The AirTAC GFR600C20ALJC2 AirTAC Filter Regulator PT3/4, 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 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 GFR600C20ALJC2 is an AirTAC GFR filter regulator: water-and-particulate filtration and pressure regulation combined in one body, so a single unit conditions the air and holds your set pressure downstream. This size 600 configuration carries a PT3/4 (3/4 in) PT thread, the standard thread for this series, with G (BSPP) and NPT available as order options. The automatic drain bleeds collected condensate from the aluminium alloy bowl without the bowl being opened, the 40 um standard element handles everyday particulate, and the low-pressure type regulator is fitted with an external round gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. No mounting bracket is included with this code and no reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with a choice of differential-pressure, automatic or manual drains, a 5 um element (code W) where finer filtration is needed, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before you order.

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.

Clean, moisture-drained air held at a reduced, stable pressure for clamps and fixtures on a machining cell, where the workholding needs gentler pressure than the main shop supply.
Filtered and regulated low-pressure air feeding the seal and hold-down cylinders on a carton or bag packaging line, with the automatic drain keeping condensate out of the valves.
Water and particle removal plus reduced, steady pressure at the drop to spray guns in a wood-finishing booth, where overpressure ruins finish quality and the psi gauge makes setting simple.
Choose the size and port against the air your line actually uses: 600 is the largest GFR frame, and here it carries a 3/4 in PT3/4 port, so step down to GFR300 or GFR400 if your piping and air demand sit lower. Drain type is a real decision: automatic (this unit) suits installations you cannot open regularly, manual suits attended stations, and the differential-pressure default suits lines with a steady pressure drop. The 40 um element is standard; specify code W for 5 um where finer filtration matters. Gauges can be the embedded square type or this external round type, in MPa, psi or bar scale, and threads can be ordered in PT, G (BSPP) or NPT; brackets are optional. Note that this is the low-pressure regulator type, so confirm the adjustment range against your set point. Because flow is published as curves rather than a single rating, ask us to confirm sizing from the datasheet 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 flow for the GFR series 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 and sizing from the datasheet before you order.
This code ends in L, which makes it the low-pressure type of regulator. The exact adjustment range for the low-pressure variant is not published in the material we hold, so tell us your set pressure and we will confirm suitability from the datasheet on request.
