The AirTAC GFR600C20AJC2WK AirTAC Filter Regulator PT3/4, 5 um 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 GFR600C20AJC2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 3/4 in PT thread, carries a 5 um filter element (the finer optional grade; 40 um is standard), and drains condensate automatically, so the bowl does not need manual draining on a set schedule. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an external round gauge scaled in psi is fitted so the set pressure is visible at the unit. A reverse/check valve is included to hold downstream pressure if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge type and scale, and optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Installed at the 3/4 in take-off feeding a plant floor of air tools and actuators, this unit cleans the supply to 5 um and holds a regulated working pressure, with automatic drainage keeping condensate off the distribution network.
On a machining cell where clamps and a pneumatic press need a stable, repeatable set pressure, the psi-scaled gauge lets the setter dial in the clamping force, and the check valve holds the circuit if the main supply dips.
Feeding the cylinders and air jets on a packaging or conveyor line, the 5 um element protects directional valves from particulate while the regulator keeps actuation speeds consistent, and the automatic drain suits equipment that runs unattended.
Size 600 with a PT3/4 port sits at the top of the GFR range, so start by matching the port and the expected air demand to your line size; if your consumption is well below what a 3/4 in line carries, a smaller GFR size may be the more economical choice. This unit already specifies the finer 5 um element - choose it where downstream valves, cylinders or instruments are sensitive to finer particulate; the standard grade is 40 um. The automatic drain suits installations that are not visited daily; a manual drain is the alternative where an operator is on site. The fitted round gauge reads in psi; MPa and bar scales are also available. PT is the standard thread, with G (BSPP) and NPT as order options, and this configuration is supplied without a mounting bracket.
Because flow for the GFR series is published as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow before you order.
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 rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line pressure and the air demand of your equipment and we will confirm the datasheet flow curve and check the sizing for your application on request.
Both are decoded from the model code. The A position selects the automatic drain, which expels collected condensate without an operator, and the W position selects the optional 5 um filter element instead of the 40 um standard grade - a good choice when downstream valves, cylinders or instruments are sensitive to finer particulate. A manual-drain, 40 um version of the same size 600 unit is available if that suits your installation better.
