The AirTAC GFR60020LC1TK 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 GFR60020LC1TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is built with a 3/4 in NPT port, a 40 um standard filter element, a differential-pressure drain on the aluminium alloy bowl, and the low-pressure regulator variant. It includes a round MPa pressure gauge, a reverse/check valve (code K) and a mounting bracket.
This is a genuine AirTAC part. The GFR range covers sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in; PT is the standard thread and G or NPT are catalogue options, with NPT specified here. Maximum 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.

|---|---|
| 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 filtered, regulated air to the cylinder and valve manifold on a carton-forming packaging line, where the low-pressure regulator holds a steady setting for the machine's actuators and the 40 um element protects the valves from water and debris.
Conditioning the air supply to spray or dosing heads on a coating line: the 40 um element strips water and particles from the plant air before the low-pressure regulator feeds the applicator circuit at the setting the process needs.
Serving as the filter-regulator stage in a 3/4 in air-preparation panel on a plant air distribution leg, with the fitted reverse/check valve, round MPa gauge and differential-pressure drain built into the aluminium alloy bowl assembly.
Size and port step up with flow demand: this is the 600 size with a 3/4 in NPT thread (PT is standard; G and NPT are catalogue options). Drain choices are differential-pressure (this unit), automatic (A) or manual (M); the filter element is 40 um standard or 5 um with code W. The gauge and its scale (MPa, psi or bar), the low-pressure regulator type (L), the reverse/check valve (K) and the bracket are all decodable from the code. Because flow is published as curves rather than a single rated figure, send us your application details 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your required flow and pressure and we will confirm the datasheet curve for the GFR600 at 3/4 in NPT before you order.
The L marks the low-pressure regulator variant rather than the standard type. Its exact adjustment range is not published in the materials we hold, so we confirm it on request. Everything else decodes normally: 600 size, 3/4 in NPT port, 40 um element, differential-pressure drain, round MPa gauge, reverse/check valve and included bracket.
