The AirTAC GFR600C20LJF2T AirTAC Filter Regulator NPT3/4 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 AirTAC GFR600C20LJF2T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge on a psi scale, and the low-pressure regulator type. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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.

Feeds and regulates the air to clamping cylinders on a CNC fixture line, where the low-pressure regulator type holds a gentle, consistent clamp force and the 40 um element keeps water and chips-born debris out of the valves.
Sits at the inlet of a cartoning or wrapping machine's air manifold, filtering the shop supply and setting a stable, moderate working pressure so actuators and grippers cycle predictably through a full shift.
Installed at a 3/4 in branch drop feeding an assembly cell, conditioning the main line air and letting each cell set its own working pressure independently of the compressor room, with the psi gauge giving operators a local readout.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range, suited to lines with substantial air demand; step down to 200/300/400 if your flow is modest. This unit is the low-pressure regulator type, so confirm the set pressure you need suits that variant. The 40 um element is the standard grade; order the W variant if you need 5 um. Drain is differential-pressure; automatic (A) and manual (M) drains are available in the family. The square gauge here reads psi; MPa and bar scales are options, and an external round gauge can be specified. Thread is NPT; PT and G are catalogue alternatives. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
The J in the model code means no mounting bracket is included; bracketed versions are available in the family. The embedded square gauge on this unit reads psi; MPa and bar scales, and an external round gauge, are catalogue options.
