I spray in aroom in wich I installed 2 exhaust fans and it sucs all the overspray efficiently but the problem is gets dust into the room , I work in a dusty environment . My question is : is it possible to create a positive pressure inside the room by adding intake fans more powerful than the exhaust fans and put a dust filter to these fans , the positive pressure would prevent dust from entering from other windows and doors .
Thanks

Yes it is but the right combination will take some trial and error work. I remember a high school spray booth that worked on the same principle. All of the doors and windows were also sealed. For safety reasons, a double on/off switch was located at the primary entry/exit point and the door opened into the booth. With the fan's running it was very difficult to open the door. If the door opens outward, it will smack you in the face when entering with the fans on.
*Thank you Steve for your information , I will certainly give it a try now , and fortunately My door to the room is sliding , so no smashing .JP Haggar
*Jean-PaulI spray my projects under simulair circumstances, I have to set my spray booth up in a dusty environment. The first thing I do is clean up my shop and set up my spray booth, it is very important that the fans being used are sparkles. I then open one window so I have a smooth flow of air going through my booth. once I have done all that I close off the back of my booth which has a filter in it. Now I'm ready to go at it and this set up has been successful for me.
