New Energy Power parts Electric fan VA109-BBL335PN-109ASH

Equipped with a 109mm diameter fan blade (adopting aerodynamic curved design) and a high-torque brushless motor, the fan delivers a maximum airflow of 350-400 CFM (cubic feet per minute) and a static pressure of 25-30 Pa—effectively reducing the temperature of NEV components by 15-20°C under full load. The blade’s optimized pitch (15-18°) minimizes air turbulence while maximizing airflow, ensuring uniform cooling across battery cells or controller modules. It supports stepless speed adjustment (500-2500 RPM) via PWM (Pulse Width Modulation) signals, adapting to real-time heat generation demands of NEV systems and saving energy

The fan uses a permanent magnet brushless DC (BLDC) motor with an energy efficiency rating of ≥85%—30% more efficient than traditional brushed motors. The motor has low no-load current (≤0.5A at 24V) and low operating noise (≤55dB at 1m distance), avoiding interference with NEV cabin quietness. It features a built-in motor controller with over-temperature protection (triggers at ≥120°C) and over-current protection (limits current to ≤5A), preventing motor burnout due to voltage fluctuations or blockages. The motor’s service life reaches 10,000+ hours, matching the long-term reliability requirements of NEVs

The fan meets IP6K9K waterproof and dustproof standards—the highest level for automotive cooling components—making it suitable for NEV under-chassis or engine compartment installation. The fan housing (made of high-temperature-resistant PA66+GF30 plastic) is fully sealed, with silicone gaskets at the motor shaft and wire entry points. It can withstand high-pressure hot water jets (80°C, 80-100 bar) and dust immersion, preventing water or debris from entering the motor or bearing system. This protection ensures stable operation in heavy rain, car washes, or dusty off-road conditions, critical for NEV battery safety

The fan has a slim profile (thickness: 35-40mm) and lightweight structure (weight: ≤300g), saving space in NEV tight chassis layouts. It comes with a universal mounting bracket (compatible with M4/M5 bolts) and pre-drilled holes (4 positions, spacing adjustable via sliding clips), adapting to different NEV component mounting surfaces (e.g., flat battery casings, curved controller housings). The 1.2m-long high-temperature-resistant silicone wire (rated for 150°C) allows flexible routing to NEV electrical systems, and the plug-and-play connector enables quick installation (completed in 10-15 minutes with basic tools)
