PRODUCT FEATURES

Details designed around use.

Dual-flow ventilation

Supply and exhaust paths work together to circulate air.

Double-inlet fan

Uses a double-inlet centrifugal fan.

Slim housing

Different housing sizes suit different installation conditions.

DESIGN & OPERATION

From operating principles to everyday use.

Two coordinated air paths

Indoor air exits through exhaust grilles, ducts and fans. Outdoor air enters through supply fans, ducts and grilles. Check resistance and airflow separately for each path.

Dual-flow versus energy recovery

The documentation distinguishes dual-flow models from energy recovery models: dual-flow units provide supply and exhaust without a total heat exchange core. Choose an energy recovery series when that function is required.

Consider filters and installation together

The documentation describes primary and activated carbon filters; verify the configuration for each model. Confirm filters, duct connections and ceiling service access before installation.
