The AirTAC GFR60020LJC2TK AirTAC Filter Regulator NPT3/4 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 GFR60020LJC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit has a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain and the low-pressure regulator type. The aluminium alloy bowl suits this large frame, a round psi gauge is fitted, a reverse (check) valve is built in, and this configuration comes without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drain choices, gauge and scale options, and G or NPT thread variants to order. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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). |
| C | Gauge shape: Round. 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. |
| 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.

Regulates the reduced pressure that pneumatic clamps and swing cylinders on a fixture need, while the 40 um element keeps scale and pipe debris out of the clamp valves.
Feeds filtered, regulated air to positioners and pilot actuators on quarter-turn valves, with the built-in check valve helping hold the setting if the upstream supply dips.
Sits at the drop of a packaging line to filter and regulate air for low-pressure cylinders and air-driven guides, with the 3/4 in port feeding the main drop.
Choose the size by the port and flow your line needs: size 600 with a 3/4 in port is the large-flow frame in the GFR range, with 200, 300 and 400 stepping down. Drain choices are differential-pressure (this model), automatic (A) or manual (M); filter grade is 40 um standard or 5 um with code W. Gauge scales are available in MPa, psi or bar, and thread can be ordered as PT (the standard), G or NPT. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, required downstream pressure and air demand, and we will confirm the sizing from the datasheet on request.
The L in GFR60020LJC2TK marks the low-pressure regulator type, intended where the downstream setpoint sits lower than a standard regulator would normally serve. The exact adjustment range for this variant is not published in the sheet we work from, so ask us to confirm it against the datasheet before ordering.
