Airtac GAR Air Regulator GAR40015LJK
The AirTAC Airtac GAR Air Regulator GAR40015LJK is a genuine compressed-air pressure regulator. It sets and holds a steady downstream pressure across the 0.05 - 0.4 MPa range, with 1/2" 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 GAR40015LJK
The AirTAC GAR40015LJK is a regulator-only unit that takes a higher supply pressure and holds a steady, lower downstream pressure you set with the knob. It does not filter, clean, or dry the air, and it has no drain bowl or filter element - for clean air you need a separate GAF filter or a GAFR unit upstream.
This lower-pressure (L) model regulates from 0.05-0.4 MPa (7-58 psi) and carries a 1/2in port on a 570 g body. The pressed-in self-locking knob keeps the setpoint from drifting when the machine vibrates or the knob gets knocked, so a calibrated low-pressure setting stays put 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 GAFR400 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 GAFR400-15 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 GAR40015LJK Is Used
Low-pressure pneumatic clamping
Set a delicate 0.15 MPa (22 psi) clamp force on a fixture holding thin-walled parts. The L type's finer low-band resolution lets you dial in a repeatable light grip without over-squeezing the workpiece.
Lab air supply for sensitive instruments
Feed a regulated 0.2 MPa (29 psi) to a lab bench air knife or a calibration fixture. The balanced valve design holds the setpoint as the building supply fluctuates during the day.
Spray gun or blow-off station
Run a manual spray gun at a consistent low pressure for even coating. The self-locking knob keeps the setting stable even when the gun hose gets tugged or the panel vibrates.
Is the Airtac GAR Air Regulator GAR40015LJK the Right Regulator?
Choose the GAR400 body when your line needs a 1/2in port and the 570 g mass tells you this is a mid-size regulator that needs a proper panel or bracket mount, not support from the tubing. The L type is for low-pressure work only: it regulates 0.05-0.4 MPa (7-58 psi) and cannot reach a 0.5-0.6 MPa setpoint at all, so pick the S type if you need standard shop pressure. This unit has the circular gauge fitted (MPa/psi scale on PT threads) and the J code means the mounting bracket is omitted - plan for panel mounting or an existing bracket. The K code adds a reverse-flow (reflux) valve to the outlet. If the air also needs cleaning, step up to the matching GAFR400-15 filter-regulator or put a GAF filter upstream. The standard S type spans about 2.4x this L type's adjustable band (0.85 MPa vs 0.35 MPa), so the L gives finer resolution only if you stay inside its low range.
Quick checklist
- ✓ Body size for your air demand (1/2" 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 GAFR400
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 570 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 GAFR400-15 filter-regulator as your air-prep needs grow.
Airtac GAR Air Regulator GAR40015LJK FAQ
The GAR40015LJK is a lower-pressure regulator with a 1/2in port and a 570 g body. It regulates from 0.05-0.4 MPa (7-58 psi), with a max supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -20 to 70 C. It has a circular gauge fitted with an MPa/psi scale, no mounting bracket, and a reverse-flow (reflux) valve attached.
The L type is designed for low-pressure applications only, regulating from 0.05-0.4 MPa (7-58 psi) instead of the standard 0.05-0.9 MPa (7-130 psi). This gives finer resolution over the low band, but it cannot reach a 0.5-0.6 MPa setpoint at all. If your machine needs standard shop pressure, choose the S type instead.
