This company really cares about quality products. Very quiet at speeds of 1-5, only small levels of noise at 6-10. My bathroom exhaust fan is louder than this though this is moving 4 or 5 times the air with a filter. Would def buy again. Thank you. Review: Excellent odor control!! - We use our 4ā€ cloud line system for our rodent room (we breed rodents as feeders for our reptiles) and the ammonia can build up to toxic levels quite quickly if not exhausted out. The 4ā€ is super quiet and we use it in a space equivalent to approximately 200 SqFt and vent the exhaust outside. It works exceptionally well for our modest collection of 40 breeders (rotated cycles) and anywhere from 50 to 300 grow-outs at any given time. The more grow-outs, the more critical the filter becomes necessary. It works so well, we normally only need to run it for half of the day unless we are sitting on a ton of grow-outs; in which case, we run it at max power all day. ## Features - An air filtration kit with everything you need to cool, ventilate, and control odors in your grow space. - Features the CLOUDLINE inline fan with speed controller, delivering silent and efficient performance. - Carbon filter with prefilter cloth uses 1200+ IAV activated charcoal for high efficacy odor blocking. - Four-layer flexible ducting connects the inline fan and filter to your grow tent to direct airflow. - Kit Duct Size: 4ā€ | Fan Airflow: 165 CFM | Noise 29 dBA | Carbon Thickness: 38 mm | Ducting Length: 25 ft. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NXKGK89 | | Best Sellers Rank | #15,443 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #26 in Greenhouse Ventilation Equipment | | Brand | AC Infinity | | Brand Name | AC Infinity | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 304 Reviews | | Frame Material | Metal | | Inner Material | Aluminum | | Item Dimensions L x W x H | 11.89"L x 7.48"W x 6.93"H | | Item Weight | 7.88 kg | | Light Source Wattage | 34 watts | | Manufacturer | AC Infinity | | Manufacturer Part Number | AC-FKS4 | | Model Number | AC-FKS4 | | Number of Items | 1 | | Outer Material | Dual PVC thermoplastic | | Product Dimensions | 11.89"L x 7.48"W x 6.93"H | | UPC | 819137022065 | ## Product Details - **Brand:** AC Infinity - **Color:** Black - **Frame Material:** Metal - **Item Weight:** 7.88 kg - **Product Dimensions:** 11.89"L x 7.48"W x 6.93"H ## Images ![AC Infinity Air Filtration Kit 4ā€ with Speed Controller | Inline Fan and Carbon Filter Combo, Cooling and Ventilation System for Grow Tents, Hydroponics, Indoor Gardening - Image 1](https://m.media-amazon.com/images/I/61Fwcw4OBQL.jpg) ## Available Options This product comes in different **Size** options. ## 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: Iā€™d like this ventilation kit in the 4ā€ 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. ## Customer Reviews ### ā­ā­ā­ā­ā­ Awesome *by M***T on April 22, 2026* Awesome, superb quality.
