Start with the job your ventilation must do

A circulation fan moves air inside the room. An inline fan or acoustic box fan extracts it. A carbon filter treats the outgoing air. Plan these parts together while keeping their separate functions in mind.

Match airflow to heat, incoming air and duct resistance. Then check duct diameter, the filter connection and the fan’s control method. This helps you avoid a restriction in one part of the setup.

Airflow through the whole setup

A rated airflow figure is not a promise for your tent. Filters, bends, duct length and incoming air affect the actual flow. Check the fan curve at the expected system resistance.

Connections and speed control

Measure the connections on the fan, ducting and filter. A reducer joins sizes but cannot enlarge a narrow duct. Check the motor type, supported control method and maximum load before choosing a controller.

Duct clamps for your ventilation connections

Choose a clamp range that fits your ducting and connection. Check the joint and any sealing materials separately.

Build climate control around the whole setup

Move from measurements to choices

Measure temperature and relative humidity in a representative position, away from direct light and hot air. Compare light and dark periods. One reading does not show the pattern; record the time and equipment settings too.

Circulate, exchange and treat the air

Choose circulation for movement inside the room and extraction for air exchange. Keep incoming-air openings clear. Select a carbon filter for the airflow and connection you use, and avoid unnecessarily long or narrow duct runs.

Match controllers and climate equipment

A controller must suit the fan motor and electrical load. Choose heating or cooling for the actual conditions and installation needs, rather than a product name alone. For more involved setups, we can help assess models, dimensions and required components.

Allow access for checks and maintenance

Keep filters, duct clamps, sensors and connections accessible. Check airflow and joints after installation. Repeat measurements when you change lighting, the duct route or equipment settings.
