Fan pre-wired with a 6.5ft long cable and grounded 3-prong plug. 2. Variable speed controller. 3. Speed controller cable (16ft long). 4. Installation Hardware (Screws and Anchors).How to adjust ECMF series fan speed?Each ECMF fan is supplied with a variable speed controller. Speed controller is attached to the fan via the supplied cable. When connected, supplied speed controller allows users to select any speed between 0-100% of output according to the preferred use/noise level. If the speed controller is disconnected, ECMF fan will automatically work at 100% output. Speed Controller connects to the fan via a 16 Ft wire, which is independent from the power cable. Will other Rheostat Speed Controllers work with ECMF fan?Speed controllers designed for AC motors, such as typical rheostat speed controllers, will not work with ECMF series fans. If you need a replacement of ECMF fan speed controllers please contact TerraBloom’s customer service. What are the requirements for the fan's operating environment?ECMF fan can be operated in the environments with temperatures between 15Β°F(-10Β°C) to 140Β°F (60Β°C) and humidity levels not exceeding 90%. ECMF series fans have IPX4 IP Rating. What type of ball bearing used in ECMF series fans?ECMF fans are built with heavy-duty dual ball bearings rated for up to 70,000 hours of operation.Can ECMF fans be used for boost airflow in heater ducts?ECMF can be installed in heating ducts with most modern home furnaces, however, it is important to ensure that the air temperature in the duct is not over 110 Β°F. Please note, fire places and fire-based heaters supply air at over 140Β°F, which will cause ECMF fan to trigger overheat safety switch and/or cause deformation of the impeller. Review: TLDR: 🌟🌟🌟🌟🌟 An inline fan that's a powerhouse in airflow, whisper-quiet, and energy-efficient - perfect for our indoor garden! πŸƒπŸ”‡ So, we've got this new inline fan for our 4x4 indoor garden, and it's an absolute beast at moving air! If you're setting one up, make sure your tent can handle the suction, or it'll be like shrink-wrapping your plants. We've linked it to a temp controller, keeping it at a cool 30% speed to get rid of the extra heat. Pros: Solid build quality - it's metal all over, except for the plastic impeller. Setup is super quick and hassle-free. Power use? Only 15w at the lowest and 25w at full blast. It's so quiet, you'll forget it's there. The airflow is surprisingly powerful for its size and energy draw. Attaching a 4in duct is no sweat. Snagged it at a fantastic price initially. Cons: It's locked to its own speed controller – no universal compatibility. Noticed a price jump after our purchase. Lacks auto adjustment features for humidity and temperature. Energy usage? It's a dream. Running this fan at 30%, with a small fan and a 135w light both on medium, we're only using about 90 watts. That's gentle on the seedlings and the electric bill. Crank it up for the growth phase, and it's still a lean 130 watts. Our electricity costs are laughing – this setup's costing us about $7 monthly. Haven't tried it with a filter yet, but we're eyeing up another fan and dual filters from the same maker for a future upgrade. In a nutshell: This inline fan is a star performer. Robust, ultra-quiet, and energy-conscious, it's a must-have for any indoor gardening aficionado. My one gripe? I'd love a feature to control the fan speed automatically based on environmental changes. But overall, it's a purchase I'd repeat without a second thought. Review: Amazing fan, so happy I found terrabloom. Ecm fans should be the current standard for all grow fans however this is not the case. Don't be fooled by other nice looking fans that have 60yr old fan technology inside. This paired with a good led grow light and you have a super efficient setup with infinite control over air speed instead of just a few speeds, and it will last longer, use less power and be more quiet. ## Features - TerraBloom EC duct fans are used in indoor grow facilities and vertical farms, heating and cooling transfer, commercial drying and air filtration applications.

But you need to make sure there won't be any hard particles going into the fan, as they can damage the blade and the motor. **Q: In a pets grooming salon dogs hair is flying all over the place when we blow dry the dogs. Can this unit be used to suck the dogs hair to a canister?** A: Hello, Unfortunately, this fan will not work well for your application. Pet hair will be getting stuck inside the unit and getting wrapped around the impeller and fan's rotor, which can potentially increase chances of overheating and malfunction. If you still decide to us it for this application you need to ensure that there is a filter placed before the fan which will catch all of the hair before it reaches fan's parts. This somewhat defeats the purpose, as you want the hair to go into a canister and not to be trapped on the filter surface before the hair reaches the fan. Hope this helps. Best regards, TerraBloom **Q: Does this fan have a dc motor? and is it pwm controlled?** A: This fan has a EC motor, which is a subtype of DC motors. Key difference is that it doesn't require a DC adapter since the conversion of electricity current happens inside the fan instead of DC adapter. The fan is controlled using Potentiometer technology and it yields exactly the same results as PWM. **Q: Is the shipping discreet?** A: Hi Daniel, You will need to select an option to gift wrap your order so that Amazon ships it in a additional box. We do not package or ship our fans directly to Amazon customers, it is done by Amazon staff from Amazon warehouses.

Long power and speed control cords. Fairly quiet too! Was my first exhaust fan so I really have nothing to compare it to. Had a defect and was still under the 2 year warranty. The sales rep I spoke to had my replacement unit sent out within a day of the inquiry. ## Frequently Bought Together - TerraBloom 4 Inch Inline Fan ECMF-100 - Quiet HVAC Grow Tent Fan with Digital Speed Controller- Premium Metal Casing 40-75% Energy Efficient EC Motor - For Large Spaces - TerraBloom 4" x 16" Carbon Filter for Grow Tent - 46mm Charcoal Carbon Air Filter - Maximize Airflow with 350 CFM - Premium Filter for Homes & Commercial Applications - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/449731647-terrabloom-ecmf-100-4-inch-inline-fan-with-digital-speed](https://www.desertcart.at/products/449731647-terrabloom-ecmf-100-4-inch-inline-fan-with-digital-speed) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-22*
