It features a CLOUDLINE LITE inline fan with speed controller for quiet and efficient performance.

Kit Duct Size: 4" | Fan Airflow: 165 CFM | Noise 29 dBA | Carbon Thickness: 38mm | Duct Length: 25ft Product Description Grow Tent Air Filtration System with all inline components needed to ventilate growing space. By assembling these essential parts, this package will help you quickly start your growth build and eliminate the guesswork of buying them individually. This inline fan kit features the CLOUDLINE LITE series fans with 10-speed controllers for powerful yet quiet performance. Combine with a carbon filter made from Australian Virgin Charcoal, it prevents odors from seeping through the glow tent. These two pieces are connected by flexible duct with four layers of protection to properly distribute airflow. Accessories include duct clamp, pre-filter cloth, rope clip hanger, and hanging strap to complete the installation. Inline Fan Growth Tent Ventilation Kit is headed by the CLOUDLINE LITE series in-line duct fan with a 10-speed fan controller. Utilizing stator blades and dual hydrodynamic windcircles, the CLOUDLINE LITE is a mixed-flow design that provides high performance airflow in most restricted applications. Motor box including fan impeller and blade can be removed from the mounted frame for easy cleaning and maintenance. This frame is made with a plastic mounting base that reduces noise caused by fan vibration, allowing you to mount it in any direction. Dual ball bearings give this inline fan a lifespan of 67,000 hours. Backed with IP-44 rating to prevent dust and liquid from splashing. Combine a 10-speed fan controller with this in-line fan to optimize airflow level and noise for many applications. The PWM control of the fan allows you to set the fan speed smoothly and operate at extreme low RPM without motor noise. In addition to this wired speed controller, the CLOUDLINE LITE is also compatible with the following controllers: B Series Temperature Controller T Series Temperature and Humidity Controller Controller 67 Controller 63 Carbon Filter, CLOUDLINE LITE In-Line Fan combined with a carbon filter to effectively block odors from the growth tent.

Use with included pre-filter and reversible flange (to invert the carbon bed) to further extend the life of the product. The sturdy construction is constructed with aluminum flange and galvanized steel mesh, allowing 100% air to pass through.

Review: Super easy set up, very impressed
Review: Device works great! Had a major odour issue in my apartment and this device has single handed made the odour go away. Even on the low 2 setting. It is pretty silent for the most part! I love that it comes with the cloth filter as well. Well worth the price.

## Questions & Answers

**Q: Will this be good for 48"X24"X60"  tent ?**
A: I use in a 4x4 tent works great.

**Q: For the manufacturer: I’d like this ventilation kit in the 4” size, but with the wifi version of the controller. Is that possible?**
A: Yes totally possible. I think its about 160ish with the remote as well. I opted for the speed controller bundle instead of the wifi controller and i regret not going with the better one. So good thinking on your part to go ahead for the better one.

**Q: Is there a warranty available on this it is not showing up when i addit to my cart ?**
A: All of AC infinity products, except consumables, are under a 2 year warranty. You just have to provide the order number, and confirm your address and AC infinity will replace or repair the defective product. Very easy replacement

**Q: Is the filter also inline with a 6" inlet and 6" outlet?**
A: The filter can be utilized either pulling air out, or pushing air in with the inline fan.
