The AirTAC GR30010JF2 AirTAC Air Pressure Regulator PT3/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR30010JF2 is an AirTAC GR-series air pressure regulator for compressed air, providing pressure regulation only - no filtration and no lubrication. This 300-size unit has PT3/8 (3/8 in) ports, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The J code means no mounting bracket is fitted, and the F2 code specifies the embedded square gauge with a psi scale; an external round gauge is available as an option. As a GR unit it carries the widest temperature rating in the G family, -20 to 70 C, and it is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, in PT, G (BSPP) and NPT threads, with optional low-pressure type (up to 0.4 MPa), a reverse/check valve, and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Set a stable, repeatable downstream pressure for a pneumatic clamping or pressing cylinder on a machine frame, with the psi-scale square gauge letting operators dial in and verify the setting at a glance.
Regulate the supply branch feeding sealing jaws, diverters and small actuators on a packaging line, keeping the branch pressure independent of swings elsewhere in the plant air ring main.
Drop the header pressure to a controlled level at the point of use on a factory floor, protecting downstream tools and cylinders from over-pressure while the wide -20 to 70 C rating suits unheated areas.
Start with the port step: this unit is 300 size with PT3/8 ports - move up to 400 or 600 for larger lines, or down to 200 for compact circuits, matching the size to the flow your line needs. Set the outlet range against your actuator requirement: the standard GR covers 0.05-0.9 MPa (7-130 psi), while the L low-pressure type covers up to 0.4 MPa. Choose the gauge scale that suits your team - this configuration is psi on the embedded square gauge, with MPa or bar available. Thread is PT as standard; G (BSPP) and NPT are orderable options. Brackets are optional on GR, which is also panel-mountable, and a reverse/check valve can be fitted if you need to hold downstream pressure.
One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated figure, so we do not quote a flow number here. Send us your line pressure, set pressure and expected air demand, and we will confirm the correct size against the datasheet before you order.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR regulator flow as performance curves rather than a single rated number, so we do not state a flow figure here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet on request before you order.
F is the square embedded gauge fitted to this unit and 2 is the psi scale. If your team works in metric, the same regulator can be ordered with an MPa (scale 1) or bar (scale 3) gauge, or with the optional external round gauge instead - just ask and we will quote the right code.
