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.
