Description
The Sunon A2175-HBT.TC.GN (also known as A2175HBTTCGN) is a heavy-duty industrial AC axial cooling fan engineered with an oval 171.5 × 151.5 × 51.0 mm (6.75 × 5.96 × 2.01 in) die-cast aluminum housing and a flame-retardant UL 94V-0 polycarbonate impeller. Operating across a nominal 220–240 VAC 50/60 Hz supply, the unit delivers high-velocity airflow rates of 203 CFM (344.9 m³/h) at 2800 RPM on 50 Hz and 239 CFM (406.1 m³/h) at 3200 RPM on 60 Hz against static pressures reaching 0.69 in H₂O (171.7 Pa). Electrically driven by Sunon’s proprietary Alveolate motor topology with an integrated run capacitor and internal thermal cutout, this precision ball-bearing assembly connects via dual 7.5 mm faston terminals to ensure stable thermal dissipation across high-impedance industrial electronics.
Key Features
- Alveolate Motor Architecture: Proprietary internal motor core with integrated capacitor optimizes magnetic flux and electrical efficiency.
- Dual-Frequency Airflow: Delivers high delivery rates of 203 CFM at 50 Hz and 239 CFM at 60 Hz.
- Thermal Cutout Protection: Integrated internal thermal protector safeguards motor windings against overheating during sustained high-load conditions.
- Die-Cast Aluminum Frame: Rigid metal alloy housing prevents structural deformation in demanding elevated-temperature operating environments.
- Precision Ball Bearings: Heavy-duty dual ball bearing system ensures long maintenance-free service life across any mounting orientation.
