The AirTAC GFR600C20ALF2TK AirTAC Filter Regulator NPT3/4 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 See datasheet 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 AirTAC GFR600C20ALF2TK is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that clears collected condensate without manual attention, and a low-pressure regulator type. The embedded square gauge reads in psi, a reverse/check valve is fitted, and the size 600 bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, manual or automatic or differential-pressure drains, an optional 5 um element (code W), and gauge scales in MPa, psi or bar. 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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 pneumatic clamps and vises on a machining cell, where the automatic drain keeps condensate out of the clamp cylinders between operator checks.
Conditioning the air supply to spray guns in a paint line, removing water and particles ahead of the gun while the regulator holds a steady set pressure for consistent atomisation.
Supplying the cylinder-driven pushers and diverters on a packaging conveyor, with the reverse/check valve holding the downstream circuit if the upstream supply drops.
Size 600 with a 3/4 in port sits at the top of the GFR range; step down to 200/300/400 if your line flow is modest, since port and body size step together. Drain choice matters: automatic (this unit) suits points that are checked infrequently, manual suits attended stations, and the differential-pressure default empties only when the pressure drop warrants it. The 40 um element is standard; specify code W for 5 um where finer particulate removal is needed. The square gauge here reads psi; MPa or bar scales are orderable, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are catalogue options ordered by suffix, as on this NPT unit. As a low-pressure type, the adjustment range differs from the standard regulator - confirm the set pressure with us before ordering. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number. Tell us your line flow and working pressure and we will confirm the sizing from the datasheet on request.
The L code selects the low-pressure regulator variant instead of the standard one. The exact adjustment range for this low-pressure configuration is not published in the material we hold, so confirm your required set pressure with us before ordering. Max inlet pressure remains 1.0 MPa (145 psi) and the unit operates from -5 to 70 C, non-freezing.
