The AirTAC GFR60020LJNTK AirTAC Filter Regulator 3/4 in NPT 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 GFR60020LJNTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit has 3/4 in NPT ports, a 40 um standard filter element, a differential-pressure drain and a low-pressure regulator, with a reverse/check valve fitted and no gauge or mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The aluminium alloy bowl is specific to the 600 frame.
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, PT as the standard thread and G or NPT to order, plus a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration and optional gauges. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Feeding regulated air to pneumatic clamps and air tools on an automotive trim line, with water and swarf knocked out of the plant supply before it reaches the actuators.
Supplying filtered, gently regulated air to gate cylinders and reject pushers on a packaging conveyor, where the low-pressure regulator type keeps delicate product handling steady.
Conditioning the shop-air feed to a laboratory or test bench, filtering out water and particles and holding a low regulated pressure for sensitive bench instruments.
Size and port scale with air demand: this 600 unit steps up to 3/4 in NPT ports for larger air lines. The remaining choices are the drain type (differential-pressure as here, or automatic or manual), the filter grade (40 um standard, 5 um with code W) and the thread (PT standard; G and NPT are order options). Gauge and scale are selectable on other variants - this code carries no gauge - and the low-pressure regulator type suits circuits that run below standard setting ranges. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the flow from the GFR600 datasheet on request.
No. The N in the code means no gauge is fitted. Gauge versions of the GFR series are available with an embedded square gauge or an optional external round gauge, in MPa, psi or bar scales - ask us for the equivalent code.
