Growing concern about Indoor Air Quality makes a right choice of ventilation fans more critical. Nobody believe the existing fans work right? ...why? It's because the current fans can't generate the capture velocity strong enough to carry contaminants to the exhaust hood. It shows the alternative solution of the swirler fan.

1. Do Fans Work Right?
I mean, your ventilation fans

2. Let’s begin with a desk fan

3. At the front side of the fan, we can feel the wind.
Yes, the wind meant to blow out!

4. What about the back side?
Do you feel any wind? Certainly NOT!

5. What about the suction of a ventilation fan?
Do you feel any wind near the fan?
…..Slightly? Barely? Uh?

6. 10 inches
What about the distance of just 10 inches?
Do you feel any wind? Certainly NOT!

7. Put your hand underneath a range hood.
Do you feel any wind? ... Barely? Slightly?

8. Half of a vent fan’s function is blowing out bad air.
The latter half is to capture contaminants from the
source.
It seems something is WRONG with CAPTURING.

Then, what’s the Matter?
Ventilation experts may agree to the following
conceptual drawing on how an ordinary fan works.
Since an ordinary fan does NOT have Ventilation Focus or direction, It’s
suction power rarely reaches to pollution source. It’s because ordinary
fans can NOT make tangible wind. In other words,
FANs are NOT Working Effectively!!!
Full of Bad
Air

10. Is there a Fan that Works Right?
Yes, it’s TORNADO! Not kidding!

11. What’s the Difference?
Do other fans have similar function?
Regretfully, NOT to this degree. TORNADO is GLOBALLY UNIQUE.
Ventilation fan should have gone this way earlier.

12. What’s the Secret of the Magic?
If only you can understand the following formula…
Frankly, I don’t understand it, too!!!
The formula was developed by POSTECH and the relevant article
had won the Crosby Field Award by ASHRAE at Y2005

13. Show Me Some Breakdown!
Yes, of course, we don’t want to have many secrets!
TORNADO has a swirler fan inside.
It’s co-working with an axial fan or with a sirocco fan.

14. What’s the Merit for the Customer?
Above all, it works Right!
It removes bad air quickly with times of capture depth.
Please observe the following photos.

15. What other Merits?

16. Prove it ?
Why don’t you see the INTRODUCTION VIDEO of TORNADO.
It’s hard to make long explanation on all the merits here.
