Fan sizing
Fan sizing and air distribution needs to be designed appropriate to the output characteristics desired. At recommended flow rates of between 100 and 150 m3/h per m2 for general commercial and industrial applications, fan sizing and positioning must consider collected air, system pressure drops at all points of movement and distribution, efficiency losses at distribution points, the required rates of space air exchange, and any heating, humidity, or moisture drying demands.
As a rule of thumb, use 1m2 of air collector for each 100m3/h of air flow.
Some suggested fans include:
Gigabox GB series
suggested fans: inline centrifugal GB series
suggested fans: inline CA-MD series
CA-MD series
For medium to smaller air flow volumes against high resistances. Universal application for domestic, commercial and industrial purposes.

See the performance datasheets in the Downloads section for model-specific flow curves.
For buildings with long duct runs or high resistance, supplementary in-line fans are recommended. SVPro lists compatible fan models on the Suggested Fans page, selected to match the collector flow rates.
The Suggested Fans page lists in-line duct fans matched to the pressure and flow range of SolarVenti collectors. Models are selected to avoid throttling the collector output. Contact SVPro for the current recommended list.
Each collector has an internal 12V DC fan matched to its output. Supplementary fans in the duct must not create back-pressure that stalls the collector fan. SVPro specifies fans with compatible duty points.
SVPro can advise if an existing fan is compatible once you provide the flow rate and static pressure characteristics.
This allows 24-hour operation for applications with a continuous drying requirement.
The recommended flow range for one SVPro collector is 90–120 m³/h. The collector has a solar collection area of approximately 1.26 m² per module. Multiple modules are combined to scale total airflow linearly.
Pressure drop through one module is approximately 25 Pa at 50 m³/h, 75 Pa at 100 m³/h, and 175 Pa at 150 m³/h. Fan selection must account for this to avoid throttling collector output.
