The AirTAC GFR60020LJF2WG 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 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 GFR60020LJF2WG is an AirTAC GFR-series filter regulator: it strips water and particulate from compressed air and holds a regulated downstream pressure in a single body. This size-600 unit is built with a G3/4 (3/4 inch) port, a 5 um filter element (the finer of the two published grades), and a differential-pressure drain, the default arrangement, which discharges collected condensate when airflow creates the pressure differential across the drain. The regulator is the low-pressure type, and the embedded square gauge reads in psi. At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket (code J). Working limits are 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, and square or external round gauges in MPa, psi or bar scales. Flow for this model is published as a curve rather than a single rated figure, so send us your operating conditions and we will confirm sizing and the full datasheet 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.

| 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. |
| 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. |

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.

Feeding low-pressure actuators on a bottling or canning line - clamp cylinders, hold-downs and diverters that run at reduced set pressures and need clean, water-stripped air at each drop.
Supplying an air-knife or nozzle blow-off station above a conveyor, where the regulator sets a stable reduced pressure for clearing dust, chips or moisture from product or packaging.
Regulating supply to process valves and small actuators on a skid or test bench that operate at low set pressures, with the 5 um element protecting pilot components from particulate.
Size and port step up with flow demand: 600 is the largest GFR size, here with a G3/4 port in G thread (PT is the standard thread; G and NPT are order options). Choose the drain to match your maintenance routine: differential-pressure as fitted here, automatic for unattended condensate removal, or manual where you want positive control. Filtration on this unit is the 5 um grade; 40 um is the standard element if your circuit does not need the finer filtration. The gauge is the embedded square type reading psi, with an external round gauge in MPa, psi or bar available as an option. This is the low-pressure regulator variant, and its exact adjustment range is not published, so confirm your set pressure with us before ordering. No mounting bracket is fitted (code J). Flow is published as curves rather than a single rating, so ask us to check the curve against your application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as performance curves, not a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curve on request.
The L in GFR60020LJF2WG marks the low-pressure regulator variant, selected for circuits that operate at reduced set pressures. The catalogue does not publish an exact adjustment range for this variant, so confirm your target set pressure with us before ordering. The rest of the code decodes as: G3/4 port, G thread, 5 um element, differential-pressure drain, square psi gauge, and no mounting bracket.
