The AirTAC GFR600C25LJF1T AirTAC Low-Pressure 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 GFR600C25LJF1T is an AirTAC GFR-series filter regulator: water and particulate removal plus pressure regulation combined in a single body. This 600-size unit carries a 1 in NPT port, the standard 40 um filter element, and the differential-pressure drain, which is the default drain option for this family. The regulator is the low-pressure type, an embedded square gauge scaled in MPa is fitted, and the 600-size bowl is aluminium alloy. No mounting bracket is included on this code.
This is a genuine AirTAC part. The GFR family spans 200 to 600 sizes with ports from 1/8 in to 1 in, and catalogue options include a 5 um element (code W), automatic or manual drains, G (BSPP) or NPT threads in place of the standard PT, psi or bar gauge scales, an external round gauge in place of the embedded square one, and a mounting bracket. 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.

Point-of-use conditioning ahead of a directional-valve manifold on an automated machine line: the element strips water and pipe debris while the low-pressure regulator holds a reduced setting to the valves.
Feeding cylinders and actuators on a packaging or bottling line that runs at a reduced pressure, with the 1 in port suiting a take-off from a main plant air header.
A filtered, regulated drop at a maintenance workshop bench: clean, moisture-reduced air at a set low pressure for impact wrenches, ratchets and blow guns.
Size and port step up together with flow demand: 200 through 600, ports 1/8 in to 1 in. This unit is the top of the range at 1 in NPT. Drain options are differential-pressure (default, fitted here), automatic (A) and manual (M). Filter grade is 40 um standard (fitted) or 5 um with code W. The gauge on this code is the embedded square type scaled in MPa; psi or bar scales and an external round gauge are order options. Thread is NPT here; PT is the standard and G (BSPP) is the alternative catalogue option. No bracket is included, but one is available. The L code selects the low-pressure regulator variant; its exact adjustment range is not published in our data, so confirm it with us before ordering. Flow is published as curves, not a single rating, so ask us to check the curve 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and full datasheet figures for this model on request.
The L code selects the low-pressure regulator variant rather than the standard one. The exact adjustment range for the low-pressure type is not published in our data, so we confirm it on request before you order. The rest of the code decodes as standard: 40 um element, differential-pressure drain, embedded square gauge scaled in MPa, and a 1 in NPT port.
