The AirTAC GFR600C20AJC1WTK 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 GFR600C20AJC1WTK is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air and holds downstream pressure steady, with no lubricator in this family. This size-600 unit is built around a 3/4 in NPT port, carries the fine 5 um filter element (code W), and has an automatic drain (code A) that bleeds collected condensate from the bowl without manual attention. The bowl on size 600 is aluminium alloy. A round pressure gauge with MPa scale (code C1) is fitted for setting and monitoring output, a reverse/check valve (code K) is fitted, and this configuration ships without a mounting bracket (code J). Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, reverse/check valve, bracket and thread form (PT standard, G and NPT as order options). Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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 spray-booth drop lines where fine 5 um filtration protects paint finish from water and particulate, while the regulator holds a steady gun pressure through a full shift.
Supplying the pneumatic cylinders and grippers on a packaging conveyor, with the automatic drain handling condensate on a line that runs unattended and the check valve holding settings upstream.
Regulating supply pressure to workholding clamps on a machining centre, where stable downstream pressure keeps clamping force consistent part after part and the round MPa gauge lets operators verify the setting.
Work size and port first: the four GFR sizes (200/300/400/600) step up in port and flow capacity, and this unit sits at the top of the range with a 3/4 in NPT port, so match it against the air demand of the circuit it feeds. Then set the drain: differential-pressure (default), automatic, or manual - this configuration uses automatic drain, which suits unattended installations where nobody drains the bowl on a schedule. Filter grade is 40 um standard or 5 um (W) for finer protection; this unit carries the 5 um element. Choose the gauge style and scale (MPa, psi or bar) and whether a reverse/check valve is needed; this one has a round MPa gauge and the valve fitted. Thread is PT as standard with G and NPT as catalogue options - this unit is NPT. Bracket included or omitted (J) is also a choice; this configuration has no bracket. One honest note before ordering: flow for this series is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you commit.
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 the GFR series as performance curves rather than a single rated figure, so we do not quote one number here. Send us your application details and we will confirm the datasheet flow figures for this 3/4 in, size-600 unit on request before you order.
The A in the code means the bowl drains collected condensate automatically, which suits installations where nobody empties the bowl on a schedule. The GFR family is also available with manual drain or the differential-pressure default, and the regulator adjustment range depends on the drain type chosen: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, 0.05-0.9 MPa (7-130 psi) with manual drain.
