The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASN 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.
The GAFR30008ASN is a filter and regulator combined into a single body, so the incoming air is cleaned and then set to a steady outlet pressure without needing two separate components. This 1/4in unit works in the 0.15-0.9 MPa (20-130 psi) range and uses a 40 um element to trap particles.
A diversion structure spins the air to separate liquid water and solid debris into the 60 cc condensate bowl, while the balanced regulator holds the set pressure as supply varies. The pressed-in self-locking knob resists drift from vibration, and the automatic drain clears condensate without manual attention.

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.

Feed a single pneumatic clamp or fixture on a benchtop assembly station. The 1/4in port and 500 g body suit short local runs, while the automatic drain keeps condensate from reaching the work area.
Provide filtered, regulated air to a laboratory test fixture or calibration setup. The 40 um element protects sensitive instruments, and the balanced regulator holds the setpoint as shop pressure fluctuates.
Supply a small pick-and-place unit or rotary actuator with clean air at a stable pressure. The self-locking knob maintains the setting despite machine vibration, and the 60 cc bowl handles typical shift condensate.
Choose this GAFR300 body for 1/4in ports when you need a 500 g unit with a 60 cc drain bowl, sized between the smaller GAFR200 and the larger GAFR400. The PC bowl suits general shop air, the automatic drain handles wet or unattended lines, and the included bracket simplifies mounting; the no-gauge version leaves a 1/8in connection if you add one later. If the line needs oil downstream, order the matching GAFC300-08 combination instead, since this unit does not lubricate. The 40 um element is the standard choice, and the PT thread matches MPa/psi gauge scales. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum for full output.
Quick checklist
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.
The GAFR30008ASN is a filter & regulator with a 1/4in port, working pressure 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 60 cc drain bowl, and 500 g weight. It has an automatic drain and no gauge, with a 1/8in gauge connection.
The N code after the port means no gauge is supplied, which suits installations where a panel-mounted gauge already exists or where set pressure is checked with a portable tester. The GAFR300 body has a 1/8in gauge connection, so a compatible AirTAC gauge can be fitted later if needed.
