ERV-THP Series: Ventilation Fan & Air Ventilation Systems for Indian Homes
The ERV-THP Series is Astberg's flagship range of energy recovery ventilation fan systems, designed to deliver continuous, balanced air ventilation for homes, apartments, and semi-commercial spaces across India. Unlike a basic exhaust fan that only removes air, every unit in this series — from the AHE25 (250 CMH) to the AHE130TH (1300 CMH) — exchanges stale indoor air for filtered fresh air while recovering 78–84% of the heating or cooling energy that would normally be lost in the process.
How the ERV-THP Series Improves Air Ventilation
Most Indian homes rely on opening windows or running a single exhaust fan for air ventilation, which either lets in outdoor pollution or wastes conditioned air. The ERV-THP Series solves both problems at once. A heat-exchange core inside each unit transfers temperature and humidity between the outgoing and incoming air streams, so fresh air enters the room pre-conditioned, not at raw outdoor temperature. This keeps indoor air consistently fresh without forcing your AC or heater to work harder to compensate.
Choosing the Right Ventilation Fan Capacity for Your Space
Airflow capacity, measured in CMH (cubic metres per hour), determines which model suits your space. The AHE25 and AHE35 are built for single rooms or small apartments, the AHE50 and AHE80 cover mid-sized homes with multiple rooms, and the AHE130TH is sized for larger villas, halls, and semi-commercial installations. As a general rule, larger or more occupied spaces need higher CMH to maintain effective air ventilation throughout the day.
Why Filtration Matters for Air Ventilation
Air ventilation isn't just about moving air — it's about moving clean air. Every ERV-THP unit filters incoming air through H13-grade HEPA and carbon filtration, removing fine dust, pollen, and airborne pollutants before they enter your home. This matters in Indian cities where outdoor AQI is often poor, since a ventilation fan without filtration can end up pulling pollution indoors rather than keeping it out.
