EcoFlow is one part of a complete Nafas system that senses, filters, and manages your building's air.
01
In-duct Monitoring
Sensors inside the AHU and ductwork track air quality at the source, before it reaches the space.
02
Indoor monitoring
A monitor in the occupied space measures what people actually breathe. Wall-mounted or on a stand.
03
Building dashboard
Facilities teams see air quality across every space, track trends and insights, and pull ESG and certification reports.

Frequently Asked Questions
Frequently Asked Questions
Frequently Asked Questions
Can EcoFlow be retrofitted into an existing HVAC system?
Yes. EcoFlow can be integrated into many existing AHUs, FAHUs, and FCUs without replacing the entire HVAC system. A technical assessment is conducted to confirm dimensions, airflow, access, electrical requirements, and the appropriate configuration.
