Product Application

Engineered for commercial kitchens, hospitality venues, educational institutions, and corporate dining facilities, this high-pressure, low-noise grease extraction fan addresses critical challenges in油烟和异味管理. Its robust airflow rapidly evacuates grease-laden air while maintaining indoor air quality. Key advantages include:

• High-pressure airflow to overcome duct resistance in complex ventilation systems, enabling efficient long-distance grease removal.
• Noise-optimized operation (≤55 dB) ensures compliance with urban and residential noise regulations.
• Odor-neutralizing capability through integrated airflow dynamics, enhancing workplace comfort and customer experience.
• Adaptive performance for diverse cooking environments, from wok stations to grilling zones.

Body Material

The fan's structural integrity derives from galvanized aluminum-zinc alloy casing, featuring:

1. Corrosion resistance with 3x enhanced durability versus standard steel in high-humidity/chemical exposure environments.
2. Thermal stability (-30°C to 300°C operational range) prevents warping under extreme kitchen temperatures.
3. Aerodynamic surface finish reducing airflow turbulence by 18% compared to textured materials.
4. Lifecycle cost efficiency – 10-year anti-corrosion warranty with 40% lower maintenance frequency.

High-Performance Core Motor

Certified IE4 premium efficiency motor incorporates:

• IP54-rated enclosure: Resists particulate ingress (≤1mm solids) and 360° water-jet protection (IEC 60529 standard).
• Class-F insulation system: Withstands 155°C continuous operation, paired with oxygen-free copper windings for 99.3% conductivity.
• Dual-sealed ball bearings: NSF H1 food-grade lubrication ensures 50,000-hour MTBF (Mean Time Between Failures).
• Smart thermal protection: Auto-shutdown at 130°C with fault diagnostics via LED indicators.

Multi-Blade Centrifugal Impeller

The aerodynamically optimized impeller delivers:

• 62-blade vortex design: Generates 12% higher static pressure (up to 1200 Pa) versus conventional 36-blade units.
• PTFE-infused coating: Reduces grease adhesion by 90% (ASTM D3712-18 test protocol) with self-cleaning properties.
• Dynamic balancing: ISO 1940 G2.5 certification minimizes vibration to <2.5 mm/s at full load.
• Modular replacement: Individual blade replacement system cuts maintenance costs by 35%.
