MIC – Mixing Inlet Chimney

The Mixing Inlet Chimney or MIC for short is unique in its kind. It has a mixing fan mounted underneath the diffuser plate. When the main fan speed is lowered during the minimum ventilation, the mixing fan in the MIC ensures a steady throw of air. The MIC creates a film of warm air that carries the incoming fresh air. This means that when the incoming fresh air is colder, it will not fall down so easily, but will glide along with the warm air that goes through the mixing fan.

The MIC is used to take fresh air into the house. The damper unit in the Mixing Inlet Chimney controls the capacity of the incoming fresh air. In winter times, the advantage of the mixing fan underneath the diffuser plate is that it mixes the warm air in the house together with the cold incoming air. Doing this ensures an optimal throw of the air through the house.

The Mixing Inlet Chimney is ideal for negative pressure ventilation concepts, that require the use of chimneys where air inlets are not able to work or cannot be fitted in either the ceiling or the side walls.

The exhaust in these types of houses is often done with exhaust chimneys.

This chimney requires a fan in the bottom section (which can be supplied by TPI).
All of our chimneys are made out of high-quality polyurethane.

All of the TPI exhaust and inlet chimneys are available in the following dimensions:
