The AirTAC GAR Air Regulator GAR30010SJ is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with 3/8" ports and a built-in circular pressure gauge. It regulates pressure only — it does not filter the air or remove water.
The GAR30010SJ is an air pressure regulator that takes a higher supply and holds a steady downstream pressure you set with the knob and read on the circular gauge. It does not filter, clean, or dry the air, and it has no drain bowl or filter element.
This standard-type unit regulates 0.05-0.9 MPa (7-130 psi) with a 3/8in port and a 300 g body. The pressed-in self-locking knob keeps the set pressure from drifting when the machine vibrates, so a clamp or tool holds its force through a shift.

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 GAFR300 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 GAFR300-10 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.

Set 0.4 MPa to a pneumatic clamp on a drill fixture. The self-locking knob holds the force steady through repeated cycles, and the 3/8in port feeds the cylinder directly.
Regulate a die grinder or air screwdriver on a repair bench. The 300 g body mounts to a panel, and the gauge lets the operator confirm the tool runs at the rated pressure.
Feed a prototype test jig with a stable 0.6 MPa from a shop line. The balanced design holds the setpoint as the upstream supply fluctuates, keeping test conditions repeatable.
Choose the GAR30010SJ when a 3/8in line needs a standard 0.05-0.9 MPa regulated band and you will mount the regulator to a panel or existing bracket, since the J code omits the mounting bracket. The fitted circular gauge reads MPa/psi on the PT thread, matching the crew's usual units. If the air also needs cleaning, step up to the matching GAFR300-10 filter-regulator or add a GAF filter upstream, because a plain GAR does not remove water or particles. The standard type's adjustable span of 0.85 MPa is about 2.4x the lower type's 0.35 MPa band, giving you a much wider setpoint range.
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 GAFR300-10 filter-regulator as your air-prep needs grow.
The GAR30010SJ regulates air from 0.05 to 0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to 70 C. The unit weighs 300 g and has a 3/8in port.
The J means the mounting bracket is not included. You mount this regulator to a panel or use your own existing bracket. The gauge is still fitted, and the thread is PT with an MPa/psi scale.
