Airtac GAR Air Regulator GAR30008SJ
The AirTAC Airtac GAR Air Regulator GAR30008SJ 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.

About the Airtac GAR Air Regulator GAR30008SJ
The GAR30008SJ is an air pressure regulator that takes a higher supply pressure and holds a steady, lower 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 model regulates from 0.05-0.9 MPa (7-130 psi) with a 1/4in port and a 300 g body. The pressed-in self-locking knob prevents the set pressure from drifting due to vibration or accidental knocks, so your downstream equipment sees a stable setting.

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 GAFR300-08 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.

Where the Airtac GAR Air Regulator GAR30008SJ Is Used
Precision clamping
Set a stable 0.3 MPa for a pneumatic clamp on a small assembly fixture, holding parts firmly without supply pressure swings affecting the grip.
Single tool pressure
Regulate air to one air tool or a small cylinder, keeping the downstream pressure constant even when other equipment draws from the same supply line.
Test bench setup
Use on a test bench to provide a repeatable, adjustable pressure for calibrating gauges or testing components, with the gauge giving a clear local readout.
Is the Airtac GAR Air Regulator GAR30008SJ the Right Regulator?
Choose the GAR30008SJ when you need a 1/4in port regulator without a mounting bracket, since the J code omits the bracket for panel mounting or an existing bracket. The standard S type covers 0.05-0.9 MPa (7-130 psi), suitable for most industrial lines, while the L type only reaches 0.05-0.4 MPa (7-58 psi) for low-pressure work. The circular gauge reads in MPa/psi with PT threads, and the 300 g body suits panel mounting rather than tubing support. If the line also needs clean air, use a GAFR300-08 filter-regulator or a GAF filter upstream, as this unit does not filter. The standard type's adjustable band is about 2.4x the L type's span, giving you far more setpoint flexibility.
Quick checklist
- ✓ Body size for your air demand (1/4" here)
- ✓ Type S (0.05-0.9) or L (0.05-0.4 MPa)
- ✓ Gauge fitted, or no gauge (N)
- ✓ Thread PT / G / NPT (sets gauge scale)
- ✓ Bracket kept or removed (J)
- ✓ Need filtration too? Use GAFR300
Installation & Setting Notes
- check Install with the airflow arrow: IN to OUT, knob accessible.
- check Put a filter (GAF or a GAFR) UPSTREAM — a regulator does not clean the air.
- check Set pressure by turning the knob up to the target, then press it in to lock.
- check Keep supply at or below the 1.0 MPa (145 psi) max working pressure.
- check Never exceed the 1.5 MPa (215 psi) proof pressure.
- check Support the 300 g unit on its panel or bracket, not on the tubing.
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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR30008SJ FAQ
The GAR30008SJ regulates air from 0.05-0.9 MPa (7-130 psi) with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -20 to 70 C and weighs 300 g. The unit has a 1/4in port, a circular gauge, and no mounting bracket.
The J in the model code means the mounting bracket is omitted. This suits installations where the regulator is panel-mounted or secured with an existing bracket, saving space and reducing cost when the bracket is not needed.
