The AirTAC GFR600C20LJF2TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20LJF2TK 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 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain in an aluminium alloy bowl, a low-pressure regulator type, an embedded square gauge reading in psi, and a built-in reverse/check valve; no mounting bracket is included. It is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

Point-of-use conditioning for the pneumatic cylinders and clamp actuators on a packaging line's case-sealing station, with the check valve holding the regulated circuit if upstream supply dips.
Filtered, regulated air for the gate and pusher cylinders that divert product between conveyor lanes, with the 3/4 in port feeding a manifold serving several valves at one station.
Conditioning the air feed to valve positioners and air-operated control valves on a process skid that runs at reduced working pressure, using the low-pressure regulator type.
Start with the port step: this unit is the size-600 frame with a 3/4 in NPT port, the largest in the GFR range, so step down to GFR200/300/400 if your line is smaller - match the frame to the flow your circuit needs and let us verify it against the catalogue curves. Choose the drain to suit access: this model uses the differential-pressure drain (the default); automatic drain (code A) suits unmanned installations and manual drain (code M) suits infrequent servicing. Filtration is the standard 40 um here; specify code W for 5 um where finer particle removal is needed. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread is NPT on this unit, with PT (standard) and G available to order. Note this is the low-pressure regulator type - its exact adjustment range is not published, so confirm it with us. No mounting bracket is included; brackets are optional on the GFR range.
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 l/min, m3/h or SCFM number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The differential-pressure drain is the default on the GFR range: it bleeds condensate automatically as flow passes through the unit, with no operator attention. If you prefer an automatic drain for unmanned equipment or a manual drain for infrequently serviced points, the same size-600 filter regulator is available with drain codes A or M - just ask us to quote the variant.
