Customer Questions & Answers

Thinking of a custom application for a fan of this type. Are they pretty quiet or are they loud like a bathroom exhaust

Asked by: Legion
I have just installed a 5" and a 6", both in rigid galvanized heating duct. They worked extremely well in leveling out the temperature from one end of the house to the other. from over 3° C differential down to 0.2° The noise from the 5" was so great that I have had to shut it down. The 6" is not quite as bad but it is really noisy. Have contacted Suncourt to get their recommendation on a solution. The 6" is approx 15' from the register and the 5" was 6, screwed & taped. Will post a follow up once I get Suncourts recommendation.

Can this be installed in non metal duct work?

Asked by: Tank69
I installed mine in the insulated flexible style duct work. Was probably a little nicer because it isolated vibration.

Can I install this in the duct in basement for the upstairs air?

Asked by: Denny
I wouldn't it, it's just not powerful enough for a long run. Google search "Tjernlund M6" for a style of fans that have more power. I'm not recommend that brand, I just don't know what that style is called. They have a LOT of power and push a LOT of air.

How many cubic feet of air per minute does it move?

How many cubic feet of air per minute does it move?
Asked by: Hack
Hello, The fan moves 160 CFM free air and 250 max boosted. Free air is if the fan is plugged in and tested with no added pipes or elbows at zero static pressure. Max boosted is the most the fan can boost before becoming an impediment to the airflow. When placed in a duct with an existing airflow the fan boosts the existing airflow depending on the ducts CFM and any resistance to the airflow. For example, if you place the fan in a duct moving 300 cfm it would hamper that airflow. Thanks, Suncourt

Customer Reviews

Inductor 6 in. In-Line Duct Fan is rated 3.5 out of 5 by 55.
Rated 4 out of 5 by from HVAC 6" Fan I have lived in my house 5 yrs. My bedroom which is the last run from the furnace gets really cold with the door closed (during winter). I was walking through home depot and saw this item on the shelf and decided to give it a try. It is a night and day difference. This unit really helped and price meets the need. However, this unit does add noise when it is running. It is recommending to have this fan 6 to 10 ft from vent. I moved the fan about 20 ft from vent to cut down on noise which also made a big difference. Last tip is how to wire this fan into your furnace. I wired it directly to the furnace fan so it runs when ever the fan turns on. My furnace is 110V power and has EAC (electronic air cleaner) circuit. I don't have eac (instead just filter unit) so the fan can just be hooked to power and ground on these connections and the circuit get completed once the furnace fan kicks on turning on the HVAC fan.

Rated 1 out of 5 by from JUNK! Bought one at HD in Greece, NY and this thing barely moves. About as useless as a computer ... JUNK! Bought one at HD in Greece, NY and this thing barely moves. About as useless as a computer fan. Barely feel any air coming out of it. Also, you have to hard wire it and the pigtails are very short so you have to have the work box screwed directly to the fan. IF you really want to be serious google search the new style duct fans people are using. I got a "Tjernlund M6" (google that name to see the new style). The one I got is actually TOO much for one duct, so I put a ten dollar speed control switch on it, and with it turned all the way down it's perfect. I have to believe there's something in between the Suncourt junk and the M6 blower. Also that M6 blower has a long power cable on it with a regular plug, which is nice. Gives you more options. I did a double gang work box, one side with the speed control dial, and an outlet on the other side. Hope this helps someone!

Rated 5 out of 5 by from Works Perfectly My son was having a problem in his rented condo with the air conditioning not reaching his upstairs bedroom. Not being able to actually use the fan "in line" he rigged up a backward vent (shown without the cover) to pull the air to the second story. Worked absolutely beautifully, and it's portable.

Rated 5 out of 5 by from Fan quietly moves more air to distant rooms Product is as expected. Fairly easy to install by merely cutting a section from heat duct, sliding fan assembly into the space and installing with sheet metal screws. The joint is then wrapped with duct tape and insulation. Necessary to install an electrical handy box on the unit to accommodate the electrical connections to complete the project. I expect to purchase another.

Rated 3 out of 5 by from Had to replace these within about 2 years I purchased two of these as replacements for the two that I purchased about 2 years ago. The old ones had both failed. I replaced with the same units because I needed to restore the boost in the ducts and there were not other alternatives available. I hope these two last longer than their predecessors.

Rated 4 out of 5 by from Works Great! Wires Short This was easy to install and now my 2nd floor master, furthest from the furnance, now has about 3x the air flow. I installed a 6" on the supply and a 8" on the return to that room. The wires are really short, Hot/Neutral 6", GRD 4", so I had to solder some extra on them to read a jct box. Then wired it into the blower fan on the furnace. Super quiet too. -1 star due to short wires.

Rated 4 out of 5 by from Good for the price Easy to install. Lucky that I had a small section (about 2 ft.) of duct at the end of a long run. I put the fan at the end of the long run and then put the small section on the other end of the fan. So the fan ended up being about 2 ft from the register. Consequently I get quite a bit of air rush noise. Sounds like a low quality bathroom exhaust fan. It does work good - room was 63 F now is about 68 F.

Rated 1 out of 5 by from Poor I thought the first one I bought was broken. It moved that little of air. The second was the same, this thing might move 50CFM.
