The AirTAC Airtac GAR Air Regulators GAR20008SJT 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 GAR20008SJT is an air pressure regulator, and nothing more. It takes a higher, varying supply pressure and holds a steady, lower downstream pressure that the operator sets with the knob and reads on the fitted circular gauge. It does not remove water, oil or particles from the air, and it carries no bowl and no drain.
This standard (S) type regulates 0.05-0.9 MPa (7-130 psi) through a 1/4in port and weighs 170 g. The connecting thread is NPT, so the gauge scale reads psi/bar. Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the working temperature span is -20 to 70 C. A pressed-in self-locking knob keeps the setpoint from creeping under vibration.

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.

Hold a fixed pressure for one air screwdriver or impact wrench at a bench station, shielded from swings on the shop compressor header.
A 1/4in port suits a small pneumatic clamp or gripper where the setpoint stays put while the rest of the line fluctuates.
Give a light-duty fixture or test rig its own downstream pressure so operators can dial it in locally and read it on the psi/bar dial.
Pick the 1/4in port when a compact line feeds one tool or a small clamp; stepping up to the GAR300 body brings 300 g against 170 g and larger port choices. This code is the standard S type for general machines; the L variant stops at 0.4 MPa and cannot reach a 0.6 MPa setpoint at all. Note the J option: no mounting bracket is supplied, so plan for panel mounting or an existing bracket. The gauge is fitted and, because the thread is NPT, its scale reads psi/bar for crews working in imperial units. If the air also has to be cleaned, fit a GAF filter upstream or specify the matching GAFR filter-regulator instead. In practical terms, the adjustable band of this S type is about 2.4x that of the L type (0.85 MPa versus 0.35 MPa).
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.
It regulates 0.05-0.9 MPa (7-130 psi) on a 1/4in NPT port. Maximum working pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The rated temperature range is -20 to 70 C and the unit weighs 170 g. It is a regulator only, with no filtering function.
The J position in the code deletes the bracket. Panel mounting or an existing bracket is expected. Codes without the J option include the bracket as standard, so order a plain GAR20008S if you need one supplied.
