Compact Design for Easy Installation and High Ventilation Efficiency with Cabinet Centrifugal Fan

Product Application & Technical Specifications

1. Air Circulation System - Cabinet-Type Low-Noise Centrifugal Unit
Applications

• Industrial Ventilation: Efficiently eliminates hazardous airborne particles, thermal buildup, and chemical vapors from production areas, ensuring OSHA-compliant workspaces.
• Commercial Climate Control: Maintains optimal indoor air quality (IAQ) in hospitality venues and retail complexes through continuous air renewal systems.
• Residential Solutions: Provides moisture control and pollutant removal for subterranean spaces (cellars, parking structures) via duct-integrated installations.

Core Advantages

• Acoustic Optimization: ≤55 dB(A) operational noise level minimizes workplace auditory interference.
• Space-Adaptive Architecture: Streamlined cabinet dimensions (standard 600×600×800mm) enable wall-mounted or ceiling-embedded configurations.
• Dynamic Airflow Management: Achieves 1500-4500 m³/h adjustable airflow with 80% static pressure efficiency.
• Maintenance Economy: Sealed bearing units and corrosion-resistant housing extend service intervals to 20,000+ hours.
• IP54 Protection: Multi-stage filtration prevents particulate ingress (>0.5μm filtration efficiency).

2. Drive Unit - Synchronous Sealed Metal Motor
Performance Highlights

• Hermetic Engineering: Triple-labyrinth seal structure with NEMA 4X certification resists particulate/dust penetration (tested under IEC 60034-5).
• Energy-Smart Operation: 0.92 power factor and IE4 efficiency class reduce kWh consumption by 18-22% versus asynchronous counterparts.
• Precision Motion Control: ±0.5% speed consistency through closed-loop feedback system (RS485/Modbus protocol compatible).
• Rugged Construction: Die-cast aluminum enclosure (8mm wall thickness) withstands 7G vibration loads per ISO 10816-3.
• SilentDrive™ Technology: Integrated anti-resonance mounts achieve <65 dB operational acoustics.

Industrial Implementation
Medical HVAC Systems: Powers laminar flow units in OR ventilation with 99.97% uptime reliability.
Manufacturing Automation: Synchronizes with PLC-controlled production line exhaust networks.

3. Air Movement Core - Multi-Blade High-Pressure Impeller
Aerodynamic Features

• Pressure Enhancement: Generates 800-1200 Pa static pressure through 32° backward-curved airfoil blades.
• Volumetric Efficiency: Delivers 15% increased CFM output versus conventional radial designs (AMCA 210 verified).
• Energy Recovery Design: Vortex-reduction hub geometry improves system COP by 12-15%.

Mechanical Configuration

• Space-Optimized Profile: 300-800mm diameter options with 3:1 aspect ratio for ductwork compatibility.
• Dynamic Balancing: ISO 1940 G2.5 balance grade reduces axial vibration to <2.5 mm/s RMS.
• Maintenance Accessibility: Snap-fit blade assembly allows tool-free disassembly for CIP cleaning.

Material Science

• Aerospace-Grade Aluminum: 6061-T6 alloy construction with HVOF coating resists erosion (tested to 25 m/s particulate flow).
• Fatigue Resistance: Finite element-optimized stress distribution ensures 100,000+ cycle durability.

Product Parameters

1. Wide Applicability: Suitable for industrial ventilation, HVAC systems, air purification, and other fields, meeting diverse industry needs.

2. Strong Customizability: Can be customized according to specific application requirements, such as different sizes, materials, and blade numbers, to achieve optimal performance.

3. Enhanced System Performance: Works well with other components to improve the overall performance of ventilation or air treatment systems, increasing system efficiency and reliability.
