Do you need to have hard duct to use it

Asked by: BB
Hello, You can install this fan with flex pipe. You will need to support the weight of the fan and use actual Duct Tape to seal the fan to the pipe. Thanks, Suncourt

When you say from 250 to 500 there a adjustment to get max out of the unit is need it as a boost to remove smoke

Asked by: Merrickwine
Hello, The 250 CFM refers to free air CFM. This is the amount of airflow the fan can move all by itself. Just powered with no restrictions or boosting of an existing airflow. The 500 CFM is the maximum the fan can flow before it becomes an impediment to the airstream. It will boost an existing airstream a certain percentage based on duct run distance, number of restrictions or impediments to the airflow and other factors. The DB208 you are looking at is a single speed 8" fan. There is no adjustment you can make to the fan to go from the 250 to 500 as you asked. Thanks, Sucnourt

Customer Reviews

Inductor 8 in. In-Line Duct Booster Fan is rated 3.4 out of 5 by 25.
Rated 5 out of 5 by from Booster Fan Nice and Quiet I bought this booster with an in line thermostat to control the humidity in our green house. This fan is designed for use in heating and cooling ducts but makes a nice adjunct in our green house to draw warm humid air to the outside. The fan was easy to connect up to the thermostat and is quiet in operation. Mounting was easy using a plexiglass panel to match the green house glass panels and was easily sealed using clear exterior silicone sealer. I added a vent screen to keep smal pests on the outside and that was it. My wife is happy which is what really matters. MP5SDA3

Rated 4 out of 5 by from worked as advertised I had to special order it because it wasn't in stock, but I received the item in a week or so. Very easy to install, if your duct is the right size. Mine wasn't, so I had to purchase a couple of reducers to make the fan fit, which it did. The wiring is easy to identify (hot, neutral, ground), but you will need to attach a box to the fan to put the wires in and attach them. You'll also need to add an on/off switch, unless you're going to wire the fan directly to an outlet box, The fan did make a difference with cold air output. The duct I put it in was for a room that is furthest from the central a/c unit, and wasn't getting suficient air (here in Texas, a/c is a MUST!). It did make a difference, but I couldn't tell you how much of a difference as far as lowering the temp. in that room. The fan can be a little noisy if you don't have sufficient insulation in your attic. That's a small price to pay for being able to cool a room who's temp. is probably in the 90's. Overall it's a good fan and works well. It's very affordable and fairly easy to install. I would recommend this unit to a friend or family member.

Rated 5 out of 5 by from These fans work great! Bought 2, they both move plenty of air. I'm glad I didnt read all the negative reviews

Rated 1 out of 5 by from Not Worth It This Booster Fan (or lack there of) is not worth it. It does not have enough blowing power to over come the static pressure in an air duct, you can look at the specs and it will show you that it does not have the power to do anything besides just sitting on your desk and blowing a nice stream or air on your face but once it is installed in your air duct, it does not do anything. If you are looking for a real In-Line Booster Fan, look for a Centrifugal fan, it will save you the time and effort of not having to redo the work.

Rated 5 out of 5 by from Duct Fan is Excellent I've read a number of posts on the web about duct fans saying they don't work but that isn't true. Fact is they do work! I installed this fan in the duct going to the office over our garage which was practically unusable during winter and now it is one of the warmer rooms in the house. I also changed about 11 feet of the 24 foot flex duct run to metal duct. At the register the air flow has doubled. The fan is about 20 feet from the register. The office is now at 70 degrees an increase of 5 degrees. Our thermostat is in the living room set at 68. The fan has made a huge difference!

Rated 4 out of 5 by from 4.5 stars - not Perfect but well worth it! I installed this inline such that when the AC is running it boosts upstairs cooling. The exhaust has one connected to a separate on/off switch. For ~$40 it is WELL worth it! **I had to use a 24VAC relay to control the supply fan. Sold seperately probably at RdShk**

Rated 4 out of 5 by from This product is good value and does the job it is intended for I purchased the booster to replace one that was in our heating system when we bought the house 10 years ago and likely was older than that. It had become very noisy. I had to modify the new one, because the section of 8-inch duct that the blower is in had its compressed end at the wrong end to fit the right way into the heating duct. The booster would have blown air back toward the furnace. This involved drilling out four rivets, turning the motor bracket the other way, and re-riveting with a pop riveter. Sheet metal screws or self-tapping screws also would have worked. I also had to drill a new hole for the power leads. In retrospect, I probably could have removed the motor from the bracket and installed it facing the other direction, but it then would no longer have been in the center of its section of duct. This would have avoided the rivet work, but a new hole for the power leads would still have been needed. The installation instructions do not cover such a modification, so the manufacturer must be assuming all heating ducts are installed the same way -- obviously not the case in our house. I expected the motor would be totally silent; it is audible, but not annoyingly so like the old one. Perhaps rubber insulating cushions where the motor attaches to the bracket would make it quieter. The power leads are short; the junction box would have to be almost touching the duct in order for them to reach. An extra 4 inches of wire would be helpful.
