Ensure your compressed air system delivers clean, consistent and properly lubricated air with our range of Air Filter Regulator Lubricator (FRL) units. These essential pneumatic accessories protect your air tools and machines from moisture, dirt and pressure fluctuations, helping extend service life and improve performance.
FRL units combine three critical components in one compact assembly:
Filter — removes water, oil and solid contaminants.
Regulator — stabilises and sets the correct air pressure.
Lubricator — introduces fine oil mist to protect internal tool parts.
Whether you’re running air impact wrenches, grinders, spray guns or other air tools, a good FRL ensures better reliability, less wear and smoother operation.
Protects tools from moisture and corrosion — moisture in compressed air causes rust and premature wear in tools and actuators.
Stable pressure delivery — prevents damage caused by over-pressure and ensures consistent tool performance.
Extends tool life with proper lubrication — lubricated air reduces friction and heat in pneumatic motors and valves.
Simplified installation — combined unit reduces plumbing complexity and leak points.
We stock quality pneumatic prep units with different port sizes to suit your workshop setup:
Filter Regulator Kits (1/4″ & 1/2″ BSP) — combined unit with filter and regulator.
Individual Filters, Regulators & Lubricators — customise your air prep setup.
Wall Brackets and Accessories — convenient mounting options.
These units connect directly to your compressor line to improve air quality and protect downstream pneumatic tools.
Air enters the filter, where moisture and solid particles are captured.
The regulator adjusts the downstream pressure, delivering stable air ideal for tools and equipment.
The lubricator adds a controlled oil mist, reducing internal wear in moving parts.
This three-stage conditioning process ensures peak performance and longevity from your air-powered tools.
Q: What is an Air Filter Regulator Lubricator (FRL)?
A: An FRL is a combined pneumatic air treatment unit that filters contaminants, regulates pressure, and lubricates the air supply — critical for clean, stable and tool-safe compressed air.
Q: Do I really need a regulator on my air compressor?
A: Yes. A regulator ensures your tools receive consistent and correct pressure, which improves performance and prevents damage caused by pressure surges.
Q: How often should I maintain the FRL unit?
A: Drain or clean filter bowls regularly and refill the lubricator with recommended pneumatic oil to ensure peak protection and performance.
Q: Can FRLs improve pneumatic tool life?
A: Yes — by removing moisture and debris and adding lubrication, FRLs significantly reduce friction and wear, extending tool life.
Q: What size FRL do I need for my workshop?
A: Choose port sizes (e.g., 1/4″, 3/8″, 1/2″) based on your compressor’s capacity and tool requirements. Larger workshop setups typically benefit from higher flow and larger port sizes.
