The Delefun DFB5015 12V DC blower fan is designed for compact installations that need concentrated airflow and pressure-focused cooling. With PBT frame/impeller materials and Class A insulation, it supports stable operation across -10°C to 70°C for 2026+ cooling projects.
Overview: 50x50x15mm 12V DC blower fan for 3D printer cooling
In industry naming, “5015” commonly refers to the form factor 50×50×15mm. Some listings shorten this as “φ50×15”, but the standard format is 50×50×15mm with tolerance ±0.5mm. This makes it a practical 50x50x15mm 12V DC blower fan for 3D printer cooling, humidifiers, and small electronics cooling needs.
If you’re choosing between airflow and static pressure, see our internal guide: Cooling Fan Selection Guide.
