Review

The AC Infinity CLOUDLINE T6 arrives as a much-needed energy efficient DC inline fan which doesn’t waste any power as it gives you power which is normally only expected from noisy AC motors. After all, 351 CFM airflow at just 32dBA is rather impressive. You hear the sound of moving air over the sound of the motor itself which is a welcomed change from most cheap competing inline fans.

Plug-and-play functionality is supplied with the fan unit, Thermostat-controller console, temperature sensor probe, power unit, and two duct clamps are supplied. You’ll be quite surprised by just how quiet this setup is, while the controls could not be easier to operate as well.

Here we’ll be taking you through a look at the Terrabloom 6″ Inline Fan with its powerful 395 CFM power and superior manufacturing. Despite the craftsmanship and high-end electronic design, TerraBloom has managed to keep the price quite low given the value.

Review

The TerraBloom 6’ Inline fan uses just 70 Watts of power to provide its 395 CFM air flow, operating at 2,400 RPM offering variable speed. Despite its considerable air flow, the unit runs cool and quiet. Its lightweight design comprised of heavy-duty black ABS plastic makes it ideal as an exhaust, intake, carbon filter, or light fixture cooling fan for your grow tent.

You can’t use it in high-temperature environments but very few grow tents ever exceed 140°F, the unit’s high-end air temperature limit. This inline fan incorporates many features with fantastic practical benefits. From a safety temperature sensor with a built-in cut-off to variable speed control that allows you to have the output, TerraBloom has thought of everything.

PROS

  • check
    Variable speed controller included
  • check
    High-quality construction
  • check
    Wiring which is easy to customize

4. Hydrofarm ACDF6 Active Air 400 CFM Inline Fan, 6-Inch, 6″

Hydrofarm is one of the oldest manufacturers of hydroponics equipment in the world. Their expansive collection gives you everything that you need to get your garden going no matter what you’re planting or how many.

From lighting kits to seed starting equipment, controllers, inline fans, duct fans and more, Hydrofarm is known for their cutting-edge designs and reliability. Here we’ll be showing you the Hydrofarm ACDF6 6-Inch Active Air fan and what makes it a long-lasting choice for anyone who isn’t bothered by aesthetics.

Review

Powered by a thermal-protected AC motor delivering 400CFM at 115 Watts, this active air inline duct fan gives greater value for its price. While not as striking as some fans, it does outshine most of the competition in terms of performance. It is heavier and sturdier than competing models and comes with an 8-foot pre-wired cord, a handy upgrade over the 5-foot standard.

You’ll also notice that its more compact than most other fans and the mountings are designed to allow the parallel or perpendicular connection, far easier than competitors. Another upside to its longevity is how the whole unit is sealed. There is no chance of dust or debris damaging your motor even after a year or two’s use.

The only possible pitfall is the noise level. Your fan runs somewhere between silent and noisy but isn’t typically loud enough to pose a problem once mounted.

PROS

  • check
    Powder coated finish
  • check
    Totally sealed motor
  • check
    Extended power cord
  • check
    High-quality construction
  • check
    Compact design

CONS

  • Louder than the average inline fan
  • Fairly standard appearance

5. iP Goplus Inline Duct Fan Quite Inline Duct Booster Hydroponics Exhaust Cooling Fan Blower

GoPlus is a manufacturer dedicated to efficiency. Their range of high-quality products gives you superior features and functionality, while products span everything from power tools to hydroponic peripherals.

The GoPlus 6-Inch Inline Duct Fan arrives at a surprisingly low price, especially considering its powerful 395 CFM rating.  Exceeding all expectations, this could be the best inline fan for a grow tent if you overlook the missing controller. Let us take you through a closer look at what makes this one of your top options.

Review

While the exact decibel rating is not listed, the manufacturer does indeed confirm that it runs at under 30 dB, making it considerably quieter than the great than the 32 dB average. It is actually so quiet that if you use a controller to lower the speed, you will end up wondering if it is actually on. This inline fan is so powerful that you can’t even question its performance when operating under a load of a filter.

The only downside to this fan is that despite being advertised with a variable controller, none is supplied. Nonetheless, even without the controller, the price is still reasonable. The unit also delivers zero vibration which is quite an achievement for inline fans of this size, and a clear reflection that it’ll most likely outlast any other similar product.

  • check
    Extremely efficient as just 70 Watts for 395 CFM
  • check
    High-quality ABS Plastic and long-lasting durability
  • check
    One of the quietest fans available
