Product Overview
The AOSUNFAN Air Curtain (Model AC-C48M) is a heavy-duty centrifugal airflow barrier designed for large commercial doorways and industrial entrances. With a 48-inch (122 cm) width and 220V high-torque motor, this Air Curtain generates 8-15 m/s high-velocity airflow to create a seamless thermal and particulate barrier (ASHRAE 90.1 compliant). Featuring powder-coated galvanized steel housing (IP55-rated) and backward-inclined aluminum blades, it delivers 2,500-5,500 m³/h airflow with noise levels ≤60 dB(A) (ISO 3744 tested). Equipped with dual-control modes (remote/PIR sensor) and BMS integration via Modbus RTU protocol for smart building synchronization.
Product Features
Centrifugal Force Optimization
Multi-wing impeller design increases airflow efficiency by 40% vs. axial fans (AMCA 210 certified).

FAQ
Q1: How does this Air Curtain prevent insect entry compared to standard models?
Our Air Curtain creates a 15 m/s downward airflow "wall" (tested per EN 12101-6) that blocks 98% flying insects while maintaining temperature.
Q2: Minimum installation height recommendation?
Optimal performance at 2.5-3.2m mounting height with 10° downward airflow angle.
Q3: Filter maintenance schedule for dusty environments?
Clean washable G4 filters every 2 weeks; replace annually (included in starter kit).
Q4: Integration with existing HVAC systems?
Supports BACnet MS/TP protocol with 0-10V analog signal input for synchronized climate control.
