Frequently Asked Questions about FRLs

Coalescing Filter versus Particulate Filter?
Coalescing Filters remove aerosols--liquid droplets small enough to be suspended in air--while particulate filters are better at removing solid particles. Neither remove gaseous water (steam) or humidity; they can only remove liquids or solids from your air. If your problem is a humidity problem, you need an air dryer.

 

Do I need a Lubricator?
In most cases, the answer is no. Some components specifically require air line lubrication such as some air motors and other actuators, but most standard pneumatic automation products (including 99.9% of what Lydey Automation sells) does NOT require a lubricator. However, once you DO begin to lubricate an air circuit, you must CONTINUE to do so, at the risk of damaging the seals. So either don't ever lubricate hardware, or if you do, you have to continue to do so.

 

Soft-Start (or Slo-Start) Quick exhaust valves versus standard valves?
Both styles of quick-exhaust valves are designed to quickly exhaust a pneumatic circuit downstream upon loss of a solenoid signal. This valve also blocks upstream air. This valve is intended to provide additional safeguards from unwanted pressure in a machine cell. The slow-start feature is designed to slowly reintroduce pressure upon return of a solenoid signal, to prevent sudden movement of pneumatic devices. Sometimes it's important to have this feature, and sometimes it's not.

 

What if I want my FRL to flow the opposite direction of how the brackets are mounted?
the 650 series FRLs are highly flexible, and you can very easily configure the FRL units to flow right-to-left. Our preconfigured FRLs are stocked and configured to flow left-to-right, but simply moving the gauge on the regulator to the other side, and repositioning the mounting brackets/feet gets the job done.
