The AirTAC GFR600C20ALJC2K AirTAC Filter Regulator PT3/4 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 AirTAC GFR600C20ALJC2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT3/4 port with PT thread, a 40 um standard filter element, and an automatic drain that expels collected condensate without manual attention. It is the low-pressure type, intended for circuits set below standard regulator ranges, and it is supplied with an external round gauge scaled in psi plus a built-in reverse/check valve; no mounting bracket is included. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 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 inch, and options include manual or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges scaled in MPa, psi or bar, and G or NPT threads in place of PT. Flow figures for this family are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Conditioning and regulating supply air to a low-pressure clamping or forming circuit on a pneumatic press, where clean, moisture-reduced air at a controlled low setting protects cylinders and tooling.
Feeding filtered, regulated air to gripper and wrapper cylinders on a packaging conveyor, with the automatic drain handling condensate on a line that runs without an operator at the bowl.
Supplying water- and particle-filtered air at a reduced, stable pressure to spray guns or low-pressure applicators, where the round psi gauge gives a direct readout of the set pressure.
Start with the port step: size 600 with a PT3/4 port suits lines plumbed at 3/4 inch, and larger sizes carry more flow - match the size to the air demand of the circuit. Choose the drain next: this unit has an automatic drain, which suits unattended installations; manual and differential-pressure drains are available in the family. The 40 um element is standard here; specify the W code if the application needs the 5 um grade. Gauge scale is selectable (MPa, psi or bar) and this unit carries the external round gauge in psi. PT is the standard thread; G (BSPP) and NPT are order options. Brackets are optional on this configuration.
Flow for GFR units is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing against the datasheet 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 family as curves rather than a single rated figure, so no single number can be quoted here. Send us your required flow and working pressure and we will confirm the datasheet figures and check the sizing for your application before you order.
The L code marks the low-pressure variant of the GFR regulator section, intended for circuits set below the standard adjustment range. The exact adjustment range for this variant is not published in the material we hold, so ask us to confirm it on the datasheet. This unit also carries an automatic drain, a 40 um element, a round psi gauge and a reverse/check valve.
