1. The fresh outdoor air is filtered with the intake filter,
and the heat is recovered with the Lossnay Core
(during winter; heated and humidified, during summer;
cooled and dehumidified). Then it is supplied by the
supply fan.
2. The optional high efficiency filter is placed between the
Lossnay Core and supply fan, to refilter the air that has
been filtered by the intake filter.
3. The stale air passes through the damper, and is filtered
by the exhaust filter. The heat is recovered with the
Lossnay Core, and then discharged by the exhaust fan.
4. The bypass passage for normal ventilation bypasses
the air on the exhaust side. If the bypass damper is
closed, the stale air will be directly drawn in by the
exhaust fan and discharged.
