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: Great fan, ultra low noise level and lightweight design. well worth the purchase. - this little fan is awesome. previously used the vivosun 4in, but the last one i purchased was probably defective and far too loud. it eventually died. to their credit, vivosun did give me a prorated refund at about 90% of purchase price. that said, i’m soooo glad i spent the extra money to purchase this fan. the small size surprised me, and this review may change if the small, lightweight size can’t handle normal use. but, for now at least, two weeks in, its worked like a charm. the small size is misleading; the thing really moves air well. bonus is the power control; it comes with a cord that is long enough for pretty much anything. moreover, the noise level is neglible; the device is whisper quiet. finally, being able to adjust a full 100 percent is so intuitively right, i am surprised more fans with speed control don’t allow full control. very happy with the purchase. ## Features - Versatile Applications: TerraBloom EC inline fans are versatile, and used in indoor grow facilities, vertical farms, heating/cooling transfer, drying, air filtration, and more.

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.

The fan is quiet, even at max. I bought this fan to draw warm air from our main living level in the house which is heated by a woodstove in the winter, down into the basement. When we are heating with wood, our furnace doesn't run so our basement, therefore, the floor under our feet, gets very cold. To make this all happen I installed a vent at the top of a wall on our main living level near the wood stove and made a hole in the ceiling of the basement that corresponded to the proper chase in the wall. I secured rigid ducting to the bottom of the chase and hooked it up to the fan with some flexible ducting. I powered on the fan and walla! It was drawing warm air into the basement. I have only had it installed and operating for two days but the temperature of the basement which measures roughly 26x30x6.5 feet high has definitely improved. The floor under our feet is warmer as well. We can now comfortably wear socks and don't feel the need to wear slippers or moccasins to keep our feet warm n the floor. Yesterday, it was 28 degrees outside and the basement was a comfortable 58. Prior to installing the fan the basement would have been in the low 40 degree range. The fan is installed pretty much under our living room, about 3' under the floor and I can't hear it running, even on the max setting. A fantastic, economical, home improvement. ## 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.de/products/101848239-4-inline-fan-with-ec-motor-metal](https://www.desertcart.de/products/101848239-4-inline-fan-with-ec-motor-metal) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-30*
