5 Features
5-3 FRESH-UP operation
Both the excessive supply mode and the excessive exhaust mode are selectable.
This function creates a more comfortable air environment.
5-4 Element (HEP element)
Material
The heat exchanger element adopts a new paper of high permeability. The material recovers exhaust humidity at a speed of 2 times of
the previous model.
The material is flame-retardant for safety.
The fungiproof design also keeps the air clean.
Structure
The heat exchanger element is designed without moving parts for higher durability and reliability.
The supply air passage and the exhaust air passage are arranged in right angle to prevent the supply and exhaust air from getting mixed.
Supply Fresh-up
(Excessive outdoor air supply)
Exhaust Fresh-up
(Excessive Exhaust air supply)
Detail
Supply air volume can be set at a higher level than the
exhaust air by the remote control. Exhaust air volume can be set at a higher level than the
supply air by the remote control.
