The AirTAC GFR600C25LJF1TK AirTAC Filter Regulator 1 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 GFR600C25LJF1TK is a filter regulator: one body removes water and particulate from compressed air and regulates the downstream pressure. This size 600 unit is built for 1 in NPT threads, carries the standard 40 um filter element, and drains condensate by differential pressure. The bowl on size 600 is aluminium alloy. The regulator is the low-pressure type, a square pressure gauge graduated in MPa is fitted, and a reverse (check) valve is built in. 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 ports from 1/8 to 1 in, and options include 5 um filtration (code W), automatic or manual drains, gauge scales in psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Supplies filtered, regulated air to swing clamps and risers on a CNC fixture, with the built-in check valve blocking reverse flow in the supply line and the low-pressure regulator holding the gentle setting the clamps need.
Feeds carton erectors and low-pressure cylinders on a packaging line, dropping plant air to the set pressure the actuators require while the 40 um element keeps rust and pipe scale out of the machine's valves.
Runs the diverters and stopper gates on a sorting conveyor, where the low-pressure regulator holds a light setting for the gate cylinders and the differential-pressure drain clears condensate carried in from the main line.
Choose the size and port against the air your line actually uses: this is the largest GFR size, with a 1 in NPT connection. Pick the drain to match attendance: the differential-pressure drain on this code needs no day-to-day setting, an automatic drain suits unattended points, and a manual drain suits attended ones. The 40 um element is standard; specify W for 5 um where finer filtration matters. The fitted square gauge reads in MPa, with psi or bar scales available as order options, as are G or NPT threads instead of PT. This code is the low-pressure regulator type with a check valve fitted and no bracket. Because flow is published as curves, not a single rating, 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 the GFR600 as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator variant rather than the standard one. It is chosen where the downstream set pressure sits at the low end of the range; the exact adjustment window for this variant is not published in the sheet we work from, so we confirm it on request. Max inlet pressure is still 1.0 MPa (145 psi), temperature range is -5 to 70 C non-freezing, and the fitted square gauge reads in MPa.
