The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASK 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 GAFR30008ASK is a filter and regulator combined in a single body, saving rail space and reducing potential leak points compared to separate units. It handles 1/4in ports and delivers a regulated output from 0.15 to 0.9 MPa (20-130 psi) with a 40 um filter element.
The integrated diversion structure spins incoming air to separate liquid water and solid particles into the 60 cc condensate bowl. The balanced, self-locking regulator holds the set pressure steady as supply varies, and the pressed-in knob resists drift from vibration.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. 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 with stable pressure for consistent part holding. The 1/4in port and 500 g body suit compact machine stations.
Supply clean, regulated air to a laboratory test setup or calibration bench. The 40 um filter protects sensitive instruments and the gauge shows set pressure at a glance.
Power a single actuator or small valve manifold on an assembly station. The automatic drain reduces maintenance on lines with occasional moisture.
Choose the GAFR300 body for 1/4in or 3/8in ports; it weighs 500 g and its flow curve is plotted to 3500 L/min at 0.7 MPa inlet. The PC bowl is the standard choice, while the automatic drain (A) suits unattended or wet lines. This model includes the mounting bracket and a circular gauge with MPa/psi scale, plus the reverse-flow (reflux) valve (K) as an ordering option.
The 40 um element handles general shop air; select the 5 um (W) version for finer filtration. If the line needs oil 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
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 GAFR30008ASK is a filter & regulator with a 1/4in port, working pressure range 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, 60 cc drain bowl, and 500 g weight. It has a 40 um element and an automatic drain.
The K indicates a reverse-flow (reflux) valve is fitted. This is an ordering difference from models without the K code. The catalogue does not specify its function in our data, so confirm the application requirement before ordering.
