FAQs
Why should schools choose this over simply opening windows?
Opening windows leads to uncontrolled temperature swings, outdoor noise pollution (traffic, construction), and the entry of unfiltered pollutants (pollen, PM2.5). The Airwoods ERV provides controlled, filtered, and whisper-quiet ventilation while keeping CO2 levels below 1000ppm automatically, which is proven to improve student concentration and grades.
Is the unit safe to be placed directly in a classroom with active children?
Yes, safety is our top priority. The unit features: Anti-Tilt Structure: Secured with L-shaped wall brackets to prevent tipping. Triple Protection: Front panels and filter access are secured with keys and screws to prevent unauthorized access. Top Air Design: Air intake and outlets are located at the top to keep them out of reach of children. Child Safety Lock: The smart controller can be password-locked to prevent tampering.
Can this system handle extremely cold winters?
Absolutely. The unit is equipped with a 2200W intelligent PTC auxiliary heater and automatic defrost functions. It can operate reliably in temperatures as low as -25°C, ensuring that the fresh air delivered into the classroom is always at a comfortable, warm temperature.
How effective is the air filtration against PM2.5 and allergens?
The unit comes standard with a dual-stage filtration system (G4 + F7). The F7 medium-efficiency filter removes over 95% of PM2.5 particles, dust, and pollen. An optional medical-grade sterilization filter is also available for enhanced protection against bacteria and viruses.
How much maintenance does the unit require?
Maintenance is simple and cost-effective: Filters: G4/F7 filters are easily accessible via the front panel. We recommend checking them every semester. Exchanger: The polymer heat exchanger is washable and mold-resistant, with a lifespan exceeding 10 years. Access: Since it is floor-standing, no ladders or specialized ceiling access equipment are required.
Can I manage multiple units across different classrooms?
Yes. The AV-TPF85 EFW supports Tuya Wi-Fi App control for individual management via smartphone and is fully compatible with BMS (Modbus) systems. This allows facility managers to monitor air quality, set schedules, and control units across an entire campus from a single central office.
How many units do I need per classroom?
Generally, one AV-TPF85 EFW unit is sufficient for a standard classroom of 20-30 students. Based on international standards (like DIN EN 13779), we calculate approximately 30m³/h of fresh air per student to maintain CO2 levels at a healthy 1000ppm.
