The AirTAC GFR60020LJF2GK AirTAC Filter Regulator G3/4 Low-Pressure 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60020LJF2GK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds a regulated downstream pressure. This size 600 unit comes with a G3/4 port (G thread; PT is the standard, with G and NPT available as order options), the 40 um standard filter element, a differential-pressure drain, an embedded square gauge scaled in psi, a reverse/check valve, and the low-pressure regulator type. No mounting bracket is included (code J).
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and drain, filter-grade, gauge, thread and bracket options. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing. The size 600 bowl is aluminium alloy. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |

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.

Conditions and regulates the air feeding a press or clamping fixture that operates at reduced set pressures, with the low-pressure regulator type matched to the job and the check valve holding the downstream setting.
Sits at the drop feeding cylinders and actuators on a packaging line, stripping water and particles before they reach the valves while holding a steady regulated supply downstream.
Feeds the diverters, stoppers and lifters along a conveyor line, keeping moisture and debris out of the directional valves and giving the station a stable regulated pressure.
Match the size and port step to the air demand of the circuit: this is size 600 with a G3/4 port, the largest step in the G-series, for lines with the heaviest consumption. Drain type matters in use - the differential-pressure drain fitted here bleeds the bowl as air passes, while automatic drains without intervention and manual needs periodic draining; choose per access and duty. Filter grade is 40 um standard; specify code W for the 5 um element where finer protection is needed. The embedded square gauge on this unit reads psi, with MPa and bar scales and an external round gauge available as options. Flow is published as curves, not a single rating, so 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 the GFR series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, built for applications that run at reduced set pressures rather than the standard range. The exact adjustment range for this variant is not published in the material we hold, so ask us to confirm it on request. Everything else decodes normally: G3/4 port, 40 um filter, differential-pressure drain, psi square gauge and a fitted check valve.
