The AirTAC Airtac GAR Air Regulators GAR20008ST is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 1/4" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.
The AirTAC GAR20008ST is a compressed-air pressure regulator and nothing more. It steps a higher, varying supply down to a steady outlet pressure you dial in on the knob, protecting every tool and cylinder downstream from supply swings. It does not filter the air, separate water, or catch particles, so it must never be bought expecting clean-air duty. This version carries a 1/4in port on the GAR200 body (170 g), the standard S type regulating 0.05-0.9 MPa (7-130 psi), NPT threads with a gauge dial marked psi/bar, and a mounting bracket in the box. The circular gauge with clip and magnifier reads at a glance and frees panel space, while the pressed-in self-locking knob holds the setting through vibration so a line that runs unattended all shift keeps the same force at the actuators.

Specifications follow the official AirTAC GAR catalogue (pages 228-229). This is a regulator only — it sets and holds a downstream pressure but does not filter the air or separate water. To clean the air as well, use the matching GAFR200 filter-regulator or add a GAF filter upstream. Never run above the 1.5 MPa (215 psi) proof pressure.

A GAR regulates pressure but does not filter — there is no bowl, element or drain code. Need to clean the air too? The matching GAFR200-08 is the same regulator with a built-in filter.
All bodies share the same 0.05-0.9 MPa (S) regulated range, 1.0 MPa max and 1.5 MPa proof; the body number sets the port size and the flow the regulator can pass. Bigger ports feed higher air demand. The catalogue plots a flow curve at 0.7 MPa inlet but prints no numeric envelope, so size by port and weight and confirm the curve for a real duty point.

A single clamp cylinder fed through a 1/4in line needs a fixed force every cycle. Set the pressure once on the self-locking knob and the clamp repeats the same grip shift after shift.
Air ratchets, die grinders and blow guns at a repair bench run best at a set pressure. This regulator with its psi/bar gauge gives the technician a visible, adjustable supply at the point of use.
Bench-top filling or labelling stations often need gentle, repeatable actuator pressure. Dial the exact value in the 0.05-0.9 MPa band and the balanced valve keeps it there as the compressor load changes.
Choose the GAR200 body when your line runs 1/4in ports and light duty; the next size up, GAR300 at 300 g, is the step for 3/8in and 1/2in lines. Pick the S type here because its 0.05-0.9 MPa span covers normal plant setpoints; the L variant tops out at 0.4 MPa (58 psi) and cannot reach a typical 0.5-0.6 MPa machine setting at all. The gauge is fitted on this code and, being a T (NPT) thread version, its dial is scaled psi/bar, which suits crews working in imperial units. The bracket is included, so you can panel mount or bolt it straight to a frame. If the air also has to be clean, put a GAF filter upstream or step to the matching GAFR, since a GAR on its own does not clean the air and dirt passing through can foul the valve seat. For perspective on scale, this 170 g GAR200 is roughly one eighth the mass of the 1390 g GAR600 that anchors 3/4in and 1in headers.
Quick checklist
This is a regulator only — it sets and holds pressure but does not filter or lubricate. Add a GAF filter, a GAL lubricator, or step up to the GAFR200-08 filter-regulator as your air-prep needs grow.
Regulated range is 0.05-0.9 MPa (7-130 psi) on this standard S type. Maximum working pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -20 to 70 C and the GAR200 body weighs 170 g with a 1/4in port.
The final letter T in the code fixes an NPT thread, and AirTAC pairs NPT units with a dial scaled psi/bar. A PT-threaded version reads MPa/psi and a G-threaded version reads bar/MPa, so pick the thread letter that matches the units your crew reads every day.
