Actually.......no. If you built a back wall with say 4 filters in the back panel then it would have a rather large surface area. The 1000cfm fan measures maybe 12" diameter, so the pull it would have would be great enough to pull the powder in towards the filters, but not great enough to have suck it completely by the part. You can use a dimmer switch to control the fan speed if need be, but it would be better to buy the larger fan and slow it down. You can't speed up a smaller fan.
