The AirTAC GFR60020MLJF2WTK AirTAC Filter Regulator NPT3/4 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 GFR60020MLJF2WTK is a size-600 GFR filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built for 3/4 in NPT threads, carries the fine 5 um filter element (code W), drains by hand through its manual drain, and is the low-pressure (L) regulator type. The embedded square gauge fitted here reads in psi, and a reverse/check valve (code K) is fitted to hold downstream settings. The aluminium alloy bowl is standard at size 600, and no mounting bracket is included with the J code.
This is a genuine AirTAC part in the largest G-series size, which steps up from 200 through 300 and 400 to 600 for larger ports and higher flow. Across the GFR line you can choose port and thread (PT standard, with G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with W), gauge scale (MPa, psi or bar), bracket and reverse valve. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures against 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. 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.
| 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)). |
| 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. |
| 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. |
| 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.

Feeds clamp and fixture cylinders on a CNC machining cell, where the 5 um element keeps spool and seal surfaces clean and the regulator holds a steady low clamping pressure shift after shift.
Supplies regulated air to bagging and carton-sealing heads that run at reduced pressure, with the psi gauge letting operators set and verify the setting and the check valve holding it during supply dips.
Conditions and regulates the air feeding blow-off nozzles and air knives along a conveyor line, removing water and fine particles before the air reaches the nozzles on a 3/4 in main.
Size 600 with a 3/4 in port is the right step when your line's flow demand outgrows 1/2 in and smaller units - compare the published flow curves for size 600 against your consumption before committing. This unit is already specified with the choices that matter at order time: manual drain (simple and positive, but remember someone has to bleed the bowl), the 5 um fine element for air that feeds sensitive components, the low-pressure regulator type for circuits that sit below standard working ranges, a psi square gauge, a fitted check valve, and NPT threads. If you would rather have automatic draining, a 40 um element, a different gauge scale, G (BSPP) threads or a mounting bracket, those are available in the same GFR600 family - tell us and we will decode the right variant. We confirm flow and datasheet figures on request because AirTAC publishes them as curves, not a single rating.
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 GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line's air consumption and working pressure and we will confirm the sizing from the datasheet on request.
The M code means the aluminium bowl is emptied by hand, which suits installations that are checked regularly; automatic or differential-pressure drains are available in the same family if you cannot rely on manual bleeding. The L code marks the low-pressure regulator type, intended for circuits regulated below the standard range - its exact adjustment range is not published, so ask us to confirm it for your setpoint.
