AHU
- AHU Primarily circulates and conditions air within a closed space, maintaining temperature and humidity levels.
- It uses re-circulated air from the building for heating, cooling, or ventilation.
- AHUS are designed for general HVAC applications without incorporating significant air purification mechanisms.
- Includes fans, coils (heating/cooling), filters, and dampers for air distribution and control.
- Commonly used in residential commercial, and industrial HVAC systems for temperature and ventilation control.
FAHU
- FAHU is designed to handle and process 100% fresh air from the external environment, ensuring improved air quality.
- It exclusively uses fresh outdoor air and filters, cools, or heats it before supplying it indoors.
- FAHUS focus on air purification, dehumidification, and fresh air supply, often complementing AHU systems.
- Equipped with advanced filters, heat exchangers, and dehumidifiers to maintain clean and fresh air supply.
- Typically used in spaces with high air quality requirements, such as hospitals, labs, or clean rooms.
