I'm just about to start and wire a load of refurbished industrial units which have offices at the back but no natural ventilation. Aparently you need 10 l/s per person per office of extraction. The problem is i have to allow fresh air to replenish the used air, but the only place for inlet / outlet grills to the out side are about 2 meters above the office ceiling so a air brick at low level is not possible. Has anyone else come accross this type of problem and is there some king of dual unit fan that extracts and replaces the air.
Any help much appreciated.
