Heller

Heller is an Australian electrical appliance brand producing fans and environmental control equipment, backed by local warranty and support. Their products are widely used in grow rooms for air circulation, temperature management, and maintaining healthy growing conditions, particularly for strengthening plant stems and preventing hot spots under intense lighting.

The Heller 40cm Oscillating Wall Mounted Fan delivers wide-angle, uniform airflow across the full canopy, wall-mounted to maximise floor space rather than taking up growing area the way a standing fan does. For more targeted airflow in tents and smaller grow spaces, the Heller Clip Fan clips directly onto poles, frames and shelves, giving precise positioning without a floor-standing footprint.

Energy-efficient designs suited for continuous grow room use, helping reduce the leaf boundary layer that improves CO2 uptake and transpiration efficiency across the canopy. Fast shipping across Australia.

Frequently Asked Questions

Should I get the oscillating fan or the clip fan?
The 40cm oscillating fan suits larger grow rooms and tents needing broad lateral coverage across the canopy. The clip fan suits tighter spaces or targeted airflow on specific plants, and doesn't take up any floor space.

Why does airflow matter for plant health, not just temperature?
Moving air reduces the leaf boundary layer, which directly improves CO2 uptake and transpiration efficiency, and also strengthens stems through gentle, continuous movement, similar to wind stress outdoors.

Can Heller fans run continuously without overheating?
Yes. They're designed for continuous grow room use with energy-efficient operation suited to running 18 or more hours a day.

Does Heller ship fast within Australia?
Yes. All products ship from our Australian warehouse with fast tracked delivery Australia-wide.
