Grow Room Fans

Duct fans are designed to control the environmental conditions in your grow room, helping to keep temperature and humidity levels optimal, while drawing in a fresh supply of CO2 that your plants can use to photosynthesise. We now offer Hyper Fans and Revolution Vector EC systems that feature...

Both by systemair both EC only difference is the repackaging and marketing towards growers

How do we attach some vents to these bad boys? I want that hum to finally be gone

Kudos to their marketing guy! Way to blow smoke!


BS no way on Earth anything moving is frictionless.

BS sorta... might be true if they cherry picked figures from the best and worse parts of the performance curve.

This is about the only thing that's critical.

BS.

This is true, a lot of products aren't engineered or built to be as leak-proof as weed growers need them to be.

And if that fan controller is vector controlled (field-oriented control (FOC) ) it will most likely reduce hum.

I think instead of frictionless they mean less friction than an AC on a fan speed controller (hum)
The reason I'm asking online is these guys with the silent revolution fan refuse to show a video, becoming tempted to just go to a hydro shop and say I'm not buying unless they unpack it and show me

Then they need to look up what frictionless means.

I usually carry a wad of cash with me when I plan to have stores open something up and show me on the spot.
Just pull out the wad and tell them: I'm here to spend money if that does what you say it does.
Keep in mind fans get louder under load.

I have 2 6" on my tent turned down the real noise is from the humming rather than the airflow I'll happily pay for 2 ECs if I could get them 200 each but they're like hello £500+
The thought of 1 12" running the double square foot tent isnt to my liking I think it will be louder
Also planning getting smaller clip on oscillation fans(cheap 12" are way overpowered)
closed cell foam underneither the tent
I'm not sure if upgrading to a budboxpro (steel frames) from cheap amazon tents is going to help the matter but its sexy I'm doing it
