The AirTAC GFR600C25LJC3TK 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 GFR600C25LJC3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a drain bowl but no lubricator. This 600-size unit connects at 1 in NPT and carries the 40 um standard filter element with a differential-pressure drain. It is the low-pressure (L) type, intended for circuits that hold a lower regulated set-point than a standard unit; the exact adjustment range for this type is not published, and we confirm it from the datasheet on request. A round gauge with a bar scale is fitted, a reverse/check valve is included, the 600-size bowl is aluminium alloy, and no mounting bracket is supplied with this code. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
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, a choice of differential-pressure, automatic or manual drains, a 5 um (W) element option, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm sizing and the datasheet figures before you order.

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.

Conditioning the main air feed to a stamping or forming press: the 40 um element strips water and particulate before the regulator holds the circuit set-point, all in one 1 in NPT body.
Feeding atomizing air on a paint or coating line where the low-pressure type holds a gentler regulated set-point than a standard unit, with the bar-scale gauge for local setting at the booth.
Supplying filtered, regulated air to carton-former and wrapper actuator banks on a packaging line, with the differential-pressure drain handling condensate as the line runs.
Choose the size by port and required flow: the 200/300/400/600 range steps up from 1/8 in to 1 in, and this unit already sits at the top of the range with its 1 in NPT connection. The regulator type is a real choice: this is the low-pressure (L) type for circuits holding lower set-points, while the standard type is the alternative; the low-pressure adjustment range is not published, so we confirm it on request. Drain type matters too: this code uses the differential-pressure drain (standard), with automatic (A) for unattended draining or manual (M) as the other options. Filter grade is 40 um here; specify W for the 5 um element where finer particulate matters. The fitted gauge is round with a bar scale; an embedded square gauge and MPa or psi scales are the alternatives. Thread can be ordered as PT (the standard), G (BSPP) or NPT, and a mounting bracket is optional - this code is supplied without one. 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application - port size, downstream demand and set-point - and we will confirm sizing and the relevant datasheet figures on request.
L marks the low-pressure type of regulator. It is intended for circuits that hold a lower regulated set-point than the standard type; the exact adjustment range for this type is not published, so we confirm it from the datasheet on request. Standard-type GFR units are the alternative for conventional set-points.
