If you’re running a small grow and need quiet, powerful ventilation, the EnviroVent Silentub 100 is where it’s at. This compact axial in-line fan with a 100mm diameter and airflow up to 90m3/h is designed for quiet, continuous ventilation in smaller spaces. Plus, its internal motor is mounted on silent blocks that reduce vibration, with an insulated body that further reduces sound output — making it one of the quietest fans in its class. It supports both intermittent and continuous operation, and can be installed in false ceilings or tight ducting runs with a removable bracket for easy maintenance. For increased airflow in mid-size setups, the Jetline 160 delivers quiet and efficient performance. Growers who go big or those running commercial spaces will benefit from the high-capacity Jetline 200 — a vent fan engineered for max airflow and low noise operation.
