Filter for cleaning photographic slides

by Mike
(Marlboro)

I have a need for using compressed air to remove dust on 35mm slides. What size/type filter should I use or should I just stick to cans of "Dust Off"? BTW I have a Porta Cable pancake (oiless) compressor. Thank you.

Hey Mike. Nice to hear from you.

It were me, I'd be sure to have a general purpose filter upstream from my blowgun and, I'd be darn sure to have a regulator in the line to lower the pressure through the blowgun as low as possible and still blow off the dust.

In the short bursts you'll need, you shouldn't have to install any kind of dryer, but watch your slides if you use a lot of air, as you may get the odd water spot, particularly if it's humid.

Start dusting at a couple of PSI and crank the regulator up slowly until you are getting the blow-off you need.

If water problems develop, install a small in-line desiccant dryer.

Be aware that moving air can create a static charge on the object over which it is flowing.

Cheers, and thank you both for visiting, and for writing in.

Need an air filter

by Mark

Hello Mark. The only thing I sell from this website is information, and most of that is free for the taking.

I get tons of requests from folks asking me to call them and help them out. I can't possibly respond to all the requests for phone calls, so I don't call anyone back. Sorry.

Look up the local source for air cylinders. As a fluid power distributor, not only will they supply cylinders, but they will supply FRL units as well, and I'm sure they can help you with a replacement filter unit.

Cheers,

Bill

Can anyone supply me with information on how to remove sulphur oxides (SO2 ) from our
compressor inlet air supply in polluted environment?

Is there a special filter that's available?

Filtering Sulphur from Compressor Intake
by: Bill - Publisher

Rajesh:

This is a tough one, and certainly falls outside (way, way outside) my "expertise".

I'm told that Sulphur oxide emissions to air mainly come from the combustion of fossil fuels containing variable proportions of sulphur (0.5% to 3% for oil and 0.5% to 10% for coal), and a wet process using a gas/liquid reaction can remove up to 95% of the emissions.

However, you'll really have to talk to a company that manufactures scrubbers to come up with unit that will allow you pull free air through it to the compressor intake, and in the process strip the unwanted emissions from the air.

One company that I know of that does that sort of work on an international level is Fabricated Plastics (www.fabricatedplastics.com). View their site, and if you feel that they can provide a solution, contact them directly.

I invite any visitors that have any knowledge about this to post your comments too.

Cheers,

Bill

water seperator

I am new to the air compressor game, and a very infrequent user at that.

It has a 24 gallon tank.

My question is in regards to whether or not I need to add a water seperator to my compressor. When I do use it, I drain the water afterwards from the valve on the bottom of the tank. Will I still need to add a seperator, or is this enough? If I do need to add a seperator, where is the best place to do this on the tank? Thanks for the help.

All very good questions, friend.

In my opinion, if you are using compressed air regularly, you will want to add water separators (compressed air filters) at a number of locations in the air circuit.

Much information is written on this site about just these issues, and I would certainly recommend that you read all the pages relating to compressor water (see site map page), plumbing of air lines, and water treatment.

The answers to all of your questions are already there, in detail.

Cheers,

Bill
