"In my studio I use an air compressor to which is attached a Kinetronics
anti-static air gun.
The air compressor has filters for water and oil removal guaranteeing a
100% liquid-free air
flow. Although both expensive and space consuming this is the ideal studio
sensor cleaning
setup in my opinion. There's no limit as to how much air you can use, it
is totally free of static
electricity, the air flow is powerful and it does a top quality job.
I do understand that it is not a very common setup. I happened to have
all the components
prior to getting the camera. I use the compressor with my computerized
mat cutter . It is
made by Silent Air and makes no more noise than a refrigerator. I use the
Kinetronics anti-
static air gun to clean my transparencies and negatives prior to scanning
(dust sticks to
surfaces essentially through static electricity).
I recommend avoiding canned air as a means to clean your sensor at all
cost. Canned air
can contain liquids (water, lubricants or other) which may be sprayed onto
your sensor. I
heard that Visible Dust may release a portable, battery operated compressor
later this year to
replace canned air containers."
Anti-static brushes either depend on a radioactive element which needs renewing
regularly, or
they have to be plugged in.
I think using a static-charged brush may draw dust from negatives, but leave a
charge which
keeps collecting new dust...
