Asthor - Greenhouses Roof Ventilations and Fans

Asthor ventilations whether manually handled or automated, let us achieve an appropriate temperature and humidity: Roof ventilations: Simple of ¼ bay or ½ bay, double up to 45%.

The horizontal airflow fans can reduce the inside humidity, lower the temperature and get more uniform temperature and humidity all inside the greenhouse.
