The AirTAC GR200-08 AirTAC Air Pressure Regulator PT1/4 Low-Pressure is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/4" 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 GR200-08 is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady, and it does nothing else. There is no filter element and no bowl in this unit, so it contains nothing to drain and nothing to lubricate. This specific configuration is the low-pressure type, which regulates up to 0.4 MPa instead of the standard range, with a 1/4 in PT port, a round pressure gauge reading in psi, and a reverse (check) valve fitted so downstream pressure is held if the supply side drops. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G family. It ships without a mounting bracket; GR regulators are also panel-mountable.
This is a genuine AirTAC part from the GR200 size class, one of four sizes (200/300/400/600) that step up in port size and flow capacity. Across the GR line you can order standard or low-pressure regulation, a gauge in MPa, psi or bar scale, G (BSPP) or NPT threads instead of PT, a check valve, and bracket or no-bracket mounting. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm the exact flow and datasheet figures for your application on request.

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.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

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.

Adhesive and coating heads on packaging and converting lines often run at low set pressures where a standard regulator range is wasted. The GR200-08's low-pressure regulation up to 0.4 MPa, with the check valve holding the setting if supply dips, suits this job on a 1/4 in PT drop.
Pneumatic valve positioners and pilot circuits on plant skids need a steady, low pilot pressure to hold a control valve where the loop commands. This regulator's psi-reading round gauge lets technicians set and verify the pilot setpoint directly at the panel.
Air-film tables, low-pressure clamps and delicate workholding on machining and assembly fixtures need gentle, stable pressure so parts are held without marking. The GR200-08 regulates that low setpoint downstream of the main FRL, with no filter or bowl to maintain in the fixture drop.
Start with the port step: GR200 carries 1/4 in ports, and the 300/400/600 sizes step up for larger air demand, so match the size to the flow your line needs rather than to the pipe alone. Then decide the regulation range: this unit is the low-pressure (L) type, regulating up to 0.4 MPa, which is the right choice only if your process runs at low set pressures; the standard GR type covers a wider range. Choose the gauge scale (MPa, psi or bar) and the thread (PT standard, G or NPT to order), and add the K option if you want the reverse/check valve fitted, as on this model. Bracket or no-bracket is also a decodable choice.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the flow curve and datasheet figures against your application 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 state a number here. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the flow curve and datasheet figures for this exact model on request.
The L in the code marks the low-pressure regulator type, which regulates up to 0.4 MPa instead of the standard range, so it is for circuits that run at low set pressures. The K marks a fitted reverse (check) valve, which holds downstream pressure if the supply side drops. The C2 gives you the round gauge reading in psi, and the J means no mounting bracket is included.
