Dryer Booster Fan System

I could not agree with you more. The performance graph for this fan has gone missing from the Home Depot website. I apologize for that. Thank You for pointing this out as we have already started the process of getting it back up. But since I have it in front of me let me answer your question. The performance of all fans is illustrated on a graph called a performance curve. One axis you have the output in CFM and on the other the resistance which we call pressure drop. The curve illustrates fan performance across its operating range. At one end of this curve, where you have no resistance, the unit will move 185 Cubic Feet Per Minute. This is the figure that most manufacturers promote when describing a fan. But it is a little deceiving as you will always have duct work and the drop off in performance created by the resulting pressure drop is different with every fan. With some fans the performance quickly drops off with only slight resistance. By calculating the pressure drop created by the duct work and consulting the curve you can determine exactly what you will get in your application. With resistance equal to 1.2 Inches of Water Column the curve shows you will get 80 CFM and at 2 inches of water column the flow of air will stop. In this scenario the total force of the fan is absorbed by the friction of the duct work.

Whether a dryer uses gas or electric heating elements the exhaust temperature should be the same. The energy source should not matter.

Yes. Built into the control box that comes attached to the fan is a pressure switch. When the dryer comes on the movement of air through the duct activates the switch which causes the fan to come on and add supplemental force. When the dryer completes its cycle, the fan shuts off in reverse order.

If you expand that section, you will find PDFs of the product documents which offer further details.

If from a desktop computer, you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. Locating the unit is discussed in section 3.1.2 on page 3. Where it states following. To prevent damage to the dryer or to the product, do not install the DBF 110, #95900 within 5 linear feet (1.5 linear meters) or further than 40 linear feet (12 linear meters) from the dryer outlet. AND If the product is installed less than 15 feet (4.6 meters) from the dryer outlet, install a secondary lint trap between the dryer and the product.

Opening the instructions you will find wiring discussed on page 6. Electrical Code varies by state, municipality and inspector. For definitive answer to how it should be wired in your home you would need to speak to a local qualified licensed professional. They should be able to tell you if this unit can be installed with a cord into an outlet in your application. I have always hard wired them to a box with a switch so that power can be shut off if service is required.

It does not come with a wire for hard wiring. On the side of the unit is a wiring box. The electrician would bring the power supply into that box and attach the wires to the terminal block.

Fantech strongly recommends using rigid duct work on dryer vents because the smother surface is less likely to sustain lint build up. Flex duct has an uneven surface that creates resistance and allows for lint build up. There fore you may end up having to clean the line more frequently. However so long as the flex duct is code approved for the application it can be used.
