The AirTAC GFR20008MJF3WTK AirTAC Filter Regulator NPT1/4, 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 GFR20008MJF3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body, so one unit does the job of a filter and a regulator. This size 200 configuration has a 1/4 in NPT port, a manual drain bowl in polycarbonate, a fine 5 um filter element, a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), an embedded square gauge with a bar scale, and a built-in reverse (check) valve that holds downstream settings if upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um fine filtration, and gauge scales in MPa, psi or bar. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard 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.

Point-of-use conditioning on a CNC machining centre: the 5 um element and regulation protect solenoid valves and air bearings on the spindle and tool-changer circuit, and the check valve holds the set pressure through upstream dips.
Feeding cylinders and grippers on a carton packaging line: clean, regulated air at a stable setpoint keeps pick-and-place strokes consistent through the shift, with the manual drain emptied during scheduled washdowns.
A dedicated takeoff for spray guns and air-assisted applicators in a finishing booth: the fine 5 um grade and steady regulated pressure support finish quality, and the bar-scale gauge lets operators verify the setpoint at a glance.
Size and port are the first choice: the G-series steps through sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand with margin - we can check the curve against your application before you order. This code already fixes the rest of the configuration: manual drain (simplest to service, and it widens the regulation range to 0.05-0.9 MPa), a 5 um fine element where the 40 um standard grade is not clean enough, a square gauge with a bar scale (MPa, psi and bar scales are available), a fitted reverse/check valve, NPT threads (G/BSPP is the other catalogue option; PT is the standard thread), and no mounting bracket. If you need a bracket, a different drain, grade or scale, those are decodable options on the same series.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number here. Send us your line pressure, port size and air demand and we will confirm the right size from 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 the GFR series as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line pressure, port size and air demand, and we will confirm the flow from the datasheet on request and check the sizing against your application before you order.
The M in the code selects a manual drain: condensate collected in the polycarbonate bowl is released by operating the drain by hand as part of routine maintenance, instead of automatically. With a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi). If you would rather not rely on manual draining, automatic and differential-pressure drain versions are available in the same series.
