Total heat exchange
The core transfers energy between incoming and outgoing air.

Fresh Air Systems / QR · P Series
Supply and exhaust airflow with total heat exchange renews indoor air. Multiple filters, service access and optional controls support everyday operation and maintenance.
PRODUCT FEATURES
The core transfers energy between incoming and outgoing air.
Internal filters treat air before it enters the space.
Switch, LCD and wireless controls are available depending on the configuration.
DESIGN & OPERATION
Filtered outdoor air enters the room while exhaust air leaves through a separate path. The total heat exchange core transfers heat and moisture between the streams, combining ventilation with energy recovery.
In summer, cooler exhaust air preconditions incoming air; in winter, warmer exhaust air preheats it. Select the unit with the air-conditioning system and operating conditions in mind. It does not replace air conditioning.
Primary filters capture hair and coarse dust. Subsequent media address finer particles and odors according to configuration. Confirm filter type, grade and activated carbon availability for the selected model.
The documentation describes clips and hinged access doors for inspecting filters, the core and motor. Allow room for access and servicing when designing the ceiling.
