The AirTAC GFR20008LC2GK 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 AirTAC GFR200-08 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/4 (BSPP) port, a 40 um standard filter element, a differential-pressure drain on the PC bowl, and the low-pressure (L) regulator type. A round gauge scaled in psi and a reverse (check) valve are fitted, and the mounting bracket is included. Because the exact regulating range of the low-pressure type is not published in the catalogue, confirm it against your set pressure before ordering.
This is a genuine AirTAC part from the GFR200 series, one of four sizes (200/300/400/600) with ports from 1/8 to 1 inch and options including 5 um filtration (code W), automatic or manual drains, alternative gauge scales, and G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

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.

Supplying filtered, regulated air to the clamping cylinders on a machining-centre fixture, with the fitted check valve blocking reverse flow and the 40 um element keeping debris out of the clamp valves.
Regulating supply air to spray or blow-off nozzles on a packaging line that runs at low set pressures, with the round psi gauge giving the operator a direct readout of the regulated pressure.
Feeding filtered, regulated air to diverter and stopper cylinders along a conveyor line, with the differential-pressure drain clearing condensate from the PC bowl during operation.
Choose the size by port and air demand: this 200-size unit carries a G1/4 port, and you step up to 300, 400 or 600 when the line needs more flow. Since flow is published as curves and not as a single rating, ask us to confirm the fit against your demand before ordering. The drain on this unit is differential-pressure, which clears the bowl as the pressure difference across it builds; automatic (A) or manual (M) drains can be ordered instead. The 40 um element is standard, and code W gives 5 um where finer filtration is needed. The fitted round gauge reads psi, while an embedded square gauge and MPa or bar scales are the alternatives. The thread on this code is G (BSPP), with PT as the standard and NPT orderable, and the mounting bracket is included.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand, and we will confirm the sizing against the datasheet curves before you order.
The L in GFR20008LC2GK marks the low-pressure regulator type. AirTAC does not publish an exact regulating range for this variant, so tell us the pressure you need to hold and we will confirm from the datasheet whether it fits. The rest of the code decodes directly: G1/4 port, 40 um element, differential-pressure drain, round psi gauge, check valve fitted, bracket included.
