You might be using less pressure or volume but I find the vacuum
necessary to keep the booth relatively clear of being in a virtual
dust cloud. I see much better with the vacuum running and it wasn't
that much of an additional expense. I also attached a vibrator motor
to the underside of the slope sheets to help recycling of the media.

Also get a shop vac to evacuate the air and keep the booth under

doesn't

have a connection for this, you can make one and bolt it over

an

existing vent on the booth. Note that this vent must also have a
filter to prevent all the grit from being sucked out into the

shop

vac. And for further protection, use one of those dust filters
available at hardware stores.

I haven't found any of this to be necessary, either, though

breathing

through a dust filter is obviously a good precaution. I have a

clear

plexiglass front on my sandblasting booth in which there are two

arm

holes with elastic cuffs cut from a cheap nylon jacket, so the

abrasive

powder can't escape from the booth. Seems a simpler way to

confine the

abrasive to the booth than what Mike is suggesting, but YMMV.
