The AirTAC AirTAC GFR20008MJF3TK Filter Regulator 1/4 in NPT is a genuine G-series filter regulator: water separation, 40 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 GFR20008MJF3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single compact body. This size 200 unit is threaded 1/4 in NPT, carries a 40 um standard filter element, and has a manual drain bowl in PC (polycarbonate) that you empty by hand as part of routine service. The square embedded gauge reads in bar, the standard regulator covers 0.05-0.9 MPa (7-130 psi), and a reverse/check valve (code K) is fitted. It is supplied without a mounting bracket.
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, drain choices (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale choices, and G/NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. 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. |
| (blank) | Filtering grade 40 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 feeding the clamp cylinders on a machining centre fixture, with the check valve holding the set pressure against momentary upstream dips and the bar gauge giving the operator a direct setpoint readout.
A single filter regulator supplying the air cylinders that divert packages between conveyor lanes, with manual drain suited to a line that is walked daily and a 40 um element protecting the directional valves from scale and pipe debris.
Conditioned air for the sealing jaws and vacuum cups on a bagging machine, where the regulator sets the jaw pressure for different film thicknesses and the polycarbonate bowl shows accumulated water at a glance during shift checks.
Start with the port step: size 200 at 1/4 in NPT suits lighter-duty circuits, while sizes 300, 400 and 600 step up in port and flow capacity - match the size to the air demand of the machine rather than oversizing blindly. This unit has a manual drain, which is the economical choice where an operator walks the line and can bleed the bowl; choose automatic drain (code A) on inaccessible or unattended installations. The 40 um element is the standard grade for general plant air; specify the 5 um W option only where downstream equipment needs finer filtration. The embedded square gauge here reads in bar; MPa and psi scales are also available, and an external round gauge is optional. Thread is NPT on this code; PT (standard) and G are catalogue options. A bracket can be added if you want panel mounting.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated l/min or SCFM figure. Send us your application's air demand and we will confirm the correct 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 only as characteristic curves, not as a single rated figure, so we do not quote a rated l/min, m3/h or SCFM number. Send us your application's air demand and line pressure and we will confirm the sizing from the datasheet on request before you order.
This unit's bowl (code M) empties only when someone opens the drain by hand, so it needs to be bled as part of routine checks. It is the right choice where the regulator sits in an accessible spot on a machine that is serviced regularly. For unattended or hard-to-reach positions, ask about the same unit with an automatic drain (code A) or the differential-pressure drain default.
