Category buying guide
Clean, stable air is a system requirement, not an accessory.
FRL air preparation selection starts before compressed air reaches the machine: remove contamination, stabilize pressure, add lubrication where required, and create serviceable line preparation assemblies.
Before RFQ
Keep the selection grounded in working details.
- Port size and thread
- Flow or compressor capacity
- Pressure range
- Filter grade, drain, and bowl material
Series comparison
Select each FRL function by air quality, flow, and maintenance plan.
A useful air preparation inquiry includes port size, flow requirement, pressure range, filtration grade, bowl material preference, drain type, and whether lubrication is required by the downstream components.

- Filtration grade
- Useful for
- Protecting downstream parts
- RFQ note
- Need drain style
03 / Stable working pressure
Pressure Regulators
- Start with
- Inlet and outlet range

Lubricators
- Start with
- Flow and oil type
- Useful for
- Lubricated circuits
- RFQ note
- Confirm if lubrication is allowed
05 / Compact two-function prep
Filter Regulators
- Start with
- Port, flow, bowl
- Useful for
- Compact prep stations
- RFQ note
- Check bracket needs
06 / Air quality and oil support
Filter Lubricators
- Start with
- Filtration and flow

- Maintained air lines
- RFQ note
- Confirm oil and bowl material
Choose by air-preparation job
Start with the air quality or pressure job.
Pick the closest FRL use case, then confirm port size, flow, pressure range, filtration, drain, bowl, gauge, and service access before RFQ.
Create a serviceable air entry station.
A complete FRL station is often the fastest route for a new machine when filtration, pressure setting, and lubrication are all required.
Recommended option
Complete FRL unit with bracket, gauge, bowl, drain, and port details.
- Port size
- Required flow
- Pressure range
- Maintenance access
Protect valves and actuators without oil mist.
Many modern circuits avoid lubricators. A filter regulator may be enough when downstream components do not need oil.
Recommended option
Filter regulator with the correct filtration grade and pressure range.
- Lubrication policy
- Filtration grade
- Drain type
- Gauge location
Match an installed air preparation assembly.
The old unit code, port thread, mounting bracket, bowl type, and photo help confirm a matching FRL, filter, or regulator layout.
Recommended option
Matched FRL, filter regulator, or individual air-prep unit.
- Existing model
- Port thread
- Bracket and gauge
- Bowl material
Common FRL uses
Where air preparation units protect the pneumatic line.
FRL use 01
Machine air entry points
Review function, size, pressure, mounting, and inquiry data for FRL Units and Air Preparation Components.
- Confirm main-line port size
- Check flow demand
- Keep bowl and gauge visible
FRL use 02
Dry valve and cylinder circuits
Use filters and filter regulators where downstream valves and cylinders need clean, stable air without added oil mist.
- Clarify lubrication policy
- Choose filtration grade
- Confirm drain and bowl material
FRL use 03
High-pressure or washdown air lines
Use metal-cup, high-pressure, or stainless air-prep components where standard bowls are not suitable for pressure, impact, corrosion, or washdown exposure.
- Confirm pressure range
- Check bowl or body material
- Review ambient conditions
Compressed-air tools
Review pressure stability and air capacity before selecting FRL units.
Pair filters, regulators, lubricators, and complete FRL units with pressure-drop, compressor, receiver, and pressure-unit checks.
