The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASNW 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 GAFR40010ASNW is a filter and regulator combined in a single body, eliminating the need for separate filter and regulator units. This 3/8in model handles standard pressures from 0.15 to 0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles.
Its diversion structure spins incoming air to separate liquid water and solid debris into the 100 cc drain bowl. The pressed-in self-locking knob resists set-pressure drift from vibration, while the automatic drain clears condensate without manual intervention.

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 bank of precision pneumatic valves that require clean, 5 um filtered air at a stable pressure. The balanced regulator holds the setpoint as supply varies.
Supply a medium-sized machine tool's clamping circuit where a 3/8in port matches the manifold. The 100 cc bowl reduces drain frequency compared to smaller units.
Protect actuators on an assembly station from water and particulates. The automatic drain keeps the bowl from filling during long production runs.
Choose this GAFR400 body for medium-flow lines needing a 3/8in port and a 100 cc condensate bowl. It steps up from the GAFR300's 60 cc bowl and 3500 L/min envelope, while the GAFR500 offers a larger 108 cc bowl and 8000 L/min curve at 0.7 MPa inlet. The PC bowl suits general-purpose use; the 5 um element provides finer filtration than the standard 40 um grade. This model includes the mounting bracket and omits the gauge, so the 1/4in gauge connection remains available for a later add-on. The automatic drain handles wet or unattended lines. For lubrication downstream, order the matching GAFC400-10 combination instead. Max supply of 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 GAFC400-10 combination; do not expect an oil mist from this unit.
Working pressure is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g.
The N code means no gauge is supplied. The GAFR400 body has a 1/4in gauge connection, so you can add a compatible AirTAC gauge later to read outlet pressure. Without one, the set pressure cannot be visually verified.
