The AirTAC GFR60020MLJF2GK AirTAC Filter Regulator G3/4, 40 um 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 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 GFR60020MLJF2GK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure with its low-pressure type regulator. This configuration is built for a 3/4 in G (BSPP) port, drains by hand through its manual drain, carries a fitted square gauge reading in psi, and includes a reverse/check valve. As a size 600 unit, the bowl is aluminium alloy, and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT/G/NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filter grades, gauge scale options, and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so we confirm datasheet figures 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.
| 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. |
| (blank) | Filtering grade 40 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 3/4 in distribution line serving a production hall, the unit strips water and chips from the compressed air and holds a reduced, stable supply pressure for the whole cell.
On a welding fixture with air-operated clamp cylinders, the filter regulator cleans the supply and regulates it down to the clamping pressure, with the psi gauge giving operators a visible setpoint and the check valve holding the circuit if supply dips.
On a skid of air-operated process valves, the unit conditions the instrument air and regulates it to the actuator pressure range, with the manual drain letting maintenance staff clear accumulated condensate during scheduled rounds.
Start with size and port: the 600 frame with a 3/4 in G port is the largest step in the GFR range, so match it against the air demand of the circuit rather than pipe size alone. Choose the drain to suit access: this unit is manual drain (drain by hand at the bowl), while automatic and differential-pressure drains suit installations that are not checked daily. The 40 um element is the standard grade; specify W for the 5 um option where finer filtration is needed. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is G here, with PT standard and NPT orderable. No bracket is fitted (code J); brackets are optional on other codes. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application 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 this series as curves, not as a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code means the bowl drains by hand, which suits installations checked during routine maintenance. If the unit will sit unattended, the same GFR600 family is available with an automatic drain (code A) or a differential-pressure drain (blank), and this size 600 unit has an aluminium alloy bowl either way.
