Sometimes you may doubt why should you use a filter, regulator, and lubricator? For that, we will give you an explanation about what are they, how will they work and where can you buy them for your system. So, have a look at this blog content to check the importance of FRLs (Filters, Regulators, and Lubricators).
FRLs are used in industrial compressed air systems for compressed air filtration, pressure reduction, and airstream lubrication. When air exits in a compressor or air leaving the compressor is warm, dirty and sometimes it may wet. These are caused to damage and shorten the downstream equipment life such as cylinders, valves, etc. So, before using this air system, it should be cleaned and lubricated. That’s why we have to use FRL in air compressor systems to keep it in optimal working condition.
What is Filter Regulator?
Now, we have a look at the filter regulator roles. An airline filter cleans the air that passes from the compressor. It cleans that compressed air by trapping solid particles, i.e., dust, dirt, and rust and separates liquid (water or oil). A regulator will control the air pressure and precision of liquids flow in compressed air systems.
Filters are installed in the airline upstream of regulators, lubricators, directional control valves, and air driven components like air motors, cylinders, and so on. Since airline filters eliminate substances from pneumatic systems, equipment damage is avoided and output losses are minimized by contaminant-related outages. Downtime at an industrial plant is expensive; it is always the consequence of a compressed air system that is polluted and poorly maintained.
Choosing the right filter size for any application will be done by determining the maximum allowable pressure drop caused by the filter. You have to determine the pressure drop by referring to the manufacturer's flow curves.
By releasing a controlled mist of oil into the compressed air, Lubricators minimize the internal friction in tools or equipment. To extend their functional life, most air engines, pumps, valves, air motors, and other air driven machinery need lubrication.
Apply lubrication to a system also "washes away" compressor oils in vapor form which travel through the system. The added mineral oils to the system avoid the build-up of synthetic compressor oil on system components. When lubricators are not used on a machine, a coalescing filter should be mounted to eliminate aerosols from the compressor oil.
Understanding the need for lubrication for the pneumatic part will decide the type of oil and the rate of the drip. The rate of decrease is how much oil is discharged downstream. Two types of lubricants exist, i.e., oil-fog and micro-fog. You have to choose a lubricator based on your application requirement.
Pressure regulators in compressed air systems reduce and control air pressure including rotary compressors Regulators are also sometimes referred to as PRVs (Pressure Reducing Valves).
Adequately a pressure regulator maintains a constant output pressure regardless of upstream pressure fluctuations and downstream flow requirements. During practice, changes in the primary pressure and flow are affected to a degree by the output pressure.
Generally, pressure regulators used in the following tools/ systems to control the pressure. They are air tools, blowguns, air gauging equipment, cylinders, bearings, motors, spraying devices, fluidic systems, air logic valves, aerosol lubrication systems, and other fluid power applications.
Two types of general-purpose regulators are available in the market. They are relieving and non-relieving. Relieving regulators will adjust from high pressure to low pressure. These can adjust to remove the excess downstream pressure, even in a dead-end situation.
Non-relieving regulators do not allow the downstream pressure to escape when similarly adjusted. Moreover, the trapped air also needs to release in another way for example through downstream valve operation. Downstream equipment flow and pressure specifications have to be determined to keep the regulator correctly for the application.
Where can you buy Filters, Regulators, and Lubricators?
You can purchase filters, regulators, and lubricators individually or as combined units of filter-regulator or filter-regulator-lubricator. If your equipment is self-lubricating, then you no need to install separate lubricator. Just install FR unit (Filter-Regulator) and if your system needs lubrication, then you have to buy an FRL unit.
Your FRL components type has been dependent on the equipment requirements. But, make sure every air system having at least one filter and one pressure regulator.
If you are looking to purchase these filters, regulators lubricators, get them from our PartsAPS store. We are supplying these components individually or as combined units. Therefore, visit our website and get in your required way.
We hope you got the required information on the filter regulator lubricator. Still, if you have any doubt to buy FRLs, you can clear it through our comments section. We supply OEM components at our PartsAPS store for your air systems to keep them in optimal condition.
