Can anyone recomand a Dayton blower using a 6 inch duct that will work for me?
Well the two fans may still not be enough cfm to pull all the air out of the booth. The 6" duct is sufficient for a huge amount of air, and should be ample.
So long folks!
Bgrigg A higher rated fan, or two of the 200's should do it. 6" is plenty for the ducting. You can buy flexible duct hose that is much smoother on the inside than the typical dryer style.

Are you saying get another fan just like this one and run both of them though one 6 inch flexible hose that I already have? Would that work?
Ok I opened a window in the hallway and it didn't help so I guess I need a higher rated fan.
I got my fan from a large building supply company and it was one of the highest rated fans they had.
Any ideas where I can order a different fan that will fit this 6" duct work? I know I'll not find one in town so I'll have to order one.
Remember to get efficient airflow you also must provide a relief. If your house is air tight, it probably cannot push the air out the vent because there is insufficient air to replace it. Try opening a window just a crack in a nearby room to see if this helps any.

My booth is 29 X 18 X 15. I do use a 6 inch vent hose.
The fan itself is a wall fan rated at 200 CMF. It is a 8 inch fan but I could not find any 8 inch hose so I got a duct part that ran a 8inch opening into a 6 inch duct.
Should I get a higher rated fan or some different duct.
There is no way I can make the duct lower or the window higher so I have to either get a different fan or some more duct work.
I'll try to get my camera back tomorrow.
How big is your booth? Unless it is a downdraft and farly small it is probably underpowered.
Also that flexable vent hose is terrible, not only may it be too small (most are only 3-4") it has far more friction than regular duct. You can find charts showing what diameter duct you should be using, and how to calculate the "length" (the formula is based on length, curves add length, the flexable stuff adds 3-4x its actual length to the calculation).
My booth has a 485cfm fan on it and I'm using 6" duct when I actually hook it up (right now I just put it next to the garage door so it blows outside when I use it), anything smaller would seriously reduce the fans efficiency.
The airflow you are feeling is likely back pressure. Not knowing what your setup is, the culprit could be too large of a booth for too small of a fan. The fan cannot compensate for the air you are blowing into the space.
A common issue with home built booths. I know first hand! I'm trying to find a sufficient fan (on the cheap, I know where I can get fans for retail) to convert my home built booth into a down draft. While I'm proud of my booth and the work I did in building it, I sometimes wish I had just bitten the bullet and bought the Pace Peace Keeper.
Sorry but I don't have my camera here.
I do have a flipper on the outside and it opens very little when the fan is on, I took it off to see if air was coming outside enough and it is.
The back air I'm talking about doesn't feel like it's coming from outside. I feel the air when the fan is running.
Can you provide a picture of your setup? Is it air coming from the intake opening in the exhaust or just air from outside the booth being sucked past your work area that feels like it is back flowage from the fan?
When I am not using my exhaust system I put a plug in the end to keep the cold air from infiltrating the workshop. The little flapper valve on the outside vent fitting doesn't seal up all that well when the winds are howling outside.
I just build my first painting booth and it's hooked up to move the air outside the window. It has a 200 CMF rated motor. It has a flixable pipe that goes from the booth to the window. The way thinmgs are set up the morot on the booth is set up higher than the window creating a "S" in the filxable pipe. I moved the booth back from the window to strighten out the pipe as much as possible.
When I first tried it out air was going outside but I was also feeling air coming back into the booth. Is this normal?
I've tried to move the booth as far from the window as I could to try to straighten out the pipe thinking maybe it was forcing some of the air back to the booth. I've seen pictures on here with paint booth pipes that has more twists and turns than I do.
Anybody got any idea what could be wrong or what I could do?
