The AirTAC GFR20008MLJF3WTK AirTAC Filter Regulator NPT1/4 5um 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 GFR20008MLJF3WTK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single compact body. This configuration has a 1/4 in NPT port, a 5 um filter element, a manual drain on the PC (polycarbonate) bowl, a fitted reverse/check valve, and an embedded square gauge reading in bar. It is the low-pressure type, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for thread (PT is the standard; G and NPT are catalogue options), drain type, filter grade, gauge style and scale. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing. Because flow is published as curves rather than a single rating, we confirm datasheet and flow 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.
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Filtered, regulated air at a 1/4 in feed for small pneumatic grippers and cylinders on PCB handling and small-part placement stations, where the 5 um element helps protect delicate valve internals.
Point-of-use supply for labelling heads, carton tuckers and sealing cylinders along a packaging conveyor, with the bar-scale gauge letting operators set and check line pressure at a glance.
Conditioning at the bench for lab rigs and pilot test stands that need clean, regulated low-pressure air, with the manual drain giving supervised, controlled water removal.
The real choices in this family are the size and port step, the drain type, the filter grade, the gauge and its scale, and the thread. This unit is size 200 with a 1/4 in NPT port, suited to smaller lines; step up to 300, 400 or 600 for larger ports and more flow. The 5 um element (code W) suits air feeding finer components, while 40 um is the standard grade. The manual drain means water in the bowl is released by hand during routine checks; automatic or differential-pressure drains suit unattended installations. The embedded square gauge reads bar, with MPa and psi scales available. PT is the standard thread, with G (BSPP) and NPT as catalogue options, and the J code means no bracket is fitted. Flow is published as curves, not a single rating, so 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 rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this exact configuration on request.
The M code in this model specifies a manual drain: water collected in the PC bowl is released by hand during routine checks. If the unit will sit in an unattended position, the same GFR200 size is available with an automatic or differential-pressure drain - we can quote the variant that matches your installation.
