The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASK 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 1/2" 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 GAFR40015ASK is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port with a working pressure of 0.15-0.9 MPa (20-130 psi) and a standard 40 um filter element.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 100 cc drain bowl. The balanced, self-locking regulator holds the set outlet pressure steady as supply pressure varies, and the circular gauge with magnifier allows easy reading of the MPa/psi scale.

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 GAFC400-15 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 series of pneumatic actuators on an assembly line with stable, filtered air. The 1/2in port and 100 cc bowl support moderate cycle rates without frequent draining.
Supply a small machine tool's header with clean, regulated air for cylinders and valves. The automatic drain keeps the bowl clear during long production runs.
Protect sensitive packaging machinery from water and particulates. The 40 um element and steady regulation help maintain consistent operation of pneumatic sensors and actuators.
Choose the GAFR400 body for medium-flow lines; its 7000 L/min flow curve at 0.7 MPa inlet is double the GAFR300's 3500 L/min envelope, making it a clear step up for multi-actuator stations. The PC bowl is the standard build, while the automatic drain (A) suits unattended operation or wet supply lines. The included mounting bracket simplifies panel installation, and the fitted gauge shows the set pressure directly. The 40 um element handles general shop air, and the PT thread matches the MPa/psi gauge scale. The reverse-flow (reflux) valve is fitted per the K code. If oil is needed downstream, order the matching GAFC400-15 combination instead. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure accordingly.
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 GAFC400-15 combination; do not expect an oil mist from this unit.
This filter & regulator has a 1/2in port, a pressure range of 0.15-0.9 MPa (20-130 psi), a max 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 100 cc drain bowl, and weighs 880 g. The filter element is 40 um.
The K code indicates the reverse-flow (reflux) valve is fitted. This is an ordering difference from models without the K code. The catalogue does not detail its function in the data we have, so please refer to the official AirTAC documentation for its operational specifics.
