The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALK 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 GAFR200N08ALK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. It cleans incoming air via a diversion structure that spins out liquid water and solid particles, then delivers a steady outlet pressure through a balanced, self-locking regulator. This model has a 1/4in port, a 0.15-0.4 MPa (20-58 psi) lower-pressure range, and a 40 um element.
Its nylon bowl and automatic drain make it suited for applications where condensate must be expelled without manual intervention. The unit weighs 290 g, and its gauge connection is 1/8in. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet stable in dynamic environments.

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 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 precision fixture or a small indexing table that needs clean, regulated air at a lower pressure. The automatic drain keeps the bowl from filling during long production runs.
Supply a laboratory bench with filtered air at a stable 0.15-0.4 MPa for pneumatic controls on test equipment. The nylon bowl resists fogging, allowing visual confirmation of condensate level.
Power a small pneumatic hand tool or a single-acting cylinder on a workbench. The compact 290 g body mounts directly to a frame, and the self-locking knob holds the pressure setpoint.
Choose the GAFR200N08ALK for a compact, lower-pressure air prep station with a 1/4in port. The nylon bowl offers an alternative to PC or metal, while the automatic drain handles wet lines without manual checks. The included bracket simplifies mounting, and the fitted gauge with MPa/psi scale shows the set pressure directly. The 40 um element handles general shop air; if finer filtration is needed, consider the 5 um element option. The reverse-flow (reflux) valve is fitted as an ordering difference. If lubrication is required downstream, order the matching GAFC200-08 combination instead. Note that 1.0 MPa max supply leaves 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 working 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 in temperatures from -5 to 70 C and must not freeze. The drain bowl capacity is 25 cc, and the unit weighs 290 g.
The 'K' indicates that a reverse-flow (reflux) valve is fitted to this unit. This is an ordering difference from models without the 'K' suffix. The function of the valve is detailed in the full AirTAC catalogue; this model simply includes it as a factory-fitted option.
