The AirTAC GFR600C20ALF3TK 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.
GFR600C20ALF3TK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 configuration has NPT3/4 ports, a 40 um standard filter element, an automatic drain and the low-pressure regulator type. It is fitted with an embedded square gauge reading in bar, a reverse/check valve and a mounting bracket, and the size-600 bowl is aluminium alloy. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm 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. 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.

Regulated low-pressure air for pneumatic clamps and fixtures on machining centres, where the filtered supply protects clamp cylinders and the low-pressure setting holds workpieces without over-clamping.
Clean, regulated air for diverters, pushers and gripper cylinders on a packaging conveyor, with the automatic drain clearing condensate between shifts without operator attention.
Low-pressure regulated air for laboratory automation and test rigs, where the bar-scale square gauge gives a direct local reading and the 40 um element guards sensitive instruments.
Size 600 is the largest GFR frame, so step through 200/300/400/600 against the port and flow your line needs; this unit takes NPT3/4. Drain choice matters: automatic drains condensate on its own, manual needs operator attention, and the differential-pressure default bleeds as the pressure drop builds. The 40 um element is standard; specify W for 5 um where downstream equipment needs finer filtration. The gauge here is the embedded square type reading bar; an external round gauge and MPa or psi scales are options. Thread is NPT on this code, with PT as the standard and G available to order, and the mounting bracket is included. Note this is the low-pressure regulator type, so its setting range differs from the standard type. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow data from the datasheet on request.
The L code in GFR600C20ALF3TK marks the low-pressure regulator variant, intended where the working pressure sits below the standard type's range. The catalogue does not publish an exact setting figure for this variant, so we confirm it on request before you order.
