The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08LJNK 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.
The GAFR200C08LJNK is a filter and regulator combined into one compact body, replacing the need for separate GAF and GAR units. It spins incoming air to separate liquid water and solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator knob that resists vibration drift.
This model has a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 40 um element. It features a metal bowl, a semi-auto plus manual drain, and no gauge, with a 1/8in gauge connection available if one is added later.

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 GAFR200 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 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.

Feed a single pneumatic clamp on a benchtop assembly fixture, where the lower-pressure range prevents over-force on delicate parts.
Provide filtered, regulated air to a small laboratory instrument that requires a stable but modest pressure below 0.4 MPa.
Power a single air tool on a mobile cart, with the metal bowl protecting against knocks in a workshop environment.
Choose the GAFR200 body for small jigs or single actuators where space is tight and a 1/4in port suffices. The metal bowl (C) suits demanding environments, while the lower-pressure type (L) caps output at 0.4 MPa, so confirm your system never needs more. This unit omits the bracket (J) for panel mounting, has no gauge (N), and includes the reverse-flow valve (K) as an ordering difference. If your line needs oil downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 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 GAFC200-08 combination; do not expect an oil mist from this unit.
This filter & regulator has a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 25 cc drain bowl, and weighs 290 g.
The K indicates a reverse-flow (reflux) valve is fitted. This is an ordering difference from models without it; its specific function is detailed in the catalogue. This unit also has no gauge and no bracket, so plan for a panel mount and an optional 1/8in gauge.
