AIR Line

Depends on how many cfm to the unit to be L'ed. Not too likely to be closed-circuited, though.

Compressor capacity is 5.41 Cu meter / Minute

Not usually sized by the compressor, unless there is a very unusual requirement that needs to be explained further.

CFM will be 190

Still not usually sized by the compressor, unless you want to lubricate all the leaks in the system, too.

tnx.

now am thinking to provide common frl.

If this air line is the same as you posted in Closed Circuit Air Line

12/31/2013 2:14 ARE you are probably going to have numerous problems with its operation.

We are having 200 CFM & 30 CFM air compressors & to give air at 6 bar pressure. We will have 36 user point from main header (Main header=2"; User line=1"; Over all main header length=500 meter with Closed circuit). Is this ok? (For our main header and pipe line layout for the system). Pls suggest.

Thanks

Any system such as that which you have described: length approx. 1,600ft or almost 1/3 of a mile; with 36 user points; 2" header with 1" user lines; is going to be extremely under-engineered for what you apparently want to get out of it.

If this is a loop system, the farthest user line will be approx. 800ft away from the oiler. That is about 700ft longer than the best micro-mist oiler can obtain. Just the condensation formed from the temperature reduction from the compressor to the user point is going to load this system with water after the one filter. This will obviously go through to the end of the user lines and drench the air using devices with condensation water.

If this is a straight line system, the last user line will be a 1/3 mile away (that's a minutes of driving at 20 mph). Although that is double the distance the problems you will encounter will be exponentially worse!

The premises for CR4 are that Original Posters, OP's, ask questions and answerers give answers as best they can for the questions. It is then up to the OP to decide which are the best answers. In this case several answerers have given suggestions that will work as an alternate to a system that clearly will not work. If you stick to your proposed system you will find in the end that it will not perform as anticipated. Suggest you contact a person knowledgeable about air systems and have them make modifications to your proposed system. If not, you will no doubt be wasting a lot of $$$!!!!

Good Luck, Old Salt

Hi Propel,

As Tornado says it is not usual to size the FRL to the compressor output.

A suitable sized FRL is normally located at each outlet and sized to it.

If you want to Filter/Regulate & Lubricate the whole air system then, I would fit a 11/2" Filter for a low pressure drop and good element life.

A 11/2" Pressure Regulator, and for the Lubrication a SMC Centralised Lubricator.

This unit is designed to lubricate whole systems by virtue of the very fine oil particle size it generates that can then travel long distances without dropping out of suspension in the air.

The down size of Centralised Lubrication is if you use Blow Guns or Spray Paint they get lubricated too.

Best regards,

John

tnx

GA's to 6 & 7. Follow their advice and you can't go far wrong.

Nothing more to add except the labour intensity of maintaining lubricators. One big one at source is quicker to check and fill than dozens of small units.
