Hello everybody

I have found a old ULF camera whith suction film or paper holder in. But I am not the pump. I know I can use a vacuum cleaner, but it makes too much noise. I am looking for a pump that could be used. The format is 24X24 "and I would like to suck fiber paper or otho film.
Could you indicated me a model of pump?
Many thanks
Phil

Put the vacuum cleaner in another room and pipe the vacuum to where you need it. Vacuum cleaners are noisy, but cheap, and move a lot of air. Good luck.

A vacuum back requires remarkably little volume. Shop around.

Thanks for reply
I know the problems with a vacuum cleaner, and it is not evident to used it. (noise), it is true it' s more cheaper than a pump.
I would like find one. Could give me a brand of pump for that? Do you know where I can find one?

Look for something like a Robinair high vacuum pump for evacuating ac systems. It may even need a bleed valve to reduce the vacuum because it will pull 28-29hg which is about max you can get without special equipment. You can often find them used pretty cheap.
