Silent Inline Fan Buying Guide 

You might be in a hurry to buy an inline fan but before that, consider the following factors;

Low Noise Level

If you are installing the fan in a grow room, you’ll need a quiet fan since you’ll be spending most of your time in the grow room. Noise levels are measured in dB, and the lower the value, the quieter it is.

Power 

Measured in CMF, this factor will help you know the amount of power you need for the grow room. It is commonly measured by determining the height, width, and length of the grow room.

You can test the inline fan and see how much time it exhausts the air from the room. If it does this within three minutes, then that is the ideal size of the inline fan. You can still get a quiet duct booster fan for more power.

Size

Size is vital when considering the amount of air you need in the room. Large-sized units will produce a lot of air to cool the room. The inline fans come in a variety of sizes, from 4 inches to 18 inches. Try to visualize everything in your tent before you settle on an inline fan.

Type 

There are three main types of inline fans that you can choose from. These include the; axial inline fans for small rooms, centrifugal inline fans for duct areas, and mix flow inline fans for both small and large rooms. Choose the right inline fan based on the types.

Ease of use

Check the guidelines and choose a model that will work efficiently regardless of your level of experience. A good manufacturer has a step-by-step guide to help you set it up and run the fan.

Price and warranty

Depending on the manufacturer, you will find varying prices of these inline fans. Surprisingly, you can get high-quality fans with impressive features selling affordably.

Check the features and choose your brand carefully. Be aware of overpriced items. The items we recommend here are affordable and efficient.
