The AirTAC GFR20008LC2WGK AirTAC Filter Regulator G1/4, 5 um is a genuine G-series filter regulator: water separation, 5 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 series combines water and particulate filtration with pressure regulation in a single body. This configuration, GFR20008LC2WGK, is the size 200 unit with a G1/4 (1/4 inch) G-thread port, a 5 um filter element (the W grade, finer than the 40 um standard), a differential-pressure drain, and the low-pressure regulator type. It is fitted with an external round gauge scaled in psi, a reverse (check) valve, and includes a mounting bracket. The bowl on this size is polycarbonate (PC). Maximum working (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 inch, and options for automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and other datasheet figures 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Filtering and regulating supply air for the guns and air-assisted applicators on a spray booth or finishing line, with the 5 um element catching fine particulate before it can reach the finish.
Feeding filtered, regulated air to the small cylinders and actuators on a carton-sealing or labelling conveyor, with the fitted reverse valve part of the downstream circuit.
Conditioning compressed air for laboratory pneumatic instruments and test rigs that run on the low-pressure regulator type, where fine 5 um filtration is specified ahead of the device.
Size 200 with a G1/4 port is the compact step of the GFR range; step up to 300, 400 or 600 when the application needs a larger port and more flow. This unit carries the 5 um (W) element rather than the 40 um standard, a differential-pressure drain (automatic and manual drains are orderable alternatives), a round gauge scaled in psi (embedded square gauges in MPa, psi or bar are the alternative), and a reverse/check valve. The thread here is G (BSPP); PT is the AirTAC standard thread and NPT is also a catalogue option. A mounting bracket is included.
As a low-pressure regulator type, this unit's adjustment range is not published in our data, so we do not quote a figure. AirTAC publishes flow only as curves, not a single rated number, so ask us to confirm sizing - including the regulator range - against your application before ordering.
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 GFR flow as curves rather than a single rated number, so we do not quote a figure here. Send us your application details and we will confirm the flow and other datasheet figures for this exact model on request.
The L marks the low-pressure regulator type. Its exact adjustment range is not published in our data, so we confirm it on request rather than quoting a figure. Everything else about the unit - G1/4 port, 5 um element, differential-pressure drain, round psi gauge, check valve and included bracket - is decoded directly from the code.
