These new units are rated at 150 m3/h of air at 150 PA. They can be installed vertically on a wall, in an airing cupboard or utility room. They are only 260 mm deep, so they can also be fitted to a ceiling or in a loft space.
Test data shows that the counterflow heat exchanger achieves 88% efficiency (hence Appendix Q). There are standard G4 filters for both airflows, with a port to take an optional G6 pollen filter.
Other features include automatic thermostatically controlled summer bypass and winter defrost. Constant-volume fans maintain airflow throughout the filter life. An indicator shows when filters need attention.
Units can be commissioned in 1% steps independently in both directions, and there is 3-speed control.
