OCTAROOF EVO 800 T4 15KW
Insulated EVO casing: 100 kg/m³ rock wool and TB4 thermal-bridge class.
OCTAROOF EVO develops OCTAROOF’s high-airflow vertical-discharge concept with an insulated casing. 100 kg/m³ rock-wool insulation, TB4 thermal-bridge performance and acoustic attenuation target both energy performance and sound comfort in high-capacity roof exhaust.

Chosen where OCTAROOF-level high airflow is required but casing heat transfer, thermal bridging and radiated sound are more important design considerations.
Its core fan/motor concept is close to OCTAROOF; EVO’s main difference is the insulated casing and TB4 thermal-bridge performance. It is therefore not simply “more powerful”, but a version with a more controlled thermal/acoustic envelope.
