Description
Turns a Tub of ONA Gel Into Whole-Room Odour Control
The ONA Air Cyclone sits directly on top of a 20-litre ONA gel tub and actively drives neutralised air out into the space. Gel alone relies on ambient airflow and only really treats the area immediately around it; the Cyclone pushes 121 CFM of ONA-charged air across an area of up to 464 m² (5,000 sq ft), and does it on 12 watts.
Key Benefits
- Covers up to 464 m² (5,000 sq ft) from a single 20-litre gel tub
- 121 CFM airflow actively distributes neutraliser instead of waiting for room air movement
- Five fan speeds to match output to the size of the space and the odour load
- Only 12 W draw — negligible running cost even continuously
- Runs quietly, so it suits occupied buildings and shared spaces
- Drops straight onto a standard ONA 20 L tub with no modification
Odour Escaping Beyond the Grow Space
Carbon filtration handles extracted air, but odour still escapes through doorways, loft hatches and around the tent itself. A passive gel tub sat in the corner barely touches a large room. Driving that same gel through a fan turns it into an active whole-room system, treating the ambient air rather than one corner of it.
How to Use
- Remove the lid from a 20-litre ONA gel tub and seat the Cyclone unit on top
- Position it in the room the odour escapes into — typically outside the tent, not inside it
- Start on a low speed setting and increase only as needed
- Run continuously during the flowering period, when odour output peaks
- Replace the gel tub when the surface dries out and scent output drops
