Designed for safety-critical and low-noise environments, this 300mm axial fan combines a protective guard grille with ultra-quiet operation (66 dB(A)). Powered by a 48V DC motor (Model BLDC92) and a 5-blade fiberglass-reinforced impeller, it delivers 2300 m³/h airflow at just 80W power consumption. Ideal for public spaces and sensitive equipment, its IP44-rated housing provides dust/splash protection while ensuring silent performance.
Safety-First Design with Guard Grille
Integrated protective grille prevents accidental contact with blades, meeting safety standards for schools, healthcare facilities, or accessible public areas.
Ultra-Low Noise Operation
At 66 dB(A), it operates quieter than a conversation (70 dB), perfect for libraries, offices, or noise-sensitive medical devices.
DC Power Efficiency
Wide voltage input (36–57V DC) supports solar/battery systems, consuming only 80W—ideal for off-grid or energy-efficient applications.
Easy Speed Tuning & Monitoring
Simple 0–10VDC/PWM control with FG tach signal (4 pulses/rev) enables real-time RPM adjustments and fault detection.
Public Space Ventilation: Schools, museums, or retail stores requiring safe, quiet airflow.
Solar-Powered Systems: Attic fans, greenhouse cooling, or off-grid ventilation.
Medical/Diagnostic Equipment: Cooling MRI machines or lab devices where silence is critical.
Accessible Electronics: Low-profile cooling for kiosks, ticket machines, or interactive displays.
Q1: Why choose a guarded fan over open-frame?
Essential for public/commercial installations to meet safety regulations (e.g., IEC 60335) preventing finger access to blades.
Q2: Can it run 24/7 on solar power?
Yes. Low 80W draw pairs well with 200–300W solar panels, and wide voltage range handles battery charge fluctuations.
Q3: How does FG pulse count (4/rev) help?
Higher resolution than standard 2-pulse fans allows finer RPM monitoring for predictive maintenance alerts.
Q4: Is the grille removable for cleaning?
Yes. Tool-free clips allow quick removal, but reinstall before operation to maintain safety compliance.
Q5: Why fiberglass-reinforced blades?
Provides 30% more impact resistance vs. standard plastic, reducing fracture risk in high-vibration environments.
