The AirTAC GFR600C20LJC2WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20LJC2WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body. This size 600 unit carries a 3/4 in NPT port, a 5 um filter element (code W), a differential-pressure drain on the bowl, and a reverse/check valve fitted. It is the low-pressure type (code L), and the external round gauge supplied is scaled in psi. At size 600 the bowl is aluminium alloy. No mounting bracket is included with this code.
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, filter grades of 40 um (standard) or 5 um (W), a choice of differential-pressure, automatic or manual drain, gauge styles and scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

On a stamping or assembly press fed from a plant air ring main, this unit filters incoming compressed air and holds a reduced, stable supply pressure to the press cylinders, with the psi gauge giving operators a local setpoint readout.
On a bottling or cartoning line, the 3/4 in port serves a conveyor section's air cylinders and air-actuated diverters, while the 5 um element helps keep fine particles out of the control valves downstream.
Feeding a bank of quarter-turn pneumatic valve actuators at a treatment works, the unit cleans the air supply and regulates it to the actuators' operating pressure, with the check valve holding the circuit if supply pressure is interrupted.
Step up through sizes 200, 300, 400 and 600 as your port size and air demand grow; this code is already at the top of the range with a 3/4 in NPT port. The 5 um element (W) suits points of use that need finer particle removal than the 40 um standard; the differential-pressure drain bleeds collected condensate automatically as pressure differential builds. The round gauge is ordered in MPa, psi or bar scales - this unit carries psi. Thread is NPT here; PT (standard) and G are the other catalogue options. A bracket is optional and not fitted on this code. Flow is published as curves, not a single rating, so send us your flow and pressure conditions 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 series as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and required flow and we will confirm sizing against the datasheet on request before you order.
The W in the code specifies the finer 5 um filter element instead of the 40 um standard, and C2 specifies an external round gauge scaled in psi (MPa and bar scales are the other options). The L code marks it as the low-pressure regulator type - its adjustment range is not published on the sheet we work from, so ask us to confirm it for your setpoint.
