The AirTAC GFR20008LJC2GK AirTAC Filter Regulator G1/4, Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20008LJC2GK is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is the low-pressure regulator type, sized for a G1/4 (1/4 in) port with G (BSPP) thread. It carries the standard 40 um filter element, a differential-pressure drain on the PC (polycarbonate) bowl, a round pressure gauge with psi scale, and a built-in reverse (check) valve; no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options that include manual or automatic drains, a finer 5 um element (code W), alternative gauge scales, G or NPT threads, and mounting brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no 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. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

In a paint or coating booth where atomizing air must be held at a low set pressure, this unit cleans the supply of water and pipe scale and regulates it in one body, while the check valve holds the downstream setting if the main supply dips.
Carton sealing and wrapping machines that run their pneumatic clamps and creasing cylinders at reduced pressure get filtered, regulated air at the machine drop, with the 40 um element protecting the sealing-head valves from particulates.
A bench-top glue or sealant dispensing station working at low set pressures benefits from combined filtration and regulation at the panel, keeping the metering valve supply clean and steady for consistent bead placement.
The real choices in this family are the size and port step (200/300/400/600 covering 1/8 to 1 in) matched to the air demand of your circuit; the drain type (differential-pressure as fitted here, automatic, or manual); the filter grade (40 um standard, 5 um with code W for finer protection); the gauge (embedded square as standard, external round as on this unit, with MPa, psi or bar scales); and the thread (PT is the standard, with G and NPT as order options). Brackets are optional on GFR. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow data as curves rather than a single rated figure, so we do not quote a flow number here. Send us your line pressure, port size and air demand and we will confirm the sizing from the datasheet on request.
It marks the low-pressure regulator type, selected where the working set pressure is lower than a standard unit is intended for. The exact regulation range for the low-pressure type is not published, so we confirm it from the datasheet on request. The rest of the code decodes as: size 200, 1/4 in port, G thread, differential-pressure drain, 40 um element, round psi gauge, and a fitted reverse (check) valve.
