Airtac GAFR Adjustable Filter Regulator GAFR200C08ALK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08ALK 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 GAFR200C08ALK
The AirTAC GAFR200C08ALK is a filter and regulator combined into a single body, eliminating the need for separate components. This 1/4in unit weighs 290 g and features a metal bowl with an automatic drain, while its lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi).
A diversion structure spins incoming air to separate liquid water and solid particles, depositing them into the 25 cc drain bowl. The balanced, self-locking regulator holds the outlet pressure steady as supply varies, and the pressed-in knob resists drift from vibration. A 40 um element handles standard filtration, and the reverse-flow valve is fitted as an ordering difference.

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 GAFR200C08ALK Is Used
Precision pressure setting
Use the lower-pressure type to set a precise 0.2 MPa (29 psi) for a delicate pneumatic clamp. The balanced regulator holds the setpoint steady even if the shop supply fluctuates.
Compact machine build
Mount this 290 g unit on a small jig or single actuator. The included bracket secures it to a panel, and the integrated filter and regulator save rail space compared to separate parts.
Unattended line operation
The automatic drain clears condensate from the 25 cc metal bowl without manual checks. This suits a wet line where regular draining is impractical, keeping the filter working.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08ALK the Right Air-Prep Unit?
Choose the GAFR200 body for 1/8in or 1/4in ports, with a flow curve plotted to 2000 L/min at 0.7 MPa inlet. The metal bowl (C) is a build choice; the common spec of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm compatibility for aggressive surroundings. This model has an automatic drain (A) for unattended lines, the lower-pressure type (L) for 0.15-0.4 MPa, the mounting bracket included, a fitted gauge with MPa/psi scale, a 40 um element, and the reflux valve (K). If oil is needed downstream, order the matching GAFC200-08 combination. Note that 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 GAFR200C08ALK FAQ
The GAFR200C08ALK is a filter & regulator with a 1/4in port. Its pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 25 cc drain bowl, and weighs 290 g.
The L code designates a lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15-0.9 MPa. This is for applications needing a finer adjustment at lower pressures. If your machine may require more than 0.4 MPa, the standard type is the correct choice.
