The AirTAC GFR20008MLJC3WT AirTAC Filter Regulator 1/4 in NPT, 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 series combines water and particulate filtration with pressure regulation in a single body. This unit, GFR20008MLJC3WT, is the size 200 configuration with a 1/4 in NPT port, a 5 um filter element (code W), a manual drain, and the low-pressure regulator type. A round gauge scaled in bar is fitted so the set pressure can be read directly at the unit, and the polycarbonate bowl allows visual checks of accumulated condensate. No mounting bracket is included with this code. 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. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drain type (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this family is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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). |
| C | Gauge shape: Round. 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Set a reduced, stable supply pressure for atomizing air to spray guns in a finishing booth, with the 5 um element helping keep fine particles and moisture out of the air reaching the finish.
Feed clamp cylinders on a machining fixture where a lower set pressure is wanted to avoid marking delicate workpieces, with the fitted bar gauge giving a direct pressure readout at the machine.
Regulate filtered air to carton-sealing and labeling cylinders on a packaging conveyor, with the manual drain allowing the bowl to be purged during scheduled line changeovers.
The real choices on this family are the size and port step, the drain type, the filter grade, the gauge, the thread and the bracket. Size 200 with a 1/4 in port is the compact end of the range; step up to 300, 400 or 600 for larger ports and greater flow capacity, remembering that flow is published as curves, not a single rating. The 5 um element (code W) suits circuits that need finer particulate capture than the 40 um standard, and the manual drain means an operator drains the bowl as part of a routine. This code is the low-pressure regulator type with a round bar gauge and no bracket; the embedded square gauge, other gauge scales (MPa/psi/bar), a mounting bracket, and PT or G threads are orderable alternatives. Because flow figures are curves, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow curves and datasheet figures on request before you order.
This code is the low-pressure type, and the exact adjustment range for that variant is not published in our source material, so we confirm it from the datasheet on request. What is published: maximum inlet pressure is 1.0 MPa (145 psi), and standard-type GFR units with manual drain adjust 0.05-0.9 MPa (7-130 psi).
