Product Feature

The SAS965-IAQ 4-inch IAQ Controller features a professional HD interface and integrates high-precision 4-in-1 IAQ sensing (CO₂, PM2.5, VOC, T/H). Supporting OEM/ODM private labeling and modular customization, it is compatible with AC/DC/EC motors and diverse flow systems without extra wiring. We deliver turnkey, highly adaptable solutions that empower ventilation manufacturers to significantly reduce R&D costs and enhance product differentiation across residential and commercial fresh air systems.

Key Functions

Multi-Speed Control

Supports 3 to 7 fan speeds, including a silent mode (≤29dB) and a powerful mode (20% airflow boost).
All-Screen Display

Shows all key data (VOC/PM2.5/CO₂ levels, fan speed, temp/humidity) on a single interface without page switching.
Smart Alerts

Dual alerts (pop-up + sound) for filter replacement or equipment anomaly, ensuring timely maintenance.

Schedule Control

Supports precise 0.5-24 hour timers, allowing fixed schedules (e.g., 8 AM ON, 10 PM OFF) tailored to user habits.
Remote Operation

Mobile APP remote start/stop, speed adjustment, and historical data viewing for system management while away.
Automatic IAQ Mode

Automatically switches fan speed based on sensor data (e.g., boosting speed when CO₂> 1000ppm), ensuring energy efficiency.
