How to Choose the Right Smart Fresh Air Controller for Your Project

When selecting a fresh air control panel for commercial and intelligent building systems, air detection accuracy and system compatibility are the core purchasing factors. Ordinary ventilation controllers only support simple fan speed control without air quality data feedback, which cannot meet modern building IAQ (Indoor Air Quality) management standards.

This multi-functional fresh air controller G3 is designed for professional building ventilation projects. It integrates PM2.5, CO2, VOC, temperature, and electrochemical CO sensors, achieving full-range real-time indoor air quality monitoring. Unlike ordinary CO sensors, the electrochemical CO module provides high-precision and stable detection, which is essential for closed office spaces, underground malls, and centralized ventilation environments to avoid carbon monoxide hazards.

For intelligent building centralized control needs, this device supports Modbus RS485 industrial communication, which can be seamlessly connected with building automation systems, HVAC host equipment, and central control systems to realize unified data collection and linkage control. For remote operation and after-sales maintenance, built-in Tuya WiFi and Tuya APP remote monitoring functions allow engineers and property managers to view air quality data and adjust ventilation equipment status anytime and anywhere.

In terms of installation and adaptation, the standard 86-type wall-mounted design and wide AC 110–230V voltage adaptation meet the wiring requirements of most commercial buildings. It is the preferred professional control terminal for new building ventilation transformation, smart office, hotel, and commercial real estate projects.
