Description
The Sunon A2259-MBT.TC.N.GN (also known as A2259MBTTCNGN) is an industrial-grade AC round tubeaxial cooling fan measuring Ø254 x 89 mm (10.0 x 3.5 in) engineered for high-volume thermal management across electrical enclosures and heavy machinery. Powered by a dependable 220–240 VAC 50/60 Hz capacitor-run Alveolate motor, it delivers an airflow of 425 CFM (722.1 m³/h) at 1400 RPM on 50 Hz and 500 CFM (849.5 m³/h) at 1600 RPM on 60 Hz while drawing just 23 W to 30 W. The mechanical structure features a rugged die-cast aluminum frame paired with a lightweight, flame-retardant UL 94V-0 polycarbonate impeller and dual precision ball bearings rated for continuous operation across -10°C to +70°C. Comprehensive operational safety is assured through integrated thermal cutout protection, locked-rotor automatic restart capability, and quick-connect spade terminals.
Key Features
- Reliable Alveolate Motor: Patented thermal-dissipation motor design paired with an integrated run capacitor ensures stable continuous-duty efficiency.
- Robust Die-Cast Housing: Heavy-duty round aluminum alloy frame withstands harsh industrial environments while suppressing resonance and mechanical vibration.
- Dual Precision Ball Bearings: Engineered for extended service life and smooth rotation in any mounting orientation up to 70°C.
- Integral Thermal Cutout: Built-in thermal protection and automatic restart prevent stator coil overheating during locked-rotor or overload conditions.
- High Aerodynamic Delivery: Optimized 7-blade PC impeller yields up to 500 CFM airflow with 0.31 in H₂O static pressure.
