Great product and the quality was good. The price was just right. would purchase from the seller again

Great fan surpassed what I was looking for thank you

This fan works well and does its job well. Though its rather loud on its highest setting, I rarely need to push it that high.

I was using this to replace a 16” surface mounted fan on a specialty waste oil heater. The original fan was very loud for the workspace, so I built a plenum and ductwork and relocated the inlet side to another room with this fan being the source. I was hoping for quieter operation and better airflow for a given wattage, and in that it was a success. I measured the wattage of this 10” fan on all of its ten speeds:1 6W2 11W3 22W4 36W5 53W6 75W7 102w8 148w9 192W10 249W

I liked the features of this fan, including the speed control. It's a superior design because it has rotor and stator blades inside the housing. This type of fan is quieter more efficient than a simple fan blade design, and it's similar to the ones we used on US Navy submarines. That should tell you they are quiet and move a lot of air. The housing on either end can be split from the center motorized fan module by removing a clamp. This allows for cleaning the fan or swapping out a bad motor. In theory, this feature simplifies a booster fan repair because once duct joints are assembled, especially in an HVAC system, they are difficult take them apart. I say "in theory" because you need to know how to use the clamps that hold the motor section to the inlet and outlet section. Loosen the screw until about 1/4 in of thread is showing below the nut. DO NOT unscrew the nut all the way. Leave the clamp assembled but loose. You sort of pop the clamp off, and when reassembling, you pop it back in place. It is similar to putting a bicycle tire on the rim. Note that the fan includes a second set of clamps, but these are used to attach existing ducting to the body of the fan.My application for this Inline Duct Fan was for HVAC ducts. Two legs of my system were fairly long and ducts were undersized. Installation was fairly simple. The set of steel duct clamps provided in the kit came in handy. I added mastic tape around the joint and activated the adhesive with hand pressure. Once attached, it's hard to take apart so I took my time to make a good seal and a mechanically strong joint. I needed to suspend my fan, so think about the mounting method before you get started. You could also use the metal bracket attached to the housing.I powered the fan with a relay circuit that energizes the booster fan only when the main HVAC unit comes on. I watched a YouTube video of someone else solving this requirement. I bought the relay on Amazon: RIBU1C Pilot Relay and use it to control both. At most, both fans draw 2 amps or less, well within the spec for this relay. After I finished the electrical work, I used the fan unit's 8 speed settings to adjust airflow and balance the HVAC system. I balanced the HVAC airflow by varying the speed on the fans. I have installed fans on two long duct runs. At fan speed 8 (max), the unit gets noticeably noisy, but it's also pushing a lot of air. You probably won't need top speed. In my system, setting the fan speeds at 3 to 5 balances the airflow. At this setting, the fan is very quiet and still pushes a lot of air. Airflow adjustments can be made with the speed controller. The rooms connected to the system are now much more comfortable. I'm ready for a hot summer!
