It is a controversial issue that was discussed years ago and now with the push of some manufacturers it returns to the fore, since now with the glass fronts everyone wants to show their fans with A-RGB or RGB. Will a trend be created if some manufacturer launches a reverse flow model and succeeds? Why not invest in them with this boom of making everything show?
Reverse flow fans or also known as reverse fans are very unpopular in the West, but in Asia they are taking center stage and many manufacturers already have models very worked under this premise. Why don’t they succeed here?
A question of aesthetics or a question of performance?
It is not clear why more fans of this type are not added in the West, but the reality is that if what you are looking for is aesthetics right now they are the best option available without a doubt. Another thing is performance, since when air is sucked in, the nerves that hold the motor in the center create turbulence that involves channeling the air worse and generates much more decibels.
It is rumored that to alleviate these effects in terms of noise, speed, flow and static pressure, manufacturers are at a crossroads, since it seems the total cost in R&D to be able to make a model on a large scale is approximately double of a common fan.
If we add to this the low volume of sales in our continent, disaster is guaranteed. Also, no one is going to want to compete on costs against ordinary fans, who would pay almost double for a fan with worse characteristics and better aesthetics for negative pressure? There seems to be the question kit right now.
In addition, you have to modify the production volumes of other similar products, so you either increase the investment or reduce costs.
The problem of dust, a factor to consider in reverse flow fans
A reverse flow fan sucks the air with its dust particles towards its motor, so they would need an IP5X certificate to ensure that throughout their useful life they will not need maintenance, since they would be closed to prevent the rotor or bearing from being damaged. impregnate.
This raises the cost of the same, unless they are designed in magnetic levitation, where in this case we avoid the accumulation of dust, but we continue with the problem of costs. If a trend does not arrive that changes this, the reverse flow fans will be one more anecdote in our continent, while in Asia the mods with these fans begin to gain fame.
Here we simply turn the fans and settle for the vast majority of users, so as long as this trend continues they will not be able to take off, and it may not finish, although it is also true that first you have to tell the box manufacturers that do not restrict the entry of air into your chassis as impossible.
As we can see, it is not a simple matter as it seemed, since now R&D is frozen for daring products in the market and the market is pulling towards what already works: 12 cm and 14 cm ventis respectively.
