Airtac GAFR Adjustable Filter Regulator GAFR30008LNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008LNW is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 1/4" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30008LNW
The GAFR30008LNW is a filter and regulator combined into a single body, so it cleans incoming air and sets a steady outlet pressure without needing separate units. This 1/4in version weighs 500 g and uses a 5 um element to trap fine particles for sensitive equipment.
Its lower-pressure regulator works from 0.15 to 0.4 MPa (20-58 psi), and the 60 cc condensate bowl collects water and solids spun out by the diversion structure. The mounting bracket is included, and the PT thread option suits standard installations.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR300 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC300-08 F.R.L. combination instead.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFR Adjustable Filter Regulator GAFR30008LNW Is Used
Precision valve control
Feed a 5 um filtered, regulated air supply to precision pneumatic valves that need consistent low pressure without contamination.
Bench test setups
Use on a test bench where a compact 1/4in unit with a lower pressure range suits delicate measurement instruments and controlled actuation.
Single actuator lines
Protect a single small cylinder or air tool with filtered air and a stable 0.4 MPa maximum pressure, all in one compact body.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008LNW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in ports when a compact unit with a 60 cc drain bowl fits your line. The lower-pressure type tops out at 0.4 MPa, so confirm your system never needs more than that before selecting this model. The 5 um element provides finer filtration than the standard 40 um, ideal for precision valves or instrument air, though it will need more frequent service. This unit ships with both semi-auto and manual drains, giving you flexibility for scheduled or manual emptying. The included bracket simplifies mounting, while the absence of a gauge means you will need to add one via the 1/8in connection to read outlet pressure. If your line requires lubrication downstream, order the matching GAFC300-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa regulated ceiling.
Quick checklist
- ✓ Body size for your peak flow (1/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30008LNW FAQ
The GAFR30008LNW is a filter & regulator with a 1/4in port, working pressure range of 0.15-0.4 MPa (20-58 psi), and a maximum pressure of 1.0 MPa (145 psi). Its proof pressure is 1.5 MPa (215 psi), and it operates from -5 to 70 C. The drain bowl holds 60 cc, and the unit weighs 500 g.
The L code designates a lower-pressure regulator that tops out at 0.4 MPa, suited for applications needing gentle, stable pressure. The N code means no gauge is supplied, so you must add one to the 1/8in connection to monitor outlet pressure.
