The AirTAC GFR20008MLJC1WTK AirTAC Filter Regulator NPT1/4 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 unit, GFR20008MLJC1WTK, is the 200 size with 1/4 in NPT ports, a 5 um filter element (code W), a manual drain, and a low-pressure regulator fitted with a round MPa gauge. A reverse/check valve (K) is included and no mounting bracket is fitted. The polycarbonate bowl lets you see the condensate level, and the manual drain is emptied by hand.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, thread options PT (standard), G (BSPP) and NPT, drain choices of differential-pressure, automatic or manual, and 40 um or 5 um filtration. Max 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 the 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Feeding spray guns on a finishing line: the 5 um element strips water and particles that would spoil the finish, while the low-pressure regulator holds a gentle, steady setting at the gun.
Supplying sealing jaws and small pick-and-place cylinders on a packaging line, where a stable low-pressure setting keeps jaw force consistent and the manual drain is emptied during changeover.
Providing clean, finely filtered low-pressure air to instruments and pneumatic test rigs on a lab bench, with the round MPa gauge giving a clear local pressure readout.
Size the unit by the port and flow step: the 200 size with 1/4 in NPT ports suits lighter-duty lines, while the 300, 400 and 600 sizes carry larger ports for higher demand. This configuration has a 5 um element for finer air than the 40 um standard, a manual drain you operate by hand, and a low-pressure regulator with a round MPa gauge - confirm the exact setting range for the low-pressure type on request. The thread here is NPT; PT is the standard and G (BSPP) is also an order option. A reverse/check valve is fitted and no bracket is included, though a bracket is available as an option. Because flow is published as curves rather than a single rating, ask us to confirm sizing 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, not a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow from the GFR200 datasheet on request.
L marks the low-pressure regulator type, intended for settings below the standard range - the exact range is not published, so we confirm it on request. W marks the 5 um filter element, finer than the 40 um standard. In this code M is the manual drain, C1 the round MPa gauge and K the fitted reverse/check valve.
