water problem in compressor air.

by Hikam
(Sri Lanka)

Inside the compressor air duct water is there, it makes the problem in valve Operation, How can I avoid those situation?

____________________

Hikam, depending on where they are in the air line, compressed air filters are quite efficient at removing water from the compressed air stream.

All compressors generate water when they compress air into a tank or air main.

Please read the pages compressor water linked from the navigation bar to better understand the why of it, and then read the pages linked from Filters on the nav bar to learn what you can do about it.

If you need very dry air, check out the pages linked from Dryers on the site map page.


Cheers,

Manual drain valve for compressed air filter?

by William

I need the manual drain valve assembly for the polycarbonate drain bowl on my Speedaire 4Z027.

Do you have the drain valve or bowl with valve as unit?

Thank you!

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

If Speedaire can't help you (see the Speedaire page for a guide on how to contact your local source) then it might be easier just to replace the whole filter unit with one from a local source, and one from which you can get parts and replacements as necessary.

Look up the local source for air cylinders. As a fluid power distributor, I'm sure they can help you with a replacement filter unit. You do not have to use the same brand that came with your air compressor, just one that is similar in port size, and filter mesh size.

Cheers,

Bill

i want 2 know the best air filter nowadays.

Yashwanth, when you say you want the best filter, what does that mean? Lowest cost? Stainless steel housing? Smallest particle removal? What?

Please read the pages on this site about compressed air filters (linked from the nav bar) to better understand the details, and how to determine what filter you need for your compressed air.

Cheers,

Bill

Air / Water Separator for Compressor

by Robert

I am looking for an air/water seperator for my air compressor. It needs to maintain 120-130psi. I only run 3 main air lines off the compressor. 100gal compressor. can you help me?

Hello Robert:

A few things you need to consider.

An air/water separator, also known as an air line filter, doesn't maintain pressure. It's purpose is to use cyclonic action and a filter element to strip free water (liquid water) and particulates from the compressed air stream. That's it.

Most filters will have a delta P (pressure drop) across them of around 5 PSI. So, if you have an upstream pressure of 120 PSI, you'll get about 115 PSI out the other side of the filter. This is caused by the filter element and filter components restricting the air flow.

As the element gets plugged up, your pressure drop will increase, eventually to the point where you won't get enough air through the filter to do work.

Some manufacturers of compressed air filters offer an indicator of some sort on their filter housings to show when the element is getting plugged. Having a pressure gauge upstream, and another downstream of the air filter would do the same thing...tell you when the pressure drop is increasing, thus indicating that the element is getting plugged.

You indicate that you have a 100 gallon compressor. What you have is a 100 gallon tank. Except for reservoir capacity, the tank size tells me nothing about the compressor. You need to identify the horsepower of the motor. That can be converted (approximately) into CFM, and it's the CFM number you need to ensure that a new filter has the capacity for your air line.

All of the 3 air lines emanating from your compressor discharge outlet should be supplied through a main compressed air filter. Then, you will want to put another (smaller) air filter at the point of use for each air line. That will strip more free water (it condenses in the air lines) and any additional particulate from the compressed air before it gets to your tools or applications.

While it's not foolproof, particularly in high demand applications, since most general purpose filters provide around a 25-40 micron element, you can roughly size the filter by getting them with the port size being the same size as the supply line. For example, a 3/4" pipe air line should be fitted with a 3/4" NPT ported filter...and so on.

Much more information about air filters is found on the Filters page on this site.

Cheers,

Bill
