🔧 Construction & Connection
The fan features a compact 40 mm square frame, with four mounting points and a 5-blade impeller, clearly visible in the photographs.
The photographed unit is supplied with wiring and connector, which is useful for installation as a replacement for existing equipment.
Delta documentation also specifies that the EFB0412VHD-F00 version uses 3 conductors, with red positive, black negative, and a third conductor dedicated to the -F00 function. For the photographed component, the actual wiring present should nevertheless be verified before connection.
⚡ Function in the Cooling System
The EFB0412VHD is designed to generate high air velocity in an extremely compact format.
With approximately 9,000 rpm, 10.10 CFM airflow, and up to 103.6 Pa static pressure, it can be used to extract or direct heat away from electronic components and equipment with high power density.
🏭 Applications
Depending on the equipment characteristics, it is suitable for:
- Inverters and converters
- Switching power supplies
- UPS systems
- Electrical panels and electronic equipment
- Power electronics
- Automation systems
- Industrial equipment
- Servers and electronic systems
-
Forced-ventilation systems in limited spaces
The 40 × 40 × 20 mm dimensions make it particularly suitable as a compact, high-speed replacement fan.
🛡️ Safety & Product Condition
The fan is used and shows normal signs of use, dust, and light superficial marks on the frame and blades, as visible in the photographs. No structural breaks are evident on the housing or impeller.
Before use, it is necessary to verify polarity, supply voltage, current consumption, and correct startup. Delta expressly specifies that connection with reversed polarity may damage the fan. During testing, suitable protection for the impeller is also recommended.
Operation is not declared tested based on the photographs alone.
