Covert Inline Fans offer high performance at a great value!


Air ventilation and circulation are essential to a healthy indoor harvest. Indoors, fresh air is one of the most overlooked factors contributing to a healthy garden and bountiful harvest.

Covert Inline Fans have all the necessary features to help keep your growing environment the way it's supposed to be. Our Inline Fans move lots of air quickly, quietly and efficiently!

These easy to install fans run very smooth due to a high quality molded impeller and durable ceramic coated metal housing. Thermally protected AC motors on these fans keep the electronic components cool and working the way they ought to be.

Covert Inline

Ventilation is a key component in indoor growth! Activated carbon filters are the best way to eliminate most VOCs (Volatile Organic Compounds), gasses, and odors from the air. Combined with a Covert Inline Fan in a ventilation system, 99.9% of noxious odors can be trapped inside the filter for good.

The size of your grow space dictates the size of the inline fan you should be using, each with its own CFM (Cubic Foot per Minute Rating.) CFM performance is also affected by the path and length of the ducting, even more so when using a carbon filter.

  • Quiet operation
  • Durable ceramic-coated metal housing
  • UL recognized components
  • High quality molded impeller
  • Thermally protected AC motor
  • Includes mounting brackets

How to hang your Covert Inline Fan

Once you have your Covert Inline Fan, you still need to ensure that it gets set up properly for maximum efficiency.

We've done our best to provide all the learning resources you may require in our Learning Center on how to properly install your Covert Carbon Filter.

This article - Grow Tent Setup Guide - goes over the entire process of setting up your grow tent. At Step 4 & Step 5 in this article we highlight different ventilation setup methods and what we prefer as well as every step required to properly install your filter.

Special Ventilation Setups

Air-Cooled Lighting

Air-cooled HID light fixtures have duct flanges you can easily connect a fan and ducting to. You can see an example setup in the diagram to the right. This setup pulls air through the carbon filter, then through the light fixture and finally out of the tent.

A great upgrade for air-cooled lighting is to use a separate in-line fan just for the lighting ventilation. This will make both your light cooling and your carbon filter work more efficiently.

Closed Loop CO2 Ventilation

When using CO2 producing equipment inside of a tent, you want to avoid allowing that CO2 to exhaust from the tent. Therefore you want a “closed loop” system which will filter the air of odors by recirculating the air in the tent through a fan and filter. It is recommended to utilize LED or aircooled lighting to avoid heat buildup in the tent. Air conditioning is recommended for larger tents using CO2

Using CO2 for a grow tent is a more advanced technique. If you want to leanrn more about CO2 for growing we have a great article here
