The AirTAC GFR600C25LJC2TK 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 GFR600C25LJC2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built for 1 in NPT ports and is the low-pressure (L) regulation type, intended for circuits that hold a reduced working pressure below the standard range. It carries the standard 40 um filter element, a differential-pressure drain on the bowl, a round external gauge reading in psi, and a built-in check (reverse) valve that allows downstream back-flow when the inlet is depressurised. The size 600 bowl is aluminium alloy, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across the range include 5 um filtration (code W), automatic or manual drains, an embedded square gauge or an external round gauge in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow for this unit is published as a curve rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Feeding the filling and capping section of a bottling line from a 1 in NPT main, holding a reduced working pressure for the section's actuators while the 40 um element strips water and pipe scale from the supply.
Supplying stoppers, pushers and diverter cylinders along a packaging conveyor, where the low-pressure regulation type holds a gentle set pressure for smooth gate action and the check valve keeps cylinders from venting on inlet loss.
Actuating big diaphragm or quarter-turn pneumatic valves on a process skid, with the 1 in NPT port matching the actuator supply line and the round psi gauge giving the operator a direct set-pressure readout.
Pick the size by port and duty: this is size 600, the largest step in the GFR range, with a 1 in NPT port for high-capacity mains. Drain choice matters: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) drains are order options. Filtration is the standard 40 um element; specify W for the 5 um grade where finer particulate removal is needed. The gauge in this configuration is an external round type scaled in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as catalogue options to order - this unit is ordered with NPT. It is ordered without a mounting bracket (J) and with a check (reverse) valve fitted (K).
Flow is published as curves, not a single rating, so ask us to confirm sizing against your line pressure, set pressure and air demand 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 a curve, not a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and expected air demand and we will confirm sizing from the datasheet on request.
L marks the low-pressure regulation type. It is chosen for circuits that hold a reduced working pressure below the standard regulator range; the exact range for this type is not published in the catalogue, so confirm it with us before ordering.
