It's Frl On Purpose, Folks!
FRL is an acronym for Filter, Regulator and Lubricator, devices employed to situation the compressed air from a compressor just before it gets to your application be that by way of an air valve to air cylinders, powering air tools and so on. When referred to as in to troubleshoot a complaint from a client that their compressed air filter, regulator or lubricator wasnt functioning, the 1st response is to ask the symptoms. Typical complaints are, the regulator is not functioning, and its leaking oil, or my air filter fills up too speedily. Have you ever had these issues? The acronym FRL is placed in this order deliberately. These air treatment units, whether or not they are an assembly (mixture FR L) or a number of single elements - Filter Regulator Lubricator - installed in a row, must constantly be installed with the Filter initial, the Regulator subsequent, and the lubricator final. The filter must 'see' the air coming from the compressed air provide line initial, as its the defense against compressed air-borne water and particulates. If you consider about it, you would want the filter to remove contaminants and totally free water from the compressed air before that air gets to far more sensitive down-stream components, such as the regulator and the lubricator. The regulator is installed soon after the filter to make sure that the air receiving to the regulator is as clean as that type of compressed air filter will allow, thus increasing the life span and mean-time-amongst-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 utilized to dial-up the pressure. This is true, as extended as it really is understood that the pressure thats getting selected is at a level beneath the upstream supply pressure. You cannot use a regulator to enhance the pressure downstream larger than the provide stress upstream of that regulator. Compressors are generally cyclic, which means that the air pressure in the lines from them varies according to exactly where the stress 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 stress in the receiver up to the higher level set point, at which point the compressor will quit. This cycle repeats, sometimes quite quickly, based 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, ensuring that your application, if the regulator pressure is set at the appropriate level, will see a continuous, steady pressure. If the regulator is incorrectly installed, upstream from the filter instead of following it, not only is the regulator not protected from air-borne water and particulates, it will negatively affect the flow of air to the filter, decreasing its effectiveness. The lubricators purpose is to offer a steady, metered stream of the appropriate lubricant to the downstream application, be that an air tool, or an air valve / cylinder combination. The lubricator is installed final in the FRL series to guarantee that the lubricant has ready access to the elements desired to be lubricated although a lot of modern pneumatic circuits might not need to have a lubricator at all, what with the higher cycle variety lubricants that are frequently employed by air actuator manufacturer's. If the lubricator is incorrectly installed soon after the filter and just before the regulator, the lubricant flow will negatively impact the operation of the regulator. The regulator may be over lubricated to the point where it doesnt perform appropriately. This may possibly be the cause of the lubricators all gummed up and not functioning effectively complaint. Most compressed air regulators are relieving type, 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 just be intercepted by the filter, and not get downstream to the application at all. As a result the filter is filling up too speedily complaint. In the absence of the lubricator, the right installation if filter initial, then regulator. If the unit you have is a combined filter regulator, its internally plumbed to have the air filtered by way of the filter half before the compressed air gets to the regulator. Don't forget, its FRL on objective!
