The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASNWK 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 3/8" 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.
The GAFR40010ASNWK is a filter and regulator combined into a single body, so incoming air is spun to separate liquid water and solid particles before a balanced regulator sets a steady outlet pressure. This 3/8in unit works across 0.15-0.9 MPa (20-130 psi) and uses a 5 um element for finer filtration.
With a 100 cc condensate bowl and 880 g mass, this mid-range body suits machine headers where space is tight but flow demand is real. The automatic drain handles wet lines without manual attention, while the included mounting bracket secures the unit to a panel or frame.

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 GAFR400 is 1/4" 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 GAFC400-10 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 3/8in line to a CNC machine's pneumatic controls, where the 5 um element protects precision valves from fine abrasive dust and the automatic drain keeps the bowl from filling during long shifts.
Mount this unit on a panel above an assembly station, using the included bracket to support the 880 g body while supplying filtered, regulated air to multiple hand tools and actuators.
Use the GAFR40010ASNWK on a test bench where a steady 0.15-0.9 MPa output is needed for cylinder cycling, with the 100 cc bowl handling condensate from a humid compressor line.
Choose the GAFR400 body when 3/8in ports and a 100 cc drain bowl match your flow needs; step down to GAFR300 (60 cc bowl, plotted to 3500 L/min at 0.7 MPa inlet) for lighter lines or up to GAFR500 (108 cc bowl) for more capacity. The PC bowl suits general shop air, the 5 um element traps finer particles for sensitive valves, and the automatic drain removes condensate without manual checks. The mounting bracket is included, the gauge is omitted (1/4in connection available), and the reverse-flow valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC400-10 combination instead. 1.0 MPa max supply 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 GAFC400-10 combination; do not expect an oil mist from this unit.
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), and proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C, the drain bowl holds 100 cc, and the unit weighs 880 g. It uses a 5 um element and has an automatic drain.
The N in the code means no gauge is supplied, so you cannot read the set pressure directly. The GAFR400 body has a 1/4in gauge connection, so you can add a compatible pressure gauge later if needed.
