1. Sensible heat recovery
2. Total separation of fresh air & exhaust air streams
3. Heat recovery efficiency up to 80%
4. 2-side press shaping
5. Double folded edge
6. Completely joint sealing.
7. Resistance of pressure difference up to 2500Pa
8. Under pressure of 700Pa, air leakage less than 0.06%
