High airflow
Twin double-inlet fans provide independent supply and exhaust airflow.

Fresh Air Systems / QR · S Series
Twin double-inlet centrifugal fans provide separate supply and exhaust airflow for higher-volume applications. Total heat exchange and service access support operation and maintenance.
PRODUCT FEATURES
Twin double-inlet fans provide independent supply and exhaust airflow.
A large heat exchange core transfers energy.
Access panels allow maintenance of filters and internal components.
DESIGN & OPERATION
Commercial energy recovery systems supply outdoor air and remove indoor air together. Check occupancy, duct resistance, zoning and ceiling space as well as airflow.
Supply and exhaust air travel on opposite sides of the core, exchanging heat and moisture. Performance depends on temperature, humidity and operating configuration.
Primary and subsequent filters perform different tasks; confirm the configuration by model. Access doors support filter servicing and internal inspection. Allow sufficient opening clearance.
