The AirTAC GFR600C25LJC2T AirTAC Filter Regulator NPT1 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 GFR600C25LJC2T is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port, the 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential builds, so no manual draining routine is needed. It is the low-pressure (L) regulator type, supplied with a round gauge reading in psi, ordered without a mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 covering ports from 1/8 in to 1 in, with a choice of differential-pressure, automatic or manual drain, an optional 5 um (code W) element, square or round gauges in MPa, psi or bar scales, PT (standard), G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request.

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 filtered, low-pressure regulated air to clamping and holding cylinders on a metal stamping line, where the 1 in port serves a high-demand header and the differential drain keeps condensate out of the clamp valves.
Conditions the air feeding blow-off nozzles and air knives on a carton-sealing conveyor, removing water and 40 um particulate before it reaches the nozzles while holding a stable low regulated pressure.
Supplies filtered, regulated air to the ejector and core-pull pneumatics on a plastics injection molding machine, with the psi gauge giving the setter a direct pressure readout at the machine.
Start with the port step: size 600 carries a 1 in connection, the largest in the GFR range, so step down to 400/300/200 if your line runs smaller ports and lower air demand. Choose the drain to match maintenance access: differential-pressure (this unit) drains itself, automatic (code A) drains on cycle, and manual (code M) needs an operator. Filter grade is 40 um standard here; specify W for 5 um where downstream equipment needs finer filtration. This unit carries the L low-pressure regulator type - its exact regulation range is not published, so confirm it against your set pressure before ordering. The round psi gauge is fitted; square gauges and MPa/bar scales are alternatives. Thread is NPT here; PT is the standard thread and G is the other order option. Brackets are optional and this unit was ordered without one. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow and we will confirm the correct sizing from the datasheet on request.
L marks the low-pressure regulator type. This unit regulates at reduced set pressures rather than the standard range, and the exact range for the low-pressure type is not published in the catalogue - confirm your set pressure with us before ordering. The rest of the code reads: 600 size with 1 in NPT port, C round psi gauge, J no bracket, T NPT thread, with the 40 um element and differential-pressure drain as defaults.
