The AirTAC GR30015F2GK AirTAC Air Pressure Regulator G1/2 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 PT1/2" 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 GR30015F2GK is an AirTAC GR300 air pressure regulator for compressed air, built purely for regulation: it holds a steady downstream pressure from an upstream supply that can swing. This configuration carries a G1/2 (1/2 in) port, adjusts across 0.05-0.9 MPa (7-130 psi), and accepts up to 1.0 MPa (145 psi) at the inlet. The embedded square gauge is fitted with a psi scale, and the K code means a reverse (check) valve is built in, so downstream pressure is held if the upstream supply drops. A mounting bracket is included, and the GR300 is also panel-mountable. GR units work from -20 to 70 C, a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a low-pressure type (up to 0.4 MPa), gauge scales in MPa, psi or bar, an external round gauge, G or NPT thread variants, and a no-bracket build. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 clamping pressure for air-actuated clamps and hold it through supply fluctuations, with the check valve keeping the clamp from releasing if the main line drops.
Feed cylinder-driven sealing, forming and eject stations on a packaging line from a regulated branch, so each station sees the pressure it was set up with.
Regulate the supply to gripper and end-of-arm tooling circuits on an assembly cell, holding a repeatable setpoint for delicate part handling.
Start with the size step: 200, 300, 400 or 600, each stepping up in port size and flow capacity, and match it against the air demand of the circuit. For this GR300 the 1/2 in port suits lines where a 1/4 in unit would choke flow. Choose the gauge scale you read on site (this unit ships with a square psi gauge; MPa and bar scales are available), and decide whether you want the reverse/check valve (K) that holds downstream pressure on supply loss. Thread is PT as the standard, with G (BSPP) and NPT as orderable options; a no-bracket version (J) exists if you panel-mount. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR regulator flow as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow figures from the datasheet so you can size the unit correctly before ordering.
K means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is lost. It is an option: the same regulator without the check valve carries no K in the code. You can also order different gauge scales, G or NPT threads, or a low-pressure type.
