The 100mm Direct Air Kit from ACR Heat Products is designed to provide a direct external air supply to compatible stoves, improving combustion efficiency and ensuring stable, reliable performance. By feeding air from outside, it reduces the need to draw warm air from the room, helping maintain indoor temperatures and overall comfort.
With a larger 100mm diameter, this kit is ideal for stoves requiring a higher airflow capacity. The 1.2 metre duct length offers flexibility during installation, allowing it to be routed efficiently to suit a variety of room layouts and property types.
This system helps eliminate draughts and uneven airflow often associated with stoves drawing air internally. By delivering a controlled and consistent air supply directly to the combustion chamber, it improves flame stability, fuel efficiency, and overall stove responsiveness.
Manufactured from durable materials, the kit is built for long term use and reliable operation under varying conditions. Its discreet design ensures it integrates neatly into your installation without affecting the appearance of your living space.
Important:
Please provide your stove serial number prior to purchase so compatibility with your ACR appliance can be confirmed.
