Pairs well with
If your grow room has dead spots, hot corners, or humidity sitting where it shouldn't, a wall-mounted fan is the fix — and the SeaHawk 40cm Wall Fan is the workhorse that does it without eating up floor or bench space. Wall-mounted and out of the way, it pushes air across your canopy with left-right oscillation, an adjustable tilt, and three speed settings via a simple pull cord. It runs on a quiet 50W motor with SAA-approved Australian plug and ABS blades built to last. Clean air movement, 24 hours a day, without the fuss.
Product Specifications
- Mount the fan high on the wall, angled downward to push air across the top of the canopy — this is where heat and humidity accumulate most.
- In tents, position it opposite your inline fan's intake so air moves in a diagonal loop rather than straight out.
- Run it at low or medium speed during lights-off to maintain transpiration and prevent mould without over-stressing plants.
- For larger rooms, pair two wall fans at opposite corners pointed inward for complete canopy coverage.
How to Set Up Your Wall Fan
Pairs Well With
Wall fans work best when paired with an inline extraction setup — one pulls stale air out while the wall fan keeps the canopy moving.
Carbon FiltersGood airflow and odour control go hand-in-hand. Match your extraction with a carbon filter for a complete ventilation loop.
Grow TentsThe 40cm wall fan suits tents from 1.2m x 1.2m upward. If you're setting up a new space, start with the right enclosure.
Environment ControllersAutomate your whole climate — temperature, humidity, and fan speed — from a single controller for hands-off grow room management.
Frequently Asked Questions
Is this fan suitable for a grow tent?
Not really — unless you're running a large tent with spare wall space. The 40cm head is a significant size, it requires a solid wall mount, and it doesn't clip to tent poles. For most standard grow tents, a couple of 6" clip fans with pole grips will do a better job, take up far less room, and give you more flexible positioning. The SeaHawk Wall Fan is built for dedicated grow rooms and larger spaces where a proper wall mount makes sense.
Can it run 24 hours continuously?
Yes. The 50W motor is rated for continuous operation, which is exactly what most growers need. Running it 24 hours a day is normal use and won't cause premature wear under typical conditions.
How loud is it?
The SeaHawk Wall Fan is designed for quiet operation. At low speed it produces a steady white-noise hum rather than a disruptive mechanical noise. At high speed it is audible but still well within the range most growers are comfortable with. It is not a silent fan, but it is not an annoyingly loud one either.
Does it come with an Australian plug?
Yes. The fan ships complete with an SAA-approved Australian plug. No adaptors, no extensions needed out of the box — just mount, plug in, and go.
Can the oscillation be turned off?
Yes. The left-right oscillation can be switched on or off independently of the fan speed. If you want to lock airflow in a fixed direction — say, directly at a hotspot — just disengage the oscillation mechanism.
What size room does a single 40cm wall fan cover?
A single unit is effective in spaces up to approximately 3m x 3m when positioned correctly with oscillation on. For larger rooms or dense canopies, running two units at opposing corners provides full coverage without dead zones.
