The AirTAC GAR Air Regulators GAR100M5S is a genuine compact pressure regulator in a 59 g body. It sets and holds a steady downstream pressure across the 0.05 - 0.9 MPa range, with a M5 port and a built-in circular gauge. It regulates pressure only — it does not filter the air.
The GAR100M5S is the compact AirTAC pressure regulator in its smallest size class, built around an M5 port for miniature circuits and hand-held tools. It sets and holds a reduced downstream pressure across the standard 0.05 to 0.9 MPa (7-130 psi) band. Regulating is all it does: no filtering, no water separation, no drain. Where air quality matters, add a GAF100 filter ahead of it or spec the GAFR100, which folds a filter into the same body.
The balanced adjustment mechanism keeps the output steady as inlet pressure varies, and the pressed-in knob locks itself against vibration so settings survive knocks. Its circular gauge, held by a clip with a magnifier, is scaled in MPa and psi on this PT version. Maximum inlet is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the 59 g unit runs from -5 to 70 C.

Specifications follow the official AirTAC GAR catalogue (GAR100 page). The GAR100 has no reflux (K) option. This is a regulator only — it sets and holds a downstream pressure but does not filter the air. To clean the air as well, use the matching GAFR100 filter-regulator or add a GAF filter upstream.

A GAR regulates pressure but does not filter. Need to clean the air too? The matching GAFR100M5 is the same regulator with a built-in filter.
The GAR100 is the smallest body, for a small tool or branch line. For a bigger port and higher air demand, step up to the GAR200-600 range.

Regulate the air to a small hand tool or pick-and-place nozzle. The M5 port plugs straight into compact manifolds where a 1/8in fitting would be oversized.
Carry precise pressure to a lightweight device. At 59 g with a self-locking knob, the setting survives transport knocks and machine vibration.
Mount the included bracket inside a control cabinet and reduce main-line pressure for one low-flow branch. The MPa/psi gauge reads at a glance through the magnifier.
Choose the M5 port when your circuit is too small for a 1/8in fitting, and the S type when you want the full 0.05-0.9 MPa (7-130 psi) span. This SKU leaves every option letter off, so you get the PT thread with an MPa/psi gauge scale, the circular gauge fitted, and the mounting bracket included. A panel or bracket mount keeps the 59 g body tidy inside a compact machine. If your air use grows beyond what an M5 feed supports, the GAR200 is the next size up, and a GAFR100 handles jobs that also need clean air. One useful comparison: the GAR200 weighs 170 g, roughly 2.9x the mass of this 59 g unit.
Quick checklist
This is a regulator only — it sets and holds pressure but does not filter or lubricate. Add a GAF filter or step up to the GAFR100M5 filter-regulator as your air-prep needs grow.
The standard S type regulates 0.05 to 0.9 MPa (7-130 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and weighs 59 g. The proof value is a burst-test margin, never a setpoint.
Both ports sit on the same GAR100 body and share identical pressure figures. The M5 thread suits very small tools and tight manifolds, while the 1/8in option (code 06) fits conventional branch lines. Your fitting size, not the regulator, decides which to order.
