The AirTAC GFR20008MLJF2WGK 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 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 combines water-and-particulate filtration with pressure regulation in a single body, so one G1/4 (1/4 in) connection cleans the air and sets its pressure in the same step. This configuration is the low-pressure type with a 5 um filter element (code W), a manual drain bowl in PC (polycarbonate), an embedded square gauge scaled in psi, and a reverse/check valve fitted; it is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and choices of drain type, filter grade, gauge scale and thread (PT standard; G and NPT are order options). Flow is published as curves rather than a single rating, so ask us to confirm the sizing and the low-pressure regulation range for your application before ordering.

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". |
| 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). |
| F | Gauge shape: Square. 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.

On a small assembly press or clamping fixture fed at low set pressure, this unit filters the shop air to 5 um and holds a steady regulated supply, with the check valve keeping the circuit charged during brief supply dips.
Fitted at the air inlet of a cartoning or wrapping machine, the GFR200 cleans water and particles from the supply and lets operators set the working pressure locally, reading the embedded psi gauge at the machine.
For bench-scale process rigs and pilot lines that run at reduced pressures, the low-pressure regulator type with 5 um filtration conditions the compressed air feeding valves, actuators and sample-handling cylinders.
Start with the port and size: this unit is GFR200 with a G1/4 (1/4 in) port, the smallest step in the range, so step up to GFR300/400/600 if your line needs larger ports and more flow. The 5 um element (code W) suits points of use that need finer particulate capture than the 40 um standard; the manual drain means an operator opens the bowl drain during checks rather than relying on an automatic or differential-pressure drain. The embedded square gauge is scaled in psi (MPa and bar scales are available), the reverse/check valve holds downstream pressure if the supply drops, and the low-pressure type is intended for lower set pressures - confirm the exact range with us. Thread is G (BSPP); PT is the standard and NPT can be ordered, and a mounting bracket can be added if this no-bracket version does not suit your panel. Because flow is published as curves, not a single rating, 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 flow for this series as curves rather than a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and the equipment you are feeding, and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: collected water is released by opening the bowl drain during routine checks, instead of draining automatically. The L specifies the low-pressure regulator type, intended for lower set pressures than the standard version; its exact adjustment range is not published, so confirm it with us before ordering.
