Description
The Delta AFB0412VHA-A (also known as AFB0412VHAA) is an ultra-compact 40 x 40 x 10 mm (1.57 x 1.57 x 0.39 in) brushless DC axial cooling fan engineered for high-density thermal management. Powered by an integrated single-phase, 4-pole motor operating at 12 VDC, it delivers an airflow rating of 9.25 CFM (15.72 m³/h) and static pressure up to 0.242 in H₂O (60.4 Pa) at 8000 RPM. Constructed with flame-retardant UL 94V-0 thermoplastic housing and impeller, the assembly utilizes dual precision ball bearings for continuous industrial duty. Electrical connection is established via 309 mm UL 1007 AWG #28 lead wires, complemented by built-in locked-rotor electronic shutdown and reverse polarity protection.
Key Features
- Precision Dual Ball Bearings: Heavy-duty dual ball bearing system ensures up to 70,000 hours continuous service life at 40°C.
- High-Density Aerodynamic Profile: Compact 10mm ultra-thin frame generates 9.25 CFM airflow and 0.242 in H₂O static pressure.
- Comprehensive Electrical Safety: Integrated polarity protection and automated locked-rotor shutdown prevent motor burn-out during stalled conditions.
- Flame-Retardant Construction: Glass-fiber reinforced UL 94V-0 plastic frame and impeller satisfy rigorous commercial safety mandates.
- Pre-Terminated Industrial Leads: Factory-stripped 309mm AWG #28 lead wires enable rapid integration across tight electronic assemblies.
