Airtac GAFR Adjustable Filter Regulator GAFR30008ASW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASW 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30008ASW
This AirTAC GAFR30008ASW combines a filter and a pressure regulator into a single body, so one compact unit cleans the air and holds a steady outlet pressure. It has no lubricator and only one bowl, the 60 cc condensate bowl, which the automatic drain empties.
The 1/4in port and 500 g mass suit a small machine station or a single pneumatic actuator. It works across 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles for sensitive valves.

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 GAFR30008ASW Is Used
Precision valve control
Feed a single precision pneumatic valve or a small indexing table with the 5 um element, which keeps fine particles away from tight clearances.
Bench assembly station
Mount this 500 g unit on a workbench rail to supply a hand-operated press or a small clamping fixture with filtered, regulated air.
Wet line protection
Use the automatic drain on a humid production line to shed condensate from the 60 cc bowl without scheduled manual draining.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008ASW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports; the 3500 L/min flow envelope at 0.7 MPa inlet sits between the smaller GAFR200 and the larger GAFR400. The PC bowl suits general dry indoor lines, while the automatic drain handles wet or unattended systems without manual checks. The 5 um element filters finer than the standard 40 um, but needs more frequent service. The included bracket mounts the 500 g unit securely, and the fitted gauge reads MPa/psi on the PT thread. If oil is needed downstream, order the matching GAFC300-08 combination instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 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 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 GAFR30008ASW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the unit weighs 500 g.
The A code means an automatic drain, which expels condensate from the 60 cc bowl without manual intervention. This suits wet lines or unattended operation, unlike the blank drain option that ships with both semi-auto and manual drains.
