The Vent-Axia through-the-wall range of heat recovery ventilation is a whole home ventilation system that supplies and extracts air continuously at a low rate with the facility to be boosted as required.
The unit is normally installed in the attic space or cupboard and rigid ducting supplies fresh filtered air to the habitable rooms and extracts stale polluted air from the ‘wet’ rooms (kitchen, bathroom). Supply and extract diffusers are fitted to the ceilings and are adjusted to balance the system.
