Featuring smart WiFi app control, dynamic temperature and humidity programming, and a durable mixed flow design with PWM-controlled EC motor, it’s engineered for hydroponic grow rooms, HVAC upgrades, and odor exhaust.

By installing this fan, you can control humidity and CO2 levels to keep them stable while ensuring fresh air exchange in these spaces. It is built with IP65-level sealing that lets you place it in harsh environments, resisting moisture and spores. It also features a fan speed controller with 10 exact levels to produce your ideal airflow. This precision output is powered by the inline fan’s EC motor that utilizes PWM control to operate quietly and energy-efficiently. This product is a part of the UIS platform of grow devices and smart controllers, designed to unite with the AC Infinity app over WiFi to achieve your ideal environment.Precise Speed ControllerThe speed controller lets you set between ten precise fan speed levels to optimal noise and airflow levels in mushroom-growing environments. This exact airflow control is enabled by the cutting-edge EC motor that is precisely controlled using PWM (Pulse Width Modulation). This allows it to run smoothly at extremely low RPM speeds without generating motor noise. It also features backup memory that retains the last speed setting whenever power is cut off from the controller.Quiet and Energy Efficient DesignThis inline fan utilizes a mixed-flow design with a stator blade and dual hydrodynamic wind circles, enabling it to deliver airflow even in applications where air movement is restricted. In addition, it is built with dual ball bearings that have a 67,000-hour lifespan, allowing you to mount it in any direction. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Review: Quiet operation, great quality! - As usual never get disappointed with any product from AC Infinity. Quite operating, efficient. Works great with my AI Plus controller I have one for an exhaust fan the other one for fresh air intake fan Review: Top quality. - Had it for a month. Quiet, works great, no issues. I use it in my printer room to evacuate the air out of doors. I run it constantly, on low super-quiet settings when I am not printing, and on higher settings (a little louder) when actively printing bad stuff like ASA. The little noise it makes at high speed does not bother me because I leave the room anyway when I am printing the noxious stuff. It was obvious right out of the box that this was first-rate quality. I also bought the AC Infinity anti-backup valve and 12' of their 4 ply 4" flexible duct - also very high quality stuff. You will not be disappointed. ## Features - Specially designed for mushroom growing to quietly ventilate grow spaces and help control indoor climate levels. - IP65-rated to ensure performance in high-humidity spaces while resisting dust, debris, and moisture. - Includes a fan speed controller with precise 10-level control for exact airflow and CO2 buildup prevention. - EC motor with PWM control enables quiet and energy-efficient performance for consistent fresh air exchange. - Duct Size: 4" | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 212 CFM | Noise: 27 dBA | Bearings: Dual Ball - This product is equipped with a Type-G power plug and is compatible with the voltage commonly used in the United Kingdom. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DHYP3ZQY | | Air Flow Capacity | 212 Cubic Feet Per Minute | | Best Sellers Rank | 15,070 in DIY & Tools ( See Top 100 in DIY & Tools ) 47 in Household Ventilation Fans | | Brand | AC Infinity | | Brand Name | AC Infinity | | Collection Name | Specialty Fans | | Colour | Ip65 Speed Controller for H4 | | Control Method | Push Button | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 59 Reviews | | Electric Fan Design | Blower | | Electric fan design | Blower | | Finish Type | Powder Coated | | Included Components | Cord | | Indoor Outdoor Usage | Indoor | | Installation Type | Permanent Installation | | Is Product Cordless | No | | Item Dimensions D x W x H | 17.5D x 18.8W x 30.2H centimetres | | Item Weight | 2.09 Kilograms | | Manufacturer | AC Infinity | | Material | IP65 Speed Controller for H4 | | Model Name | AI-CLH4 | | Model Number | AI-CLH4 | | Motor Type | brushless | | Mounting Type | Fixed Mount | | Noise Level | 27 Decibels | | Number of Power Levels | 10 | | Number of Speeds | 10 | | Power Source | Corded Electric | | Power source | Corded Electric | | Product dimensions | 17.5D x 18.8W x 30.2H centimetres | | Recommended Uses For Product | Ventilating | | Room Type | Grow Tents | | Size | 4 inch | | Smart Home Compatibility | Smart Home Compatible | | Special Features | PWM Control, IP65 Rating | | Speed | 3000 RPM | | Standby Power Shutoff | High efficiency | | Style | Modern | | UPC | 819137024595 | | Unit Count | 1.0 count | | Voltage | 100 Volts | | Wattage | 18 watts | ## Product Details - **Brand:** AC Infinity - **Colour:** Pro Smart Controller - **Electric fan design:** Exhaust Fan - **Mounting type:** Wall Mount - **Power source:** Corded Electric - **Product dimensions:** 35.8D x 37.8W x 45H centimetres - **Recommended uses for product:** Air Circulation, Cooling, Exhausting - **Room type:** Kitchen - **Special feature:** Lightweight - **Style:** Industrial ## Images ![AC Infinity CLOUDLINE H4, Quiet 100mm Inline Duct Fan with Speed Controller Humidity Proof IP65-Rated Ventilation Exhaust Fan in Grow Tents Mushroom Fruiting Chambers Propagation Fungiculture, 4-Inch - Image 1](https://m.media-amazon.com/images/I/61JYcgjW+-L.jpg) ![AC Infinity CLOUDLINE H4, Quiet 100mm Inline Duct Fan with Speed Controller Humidity Proof IP65-Rated Ventilation Exhaust Fan in Grow Tents Mushroom Fruiting Chambers Propagation Fungiculture, 4-Inch - Image 2](https://m.media-amazon.com/images/I/71mJa+t2XML.jpg) ![AC Infinity CLOUDLINE H4, Quiet 100mm Inline Duct Fan with Speed Controller Humidity Proof IP65-Rated Ventilation Exhaust Fan in Grow Tents Mushroom Fruiting Chambers Propagation Fungiculture, 4-Inch - Image 3](https://m.media-amazon.com/images/I/61AzR5wi7RL.jpg) ![AC Infinity CLOUDLINE H4, Quiet 100mm Inline Duct Fan with Speed Controller Humidity Proof IP65-Rated Ventilation Exhaust Fan in Grow Tents Mushroom Fruiting Chambers Propagation Fungiculture, 4-Inch - Image 4](https://m.media-amazon.com/images/I/61HHA3hpY2L.jpg) ![AC Infinity CLOUDLINE H4, Quiet 100mm Inline Duct Fan with Speed Controller Humidity Proof IP65-Rated Ventilation Exhaust Fan in Grow Tents Mushroom Fruiting Chambers Propagation Fungiculture, 4-Inch - Image 5](https://m.media-amazon.com/images/I/71mdKRfbTCL.jpg) ## Available Options This product comes in different **Material Type, Style** options. ## Questions & Answers **Q: hello,i gonna use it in my grow room. do i really need the carbon filter while using this fan? if yes,can i use other brands carbon filter with it?** A: This machine just blows air in or out. The carbon filter get rid of smell. Two different things. Yes, you can use a different filter mix and match equipment. **Q: Is there no option to buy 2 fans and 1 controller?** A: No there is no option for buying 2 fans and 1 controller. If you do buy 2 fans I would get 2 s models and buy the controller separately. Saves a little bit of money and get the same results! **Q: I have read the reviews discussing the sizing issues with the inlet/outlet sizes being more 12.25 instead of 12. Has this issue been corrected?** A: If your trying to put that 12 inch flexible ducting you basically cant and just have to get aluminum tape. Its not that big of an issue though. With the tape it stays put. **Q: Can this fan be used to exhaust kitchen hoods (e.g. inline connected to a hood liner)?** A: I would not use such an expensive fan for a kitchen exhaust hood. The condensation and grease steam alone would gum it up and ruin it. They sell hood exhaust fans ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quiet operation, great quality! *by A***. on 16 April 2026* As usual never get disappointed with any product from AC Infinity.

This brand is great and super realizable. I've been using it for years. ## Frequently Bought Together - AC Infinity CLOUDLINE PRO T12, Quiet 12” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics - AC Infinity Flexible 12-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - EesTeck 2Pcs 12"(Diameter) Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps (289mm-311mm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/359453372-ac-infinity-cloudline-h4-quiet-100mm-inline-duct-fan-speed](https://www.desertcart.sc/products/359453372-ac-infinity-cloudline-h4-quiet-100mm-inline-duct-fan-speed) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-06-23*
