Airtac GAFR Adjustable Filter Regulator GAFR200N08ALN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALN 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 40 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 GAFR200N08ALN
The GAFR200N08ALN is a filter and regulator combined in a single body, saving rail space and reducing potential leak points compared to separate units. It delivers air filtered to 40 um and regulated to 0.15-0.4 MPa (20-58 psi) through its 1/4in port, with a nylon bowl and automatic drain.
This lower-pressure model suits applications needing a capped output. The diversion structure spins incoming air to separate liquid water and solid particles into the 25 cc drain bowl, while the balanced regulator maintains the set pressure as supply varies. Weighing 290 g, it is a compact unit for small machines.

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 GAFR200 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 GAFC200-08 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 GAFR200N08ALN Is Used
Precision Fixtures
Feed a single pneumatic clamp or fixture with stable, lower pressure. The 0.4 MPa ceiling protects delicate workpieces from over-force.
Lab Air Supply
Provide filtered, regulated air to a laboratory instrument or test rig requiring a modest, consistent pressure below 0.4 MPa.
Bench Tools
Power a small bench-mounted pneumatic tool or air jet, with the automatic drain handling condensate in humid shop conditions.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALN the Right Air-Prep Unit?
Choose the GAFR200 body for small jigs or single actuators with 1/4in ports. The nylon bowl offers a build alternative to PC or metal, with the same 1.0 MPa max pressure rating. This model has an automatic drain for wet lines, a lower-pressure type capped at 0.4 MPa, and includes the mounting bracket. No gauge is fitted, but the 1/8in connection allows adding one. The 40 um element suits general shop air; the 5 um option is for finer filtration. PT threads with MPa/psi scale are standard. For lubrication downstream, order the matching GAFC200-08 combination. Note that the 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 290 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 GAFC200-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR200N08ALN FAQ
This filter & regulator has a 1/4in port, 0.15-0.4 MPa (20-58 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, -5 to 70 C temperature range, 40 um element, 25 cc drain bowl, and weighs 290 g.
The 'L' code means the regulated output is capped at 0.4 MPa (58 psi), unlike the standard type which goes to 0.9 MPa. This is ideal for applications needing a limited, stable pressure. If your machine may ever require more than 0.4 MPa, choose the standard type instead.
