The AirTAC GFR60020ALJNTK 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 automatic 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 GFR60020ALJNTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This configuration is built around a 3/4 in NPT port, carries the standard 40 um filter element, and drains condensate automatically, so the bowl keeps clearing water without anyone opening it. The regulator is the low-pressure type, a reverse/check valve is fitted to hold downstream pressure if the supply dips, and no gauge or mounting bracket is included. As a size-600 unit, its bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, manual, automatic or differential-pressure drains, an optional 5 um element (code W), gauge choices and G (BSPP) or NPT thread variants. Rated inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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". |
| A | Drain: Automatic 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.

Conditions and regulates the low-pressure supply feeding clamping and actuation circuits on a trim line, while the automatic drain keeps condensate out of the valves and cylinders downstream.
Delivers filtered, regulated air to fixture clamps in a machining cell; the fitted reverse/check valve helps hold clamp pressure if the shop supply dips mid-cycle.
Prepares the air supply for sorting and diverter cylinders on a packaging conveyor, with the automatic drain handling the condensate that collects along long runs of line.
Pick the size step (200/300/400/600) and port against the air demand of your line; this unit sits at the top of the range with a 3/4 in NPT port. Choose the drain to suit access: automatic here, with manual and differential-pressure available as order options. The 40 um element is standard; specify code W for the 5 um grade where finer filtration is needed. Thread is NPT on this model, with G (BSPP) and PT variants to order, and brackets are optional. Flow is published as curves, not a single rating, so send us your demand figures 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.
Flow for the GFR600 series is published as curves, not a single rated figure, so we do not quote a number here. Send us your line demand and operating pressure and we will confirm the sizing from the AirTAC datasheet on request.
The N in the code means no gauge is fitted, and the L means the regulator is the low-pressure type. Gauge variants with square or round dials and MPa, psi or bar scales are available in the series to order; ask us and we will confirm the right option code.
