Filter, regulator and lubricator unit with gauge (FRL)
An FRL unit is the simplest way to look after your pneumatic tools: in a single assembly it filters out moisture from the receiver air, regulates the outlet pressure and lubricates the air going to the tool.
Two sizes: 1/4" M-F with a flow rate of 240 l/min (14.4 m³/h) and up to 12 bar, or 3/8" and 1/2" M-F with 450 l/min and up to 16 bar. Both handle up to 60 °C and include a gauge.
✅ Key benefits
Three in one: filter, regulator and lubricator assembled and ready.
Drier air: less water in pipes and tools.
Pressure to suit: with direct-reading gauge.
Lubricated tools: longer service life for air motors.
Two flow rates: 240 or 450 l/min depending on your air consumption.
🏗️ What it is for
Compressor outlet in mechanical workshops.
Workstations with impact wrenches, grinders or pneumatic drills.
Air installations in industrial units and garages.
Pneumatic machinery that needs lubricated air.
📋 Technical specifications
1/4": M-F threads, 0-12 bar, 240 l/min (14.4 m³/h), max. 60 °C
3/8" and 1/2": M-F threads, up to 16 bar, 450 l/min, max. 60 °C
Components: filter regulator, lubricator and pressure gauge
💡 Pro tip: do not use the FRL on the spray gun line: the oil from the lubricator would ruin the finish. For painting, take the air before the lubricator or use a non-lubricated filter regulator, and drain the filter bowl often.
Complete your installation
Fit the FRL unit at the compressor outlet or at the working outlet and complete it with a quality air hose, universal quick couplers and dedicated pneumatic tool oil in the lubricator. If you also spray paint in the same workshop, keep one outlet with a non-lubricated filter regulator.
Frequently asked questions
Which size should I choose?
1/4" for tools with medium air consumption; 3/8" and 1/2" for impact wrenches, sanders or several outlets.
What oil goes in the lubricator?
Dedicated pneumatic tool oil.
Is it suitable for painting?
Not on the paint line, because it adds oil to the air.
What pressure can it withstand?
12 bar for the 1/4" version and 16 bar for the 3/8" and 1/2" version.
How is it maintained?
Drain the filter regularly and top up the lubricator when the level drops.
