The iV14R-Ohio is a ventilation device fit for subsequent installation especially into thin external walls.
This fan has been developed for buildings with typically "American" walls and therefore was given a well known American name. Supplementary to the iV14R fan is the special outdoor hood in steel-grey.
The iV14R-Ohio saves heating energy with an heat recovery rate of up to 89%. Additionally, our fan, fit for the installation into thin walls, meets the requirements of the EnEV concerning the minimum air exchange.
