External air inlet Ø 100 for cast iron fireplaces, which provides fresh air directly from outside. Installation does not require additional elements such as the passage-inlet pipe.

For proper operation, each fireplace needs the right amount of air. Its scarcity often becomes one of the main problems of the malfunctioning of an insert. In order for the fireplace to not cause us any problems, it must have approx. 8-10 m³/h of air supplied per 1 kg of wood. If there is no other way, it gets air from the room in which it is located. And because it is most often located in the living room, i.e. a place where we often spend time, in reality indirectly "takes" the air away from us.
