Hi everyone

I have a question: where do you usually install the static vac cleaner? Do you always use the kinetronics' bracket?
The company which I work for usually install it on the CNR's column, where the film exits from the platter. However, since the film has very low tension in that position, a static phenomen cause the film to be attracted from the chassis of the machine and it has caused too many film to be scratched.

I've temporarly removed the kinetronics but I'm searching a suitable place to install the machines. I think that I should install them AFTER the projector, where the film's tension is higher.

Where do you usually install these machines?

"Where do you usually install these machines?"

I usually install them on one hour photo printing/processing machines. That is what the device is actually intended for. They are pretty much usless on film and I always chuckle to myself when I'm in a booth that has them [Big Grin]

as they do absolutely no good tyring to clean and or neutralize static on a mile and a half or more of film.

It is one month that our kinetronics has been disconnected for the scratching problem explained. The film are more dirty, is a fact. I agree that these machines are not too efficient but they are not so useless.

Where do you install them on your photo printing machines? [Smile]

I've used these things before a long time ago. We usually just set them on the floor and thread the film through on its way back to the platter. Not really by choice, but that's the only logical place we could put it in relation to an outlet.

Like Mark said, they're useless in a booth. Sure, when you went to clean the filter out there was dust on it, but who knows if it was pulling the dust off the film or from the air? The brushes would get all dusty, too, since the air was sucked over them.

And it was worse at cleaning prints than PTR rollers. In fact, I think it made them more dirty! If semi-dusty film passes through very-dusty brushes, the film ends up cleaning the brushes. And it would take about 3 reels of running before they were covered. (Which leads me to believe it was cleaning the air more than cleaning the prints).

As for static control, I give this example: We had one of these running on our ELF platter for lobby trailers. The projector and platter were in an unfinished room for this setup, and despite the static vac, static problems were a nightmare. So I assume it does little or nothing in that department.

I can see how prints can get scratched easily on this thing, too, although I never had it happen.

Since many film make the brushes and the entire machine more dirty than other ones, I do not think that the dust you found on the brushes came from air! The brushes should be cleaned on each show, or at least each day, the static vac is useless if you clean it once a month!

On the floor means after the projector?

One theater I go to uses them all the time, on the floor between the bottom reel arm and platter on a homemade stand. I'll have to ask them if they have positive results.

Hopefully their results are neutral.
