Quieter than I thought it would be and more powerful. Have a 12 x 13 utility room and removes air and odors very quickly. Have 25 foot horizontal 4" flex duct run to outside and the air coming out of vent is nice and strong. I usually run it at full on and it does run with a hum at lower speeds as with most all variable ones but noise is not a concern with my operation. Do not really know if the CFM is really 190 or if the wattage usage is really that low at 35 or so, but all in all I did my research and had lots of choices for what I wanted and so far glad with purchase and would recommend. Review: Nice quality and quiet - A little pricey but works well. Nice quality and quiet. No vibration. Strong air flow. The only con would be the price. I think it could be a bit cheaper. 4-8 inch ends sold separately would be a nice option. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01C6IJSB0 | | Air Flow Capacity | 190 Cubic Feet Per Minute | | Blade Material | Plastic | | Brand | Apollo Horticulture | | Brand Name | Apollo Horticulture | | Collection Name | Home | | Control Method | Touch | | Controller Type | Button Control | | Customer Reviews | 4.0 out of 5 stars 81 Reviews | | Electric Fan Design | Exhaust Fan | | Electric fan design | Exhaust Fan | | Finish Type | Powder Coated | | Form Factor | Inline Duct Fan | | Included Components | Cord | | Indoor Outdoor Usage | Indoor | | Is Product Cordless | No | | Item Dimensions D x W x H | 8"D x 7.6"W x 11.8"H | | Manufacturer | Apollo Horticulture | | Material | Plastic | | Model Name | 4" Inch 190 CFM Inline Duct Fan | | Model Number | 849344052111 | | Mounting Type | Inside Mount | | Number of Power Levels | 2 | | Number of Speeds | 2 | | Part Number | AH IF-P-4 | | Power Source | Corded Electric | | Product Dimensions | 8"D x 7.6"W x 11.8"H | | Recommended Uses For Product | Exhausting, Ventilating | | Specification Met | certified frustration-free | | Style | Modern | | UPC | 849344052111 | | Wattage | 35 watts | ## Images ![4" Inch 190 CFM Inline Duct Fan with Built in Variable Speed Controller for Ventilation - Image 1](https://m.media-amazon.com/images/I/71x-bd56+2L.jpg) ![4" Inch 190 CFM Inline Duct Fan with Built in Variable Speed Controller for Ventilation - Image 2](https://m.media-amazon.com/images/I/71J2kHxz7dL.jpg) ![4" Inch 190 CFM Inline Duct Fan with Built in Variable Speed Controller for Ventilation - Image 3](https://m.media-amazon.com/images/I/71pM67Yn16L.jpg) ![4" Inch 190 CFM Inline Duct Fan with Built in Variable Speed Controller for Ventilation - Image 4](https://m.media-amazon.com/images/I/71y+gAd5vaL.jpg) ![4" Inch 190 CFM Inline Duct Fan with Built in Variable Speed Controller for Ventilation - Image 5](https://m.media-amazon.com/images/I/61-45msVwrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good choice *by K***R on March 28, 2016* Very happy with it.
