blades with dual precision ball bearings, a galvanized rotor surface, and lateral AWG 20 lead termination. Onboard electronics provide comprehensive motor current limiting, soft starting, reverse polarity safeguarding, and active locked-rotor protection.
Key Features
- Electronically Commutated Drive: High-efficiency M1G074-BF motor delivers 359 CFM airflow with minimal 35W power draw.
- Die-Cast Aluminum Wall Ring: Black coated aluminum round housing ensures rigid mechanical alignment and vibration damping.
- Wide Voltage Tolerant: Operates reliably across 14 to 28 VDC with integrated maximum current limiting.
- Comprehensive Circuit Safety: Includes soft start function alongside built-in reverse polarity and locked-rotor protections.
- Industrial Ball Bearings: Dual precision ball bearing assembly supports maintenance-free continuous S1 duty in any mounting orientation.
