The AirTAC GFR60020LNTK 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 GFR60020LNTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit has 3/4 in NPT ports, the standard 40 um filter element, a differential-pressure drain and a low-pressure regulator, with a reverse/check valve fitted (code K). The aluminium alloy bowl suits this larger frame, and a mounting bracket is included. No gauge is fitted (code N), so add a separate gauge if you need local pressure indication.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for manual or automatic drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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. |
| (blank) | Mounting bracket included. |
| 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.

Filtered, regulated supply for the filler-head and capper cylinders on a bottling line, with the fitted reverse/check valve where back-flow protection matters on the drop leg.
Conditioned air feeding the directional-control valves that index cartons and divert product on a packaging conveyor, with the 40 um element guarding the valve seats.
A low-pressure regulated branch on a laboratory or pilot test rig, where the operator sets a reduced supply pressure for sensitive pneumatic fixtures and gauges.
The real choices on this code: the size 600 frame with 3/4 in NPT ports suits lines plumbed at 3/4 in and the larger end of the range; the 40 um element is the standard grade, with a 5 um W element available on other codes; the differential-pressure drain is the default, with automatic (A) and manual (M) variants in the family; and the low-pressure regulator is intended where setpoints sit below the standard type's range - the exact range is not published, so confirm it with us. NPT is ordered as the T option; PT is the catalogue standard and G (BSPP) is also available. A bracket is included. Flow is published as curves, not a single rating, 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-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and required flow and we will confirm from the datasheet whether the size 600 unit at 3/4 in NPT suits your application.
No. The N in the code means no gauge is fitted. Across the GFR family you can order a gauge - embedded square or external round - with a scale in MPa, psi or bar. Ask us to quote a code with the gauge option if you need local downstream indication.
