FRL is an acronym for Filter, Regulator and Lubricator, devices employed to condition the compressed air from a compressor prior to it gets to your application be that through an air valve to air cylinders, powering air tools and so on.

When called in to troubleshoot a complaint from a client that their compressed air filter, regulator or lubricator wasnt operating, the initial response is to ask the signs and symptoms. Prevalent complaints are, the regulator is not operating, and its leaking oil, or my air filter fills up as well quickly. Have you ever had these issues?

The acronym FRL is placed in this order deliberately.

These air therapy units, whether or not they are an assembly (mixture FR + L) or a number of single components - Filter + Regulator + Lubricator - installed in a row, ought to always be installed with the Filter 1st, the Regulator next, and the lubricator final.

The filter need to 'see' the air coming from the compressed air provide line very first, as its the defense against compressed air-borne water and particulates. If you believe about it, you would want the filter to take away contaminants and free of charge water from the compressed air just before that air gets to more sensitive down-stream elements, like the regulator and the lubricator.

The regulator is installed right after the filter to make sure that the air obtaining to the regulator is as clean as that kind of compressed air filter will permit, as a result increasing the life span and imply-time-among-failures for the regulator.

The regulators objective is to regulate a lower pressure to the downstream application. Some people are of the opinion that the regulator can be used to dial-up the pressure. This is accurate, as long as it really is understood that the pressure thats being chosen is at a level under the upstream provide pressure. You can't use a regulator to enhance the pressure downstream greater than the supply pressure upstream of that regulator.

Compressors are typically cyclic, meaning that the air pressure in the lines from them varies according to where the pressure is in the compressor receiver. When the air pressure in the compressor receiver falls to the low level set point, the compressor will kick in, and bring the pressure in the receiver up to the high level set point, at which point the compressor will quit. This cycle repeats, sometimes quite swiftly, dependent on the compressed air demand in the shop. A regulator will dampen the pressure swings from the system as the compressor kicks on and off, making certain that your application, if the regulator pressure is set at the correct level, will see a continual, steady pressure.

If the regulator is incorrectly installed, upstream from the filter rather of right after it, not only is the regulator not protected from air-borne water and particulates, it will negatively have an effect on the flow of air to the filter, decreasing its effectiveness.

The lubricators goal is to supply a steady, metered stream of the appropriate lubricant to the downstream application, be that an air tool, or an air valve / cylinder mixture.

The lubricator is installed final in the FRL series to ensure that the lubricant has prepared access to the components desired to be lubricated even though numerous present day pneumatic circuits might not need a lubricator at all, what with the high cycle variety lubricants that are frequently used by air actuator manufacturer's.

If the lubricator is incorrectly installed right after the filter and ahead of the regulator, the lubricant flow will negatively have an effect on the operation of the regulator. The regulator could be more than lubricated to the point exactly where it doesnt function effectively. This may possibly be the lead to of the lubricators all gummed up and not operating properly complaint. Most compressed air regulators are relieving variety, and if the lubricator is "feeding" lubricant to the regulator, lubricant will wick from the relieving port, therefore the "regulator's leaking oil" complaint.

If the lubricator is installed upstream from the filter and the regulator, the lubricant stream from the lubricator will simply be intercepted by the filter, and not get downstream to the application at all. Thus the filter is filling up also speedily complaint.

In the absence of the lubricator, the proper installation if filter very first, then regulator.

If the unit you have is a combined filter regulator, its internally plumbed to have the air filtered by means of the filter half just before the compressed air gets to the regulator.
