The AirTAC GFR60020MJF2WGK AirTAC Filter Regulator G3/4, 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 PT3/4" 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 GFR60020MJF2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 (BSPP) port, a 5 um filter element (the finer of the two published grades), a manual drain for the aluminium alloy bowl, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is removed. Maximum inlet pressure is 1.0 MPa (145 psi); the standard regulator covers 0.05-0.9 MPa (7-130 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge scale options, and PT, G or NPT threads. Flow for this family is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| 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. |
| 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.

Installed at the take-off point of a factory compressed-air ring main, it filters water and scale from the 3/4 inch branch line and holds a steady regulated pressure for the tools and actuators fed from it.
Feeding the air cylinders on a carton-sealing or palletising conveyor, the 5 um element protects valve spools from particulate while the regulator keeps cylinder speed consistent shift to shift.
Mounted on a skid of pneumatic quarter-turn actuators, it delivers clean, regulated air and the built-in check valve holds the actuator's downstream pressure if the upstream supply is shut off for maintenance.
Start with the port and size step: size 600 is the largest GFR frame and carries a 3/4 inch port, so match it against the pipe size and the flow your line actually needs - we can confirm the published flow curve against your demand before you order. The 5 um (W) element suits downstream equipment that needs finer filtration 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 mechanism. The square gauge is set to psi here (MPa and bar scales are alternatives), and the K code adds a reverse/check valve. Thread is G (BSPP) in this code; PT and NPT versions are order options. This J-coded unit comes without a mounting bracket.
Because rated flow is published as curves rather than a single number, we do not quote a figure here - send us your application details and we will confirm sizing from the datasheet before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream set pressure and required air demand, and we will confirm the sizing against the datasheet curve on request before you order.
The manual drain means an operator opens the bowl drain during routine checks instead of relying on an automatic or differential-pressure mechanism - a simple choice where checks are already scheduled. The W-coded 5 um element is the finer of the two published grades versus the 40 um standard, suited to downstream valves and cylinders that need cleaner air. This unit also has an aluminium alloy bowl (standard on size 600), a psi square gauge, and a fitted reverse/check valve.
