Description
The Delta AFL22AUHW-P0 (also known as AFL22AUHWP0) is a high-efficiency round tubeaxial Energy Saving Technology (EST) brushless EC cooling fan measuring Ø222 mm × 85.70 mm (Ø8.74 in × 3.37 in). Engineered for universal industrial applications, this unit operates across 115 / 230 VAC dual input voltages with selectable 1800 / 2500 RPM speeds, delivering up to 323.9 CFM (550.3 m³/h) of airflow against a maximum back pressure of 0.630 in H₂O (156.9 Pa) at just 17.0 W power consumption. Mechanical construction integrates a robust housing, dual precision ball bearings, and IP56 ingress protection for reliable performance in hostile, moisture-prone settings. Critical reliability features include integrated Thermal Overload Protection (TOP), locked-rotor auto-restart protection, 3-wire lead termination, and ATEX explosion-proof certification.
Key Features
- Dual-Voltage EC Drive: Operates seamlessly across standard 115 VAC and 230 VAC mains with minimal input power consumption.
- Dual-Speed Selection: Offers switchable 1800 RPM and 2500 RPM operating modes to balance acoustic emissions against airflow demand.
- Harsh-Environment Sealing: Features rugged IP56 ingress protection guarding internal motor electronics against heavy dust ingress and high-pressure water jets.
- Comprehensive Motor Protection: Integrates automatic thermal overload protection alongside locked-rotor protection to safeguard against electrical and thermal faults.
- Hazardous Area Certified: Carries ATEX compliance alongside CE, cURus, and TUV approvals for deployment in volatile commercial refrigeration systems.
