The AirTAC GFR600C20AJC1TK 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 GFR600C20AJC1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This 600-size unit is fitted with a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, the standard 40 um filter element, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). A round external pressure gauge scaled in MPa is included, and a reverse (check) valve is fitted. The aluminium alloy bowl suits the 600 frame, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature 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 in to 1 in, and options including manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, brackets, and a low-pressure regulator type. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and flow data 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. 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.

Installed at a 3/4 in drop from the plant air main, it removes pipeline water and rust and holds a steady regulated pressure to the cell. The automatic drain handles condensate on lines that are not visited every shift.
Feeding cylinders and air controls on a conveyor line, the unit cleans the supply and keeps actuator pressure constant through the day. The check valve holds the downstream setting if upstream supply dips.
On a machine-tool clamping circuit, the 40 um element screens particles ahead of the regulator, and the MPa-scaled gauge lets the setter read and hold the clamp pressure directly at the fixture.
Choose the size and port step against the air demand of the circuit: this unit is 600 size with a 3/4 in NPT port, the largest frame in the GFR range. Select the drain to suit access: automatic (as here) suits installations that are not checked daily; manual suits attended points; differential-pressure drain is the catalogue default. Select the filter grade: 40 um is standard for general air preparation, 5 um (code W) where finer particulate removal is needed. Gauge scale can be MPa, psi or bar, embedded square or external round. Thread is PT as the catalogue standard, with G (BSPP) and NPT as orderable options; this unit is NPT. Bracket (J = none) and reverse/check valve (K = fitted) complete the code. Because flow is published as curves rather than 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-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow data from the datasheet for this 600-size, 3/4 in NPT unit before you order.
Drain type is a real choice on GFR filter regulators: automatic (A) ejects condensate by itself, manual (M) needs an operator, and differential-pressure drain is the catalogue default. The trailing K in GFR600C20AJC1TK means a reverse (check) valve is fitted; T is the NPT thread, C1 is the round gauge with MPa scale, and J means no mounting bracket.
