The AirTAC Airtac GAFR Filter & Regulators GAFR20008ST 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 AirTAC GAFR20008ST puts a filter and a regulator together inside a single body. Air first spins through a diversion structure that flings liquid water and solid grain down into the 25 cc drain bowl, then a balanced mechanism sets the outlet anywhere from 0.15 to 0.9 MPa (20-130 psi). A pressed-in self-locking knob keeps that setting from creeping when the compressor line vibrates, and the 40 um element covers ordinary shop-air cleanliness. No lubricator exists in this unit; it filters and regulates only. Because the 200-size body weighs just 290 g and takes a 1/4in port, it is the right class for one actuator, a small jig or a compact bench machine rather than a plant header. The circular gauge comes fitted and clips onto the body, the mounting bracket comes in the box, and the NPT threads pair with a gauge that reads in psi and bar. Its plotted curve at 0.7 MPa inlet runs to 2000 L/min, and condensate leaves through the semi-auto drain or by hand whenever you choose.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in psi / bar, set by the NPT 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 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.

A compact clamp or testing jig on a 1/4in line gets clean, settled air: the 40 um element strips water and grit while the regulator holds a steady clamp force between 0.15 and 0.9 MPa.
Small semi-automatic labelers and sealers run off point-of-use air. The fitted circular gauge lets an operator read the psi setting at a glance, and the semi-auto drain clears collected condensate between shifts.
Where a test fixture needs repeatable air pressure, the balanced regulator keeps the outlet stable even as the shop compressor cycles, and the NPT threads accept standard psi/bar instrumentation.
The 200 body with an 08 code gives you a 1/4in port, the smallest stocked GAFR frame after the 20006. If your line draws harder than the 2000 L/min plotted envelope at 0.7 MPa inlet, step up to the GAFR300 body, which is plotted to 3500 L/min and carries a 60 cc drain bowl. The blank bowl code here is polycarbonate (PC); specify C for a metal bowl or N for nylon if the surroundings call for it, and confirm chemical compatibility from the datasheet since no solvent or impact data is printed. This SKU leaves the drain position empty, so both a semi-auto drain and a manual drain are fitted; adding A instead would give you an automatic drain for unattended lines. The S type covers 0.15-0.9 MPa; if your circuit never exceeds 0.4 MPa, the L variant exists, but it is the wrong part the moment the machine might need more. Bracket and gauge are both included, the 40 um element is the standard grade, and the T code means NPT threads with a psi/bar gauge scale. If the circuit downstream needs oil mist, order the matching GAFC200 combination rather than expecting this unit to lubricate. For service planning, remember that the GAFR300's 60 cc drain bowl holds about 2.4x the condensate of this model's 25 cc bowl, so this smaller unit will need drain attention roughly twice as often.
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 GAFC200-08 combination; do not expect an oil mist from this unit.
It is a filter and regulator in one body for air. Pressure adjustment spans 0.15-0.9 MPa (20-130 psi) on this standard S type. Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Working temperature is -5 to 70 C and the unit must not freeze. The condensate bowl holds 25 cc, the body weighs 290 g, the element is 40 um, the port is 1/4in NPT, and the plotted flow curve at 0.7 MPa inlet reaches 2000 L/min.
The T code selects NPT threads for the ports, and it also sets the scale of the supplied circular gauge to psi and bar. If your operators read bar and MPa instead, order the same unit with the G code; leaving the position blank gives PT threads with an MPa/psi gauge. The rest of the build, including the 25 cc PC bowl, semi-auto plus manual drains and the included bracket, stays the same.
