Vent Axia 437666EC Integra Plus Whole House Heat Recovery Unit

The Integra Plus heat recovery unit has been specially designed to provide ventilation for flats or internal rooms in large residential, commercial, educational or leisure applications. Balanced ventilation is achieved by using nominal 150mm ducting.
