AIRWOODS Vertical ERV for School | School Ventilation
Key Features
Designed for School Environments
The freestanding vertical design is ideal for classrooms and educational facilities. An L-shaped wall-mounting bracket provides stable installation without ceiling mounting. Features include an anti-tilt structure, secured maintenance access and child safety lock for added protection.
Smart CO2 Control & BMS Integration
The built-in LCD touchscreen displays indoor temperature, humidity and CO2 levels. Supports adjustable CO2 control, scheduled operation, WiFi remote management and Modbus communication for building management system (BMS) integration.
Quiet Operation for Classrooms
Equipped with EC dual-inlet fans and internal acoustic insulation, the system delivers quiet ventilation for learning environments. Sound pressure levels start from 30 dB(A) at 1 meter on low speed, helping maintain a comfortable classroom atmosphere.
High-Efficiency Heat Recovery & Cold Climate Protection
The counterflow total heat exchanger recovers heat and moisture from exhaust air, with temperature recovery efficiency of up to 93%. Standard G4 and F7 filters help improve indoor air quality, with F7 filtration removing over 95% of PM2.5 particles.
Automatic defrost, a 2.2 kW PTC electric heater and summer bypass support year-round ventilation. The PTC heater activates automatically below -1°C to help prevent frost buildup. The system is designed for reliable operation in temperatures below -25°C.
