Application Guide
Use this filter as part of an intake or exhaust ventilation system in a grow tent, hydroponic growing room or greenhouse. Match it with 100 mm nominal ducting and a compatible inline fan; the fan and ducting are separate ventilation components.
- Fit the included pre-filter before use to help keep larger particles from clogging the carbon filter.
- Use the supplied filter belts to position the filter in the ventilation arrangement.
- Treat the quoted maximum airflow as the manufacturer’s filter rating, not a guaranteed installed-system airflow.
