Smart air mixing for uniform, stable climate
The Vario Air-Mix is designed for circulating large volumes of barn air to keep poultry environments more stable, dry, and productive.
With airflow up to 21,125 m³/h and a throwing range of 22 meters, this circulator helps maintain uniform temperature and humidity throughout the building – ideal for layer houses with tight climate needs.
Whether installed with the air intake at the top or bottom, the fan ensures warm, moist, stable air is recirculated efficiently, reducing temperature gradients and avoiding heat loss. It also aids in removing excess humidity, improving litter condition, and reducing ammonia and associated health risks or respiratory diseases.

The Vario Air-Mix advantage
High-volume, directional airflow
With a powerful airflow, the Vario Air-Mix mixes warm and cool zones evenly. Adjustable airflow outlet lets you set direction and throw, improving microclimates and comfort in every corner of the house.
Flexible air intake configuration
Available in two variants: with air intake at the bottom, ideal for mixing rising warm air, and with air intake at the top, suitable for layered airflow in setups with ceiling inlets. This flexibility allows you to match the fan to your specific ventilation layout and farm design.
Reduces moisture, improves litter
Constant air mixing reduces relative humidity and helps keep bedding dry, cutting down on ammonia formation and improving bird welfare and productivity.
Ceiling mountable & speed controllable
Mounts quickly using chain links to ceiling structures. Available with variable speed control for fine-tuned airflow, especially useful in seasonal transitions or multi-zone barns.
