ECO Farm 10 IN-LINE FANS VS HURRICANE Inline Duct Fan
While you grow plants in a grow tent, then several things come to mind. To make sure the plants grow enough and get enough air and temperature from the environment, you need good ventilation. For that, you have to install the best inline duct fan to grow a tent in your small nursery.
If the airflow is not adequate in the tent, then the plants will absorb more CO2. Humidity will make the plants ill. So, to avoid that, installing a duct fan is a great solution. Here we will discuss the best duct fan that you can install in your grow tent. Everything from motor power to CFM, we will let you briefly detail each product you can choose.
How quiet can an inline fan be?
It is a really good question because you need to know exactly how much noise a fan would produce in order to select one of the options available in the market. Luckily, most of the manufacturers provide the details of the noise their device can produce at maximum.
It is scaled in dBA and we have mentioned it alongside every option we have discussed so far. Remember, this is the maximum noise a device would produce when it is working at full capacity. It means that you can encounter less noise as well depending on the environment and the speed of the fan. All the fans we have mentioned are quiet and they produce a negligible amount of noise.
Features:
The ECO Farm inline fan has a heavy-hitting blower with a fan speed of 2750 RPM for an airflow of 810 CFM. Moves air through your target location efficiently for optimal ventilation. A powerful fan puts out only a 60 dB noise level. Tight, precise construction eliminates rattling and reduces wear and tear to give the element a long life. The aerodynamically designed centrifugal impeller of this unit delivers strong airflow with a disproportionately low sound profile. Ideal for cooling lighting fixtures or controlling hot and humid conditions in grow tents/rooms.
HURRICANE Inline Duct Fan for Grow Room
Features:
With a diameter of 10 inches and a power rating of 780 CFM, this is another product that is ideal for large-scale applications. This is ideal if you are a commercial grower, not a hobbyist. In-line fans are made of powder-coated steel. With this, you can be sure that it will be impressive in terms of durability. Mounting brackets and comprehensive instructions are already included in the kit. With the latter, installation can be done in minutes. Finally, the manufacturer offers a five-year warranty, which should already reassure you that the quality will be hard to beat.
How to Pick the Best Inline Fans
When selecting a quiet inline duct fan, you need to think about more than just noise level. Be sure to consider these factors:
CFM Rating
CFM stands for Cubic Feet per Minute and is a rating of how much air the fan moves. As this is a fan’s main job, it’s obviously an important factor.
CFM does relate to room size, but this is less important when thinking about applications like a grow tent. Most inline duct fans will be more than enough for a small tent. But, as I mentioned above, you want to add an extra 25% onto your needs.
To work out the right CFM, you first need to know the volume of your space in cubic feet. This is the length times width times height. For example, a tent that’s 4’ x 3’ x 6’ has a volume of 72 cubic feet. You’d need an inline fan with a CFM rating of at least 72.
Always consider choosing a model 20% above your baseline need. It will account for the loss of pressure induced by the turns and length of your ducting.
If you have grow room accessories like a silencer or a carbon filter, it will reduce the inline fan’s performance. I discuss this in more detail in the final section of this article.
Generally, larger inline fans will have a higher CFM rating. Most manufacturers will state it, so check this before buying.
Variable Speed
Variable speed is useful for quiet inline fans because it impacts the noise level. Fans operating at a higher RPM will produce more noise than at a lower speed.
Speed is also tied to CFM, as faster speeds usually mean more airflow, although this also relates to the fan’s size.
If the inline fan’s CFM is right for your needs, you don’t need variable speed. But, opting for a variable-speed fan with a higher CFM allows you to operate it at lower speeds. This means less noise, even with quiet models.
The controller might be a remote or a dial. A dial will give you greater flexibility than preset speeds, but either works fine.
Noise Level
A typical domestic inline fan can have an operating noise level of up to 70dB. This is the equivalent of a noisy restaurant. So, it’s not painfully loud but would be annoying if you’re dealing with it constantly.
Acceptable noise levels for the quietest inline fans are subjective. But, I’d recommend looking for ones around the 35–45dB level. This is around the same level as a refrigerator, so shouldn’t be too distracting.
The important things to look out for when picking a quiet model are:
Die-cast or unibody housing — reduces vibration.
Lubricated ball bearings.
Low noise level ratings on the product specification
High quality parts (metal fan blades, EM/brushless motor). This will usually be reflected in the price.
Any manufacturer touting their fan as quiet will state the decibel level. Look out for this and compare it against a chart of common sounds for a better understanding.
Installation Compatibility
When installing a quiet inline fan, you should ensure it matches the other equipment you have. It isn’t a massive problem if you’re buying ducting but can be if you’re integrating it into an existing setup.
Silent inline fans come in a few sizes: 4”, 6”, or 8”. You can get 10” and 12” too, but these are less common.
The fan’s diameter is tied to factors like CFM rating, noise level, and to a lesser extent energy consumption.
Whatever size you pick, just make sure everything else matches it. For example, ducting and carbon filters must be the same diameter. If they’re not, you’ll have a difficult job of making them fit.
When setting up a grow tent, it makes sense to buy a complete kit if you can find one. It simply takes away the problems of finding compatible hardware.
Temperature and Humidity Control
These extras aren’t that important for somewhere like a kitchen but might be helpful in a bathroom. Generally, you’ll want temperature and humidity control on a grow room exhaust fan.
They’ll obviously increase energy consumption but should have little or no impact on noise level. If choosing a model with these extras, make sure it comes with clear control modules. Digital is best if you need high accuracy.
Conclusion
In conclusion, the inline fans are common with different specifications for the roles. We spent time researching, and out of the many options, narrowed down to the top rated quietest inline fans on the market.
They’re both very simple to set up and extremely effective for even difficult tasks.
