Detailed Product Description

Industrial-Grade Axial Flow Ventilation System
Engineered for Diverse Climate Control Demands


Product Highlights

  1. Advanced Airflow Management
    • Delivers precision airflow adjustment (120–600 m³/h) with 80–220 Pa static pressure capacity, optimized for extended duct networks in multi-story structures.
    • Dual-phase impeller technology reduces turbulence by 34%, enhancing energy efficiency (24–100W power range).
  2. Professional-Grade Construction
    • Aerospace-grade aluminum alloy housing with IP54-rated ingress protection for humidity-prone environments.
    • ECM (Electronically Commutated Motor) with 100% copper windings ensures 50,000+ hours MTBF (Mean Time Between Failures).
  3. Intelligent Safety Architecture
    • Dual-layer thermal monitoring: Triggers auto-shutdown at 85°C (185°F) and reactivates at 65°C (149°F).
    • Current stabilization circuitry prevents overloads during voltage fluctuations (90–265V compatibility).
  4. Acoustic Optimization
    • IsoVibe™ anti-resonance mounts and aerodynamic grille design achieve 32–58 dB(A) operation (EN ISO 3744 certified).
    • Night-mode reduces noise to 28 dB(A) for residential/sleeping areas.
  5. Modular Compatibility
    • Supports Ø100mm/150mm circular ducts with universal flange adapters (AS/NZS 1668.1 compliant).
    • Pre-wired terminals enable integration with BMS (BACnet/IP or Modbus protocols).

  • Integrated with smoke evacuation systems for lab safety.

C. Residential Complexes

  • Balances positive/negative pressure in multi-zone HVAC systems.
  • Compatible with smart home platforms (Google Home, Alexa).

D. Commercial Offices

  • Cyclic operation syncs with occupancy sensors to cut energy use by 40%.
  • Removes VOCs from printing rooms via activated carbon pre-filters.

Logistics & Support

Packaging Protocol

  • Triple-layer corrugated boxes with EPS shock absorption (ISTA 3A tested).
  • RFID-tagged for inventory tracking; moisture-resistant desiccant included.

Global Shipping

  • FOB Foshan: 3–8 business days for OEM orders (5000-unit monthly capacity).
  • DDP options available for EU/NA markets (VAT/GST pre-cleared).

After-Sales Framework

  • 5-year motor warranty + 2-year parts coverage.
  • 24/7 remote diagnostics via AR-assisted troubleshooting.

Procurement Details

  • MOQ: 1 unit (sample orders accepted).
  • Payment: T/T, LC, or Escrow (Crypto payments negotiable).
  • Customization: Branding, voltage (110V/220V), and duct adapters (square/oval).
