The 48V-DC 250mm 105W Axial-Flow Industrial Fan is optimized for high-volume, low-pressure airflow in industrial settings, where moving large air quantities efficiently is prioritized. Its 250mm diameter and 105W power rating make it a versatile choice for applications requiring rapid air exchange, such as ventilation shafts or open-area cooling. The axial-flow design—where air moves parallel to the fan’s axis—minimizes pressure drop, making it ideal for systems without complex ductwork.
Axial-Flow Design
The propeller-style impeller (12 blades) generates airflow parallel to the motor shaft, with a tip speed of 32 m/s optimized for low resistance. This design achieves 90% airflow efficiency in unobstructed environments, with minimal pressure loss when used in grille-equipped openings. The blade angle (15°) balances airflow volume and energy consumption, avoiding the inefficiencies of steeper angles at low static pressure.
Lightweight and Compact
Constructed from fiberglass-reinforced plastic (FRP), the fan weighs 4.2kg—30% lighter than steel-bodied alternatives—simplifying installation in overhead or wall-mounted positions. The compact profile (depth 150mm) allows integration into tight spaces such as machine enclosures or between structural beams.
Low Noise Operation
Aerodynamic blade profiling reduces turbulence at the blade tips, resulting in 65 dB(A) operation at full load—quieter than a conversation (60 dB(A)) . The motor's rubber isolation mounts further dampen vibration, with sound transmission reduced by 15% compared to rigidly mounted fans.
Wide Temperature Range
Tested to operate reliably in -40°C to 85°C ambient temperatures, the fan suits extreme environments such as frozen food storage facilities and desert-based solar power plants. The impeller's FRP material retains flexibility at low temperatures and resists warping at high heat, while the motor's insulation (class H) withstands winding temperatures up to 180°C.
Industrial Ventilation: Provides fresh air intake in manufacturing plants (e.g., automotive assembly lines) and mines, with airflow rates matching OSHA’s recommended 20 cfm per worker.
Cooling Towers: Augments heat dissipation in cross-flow cooling towers for HVAC systems, increasing heat rejection by 15% when mounted on tower fill surfaces.
Agriculture: Regulates temperature in greenhouse facilities (3,000-10,000 m²) growing high-value crops (e.g., tomatoes, cannabis), maintaining 25-30°C daytime temperatures.
Marine Applications: Ventilates engine rooms and cargo holds in commercial vessels, with salt spray resistance tested to IMO standards (500 hours of salt fog exposure).
Q: What is the airflow capacity?
A: The fan delivers 2,000 m³/h maximum airflow at 1,800 RPM, with a linear reduction in output as speed is adjusted via control signals.
Q: Can it be used in outdoor environments?
A: Yes, the IP55 protection rating ensures resistance to dust ingress and low-pressure water jets (12.5mm nozzle at 10 liters/min), making it suitable for uncovered installations such as rooftop ventilation.
Q: How do I reduce vibration during operation?
A: Use the supplied rubber mounting pads (Shore A 60 hardness) between the fan flange and mounting surface, which compress to absorb vibration. For ceiling installations, flexible duct connectors (300mm length) further isolate structural transmission.
