The AirTAC GFR600C25LJF2K AirTAC Filter Regulator PT1 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 GFR600C25LJF2K is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size-600 unit is built for 1 in PT ports, carries the standard 40 um filter element, and drains condensate through the differential-pressure drain, the default drain type for the series. It is the low-pressure (L) regulator type, fitted with an embedded square gauge scaled in psi and a reverse/check valve, and it comes without a mounting bracket. The bowl on the 600 frame is aluminium alloy, the maximum inlet pressure is 1.0 MPa (145 psi), and the working 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 up to 1 in, and options across the range include a 5 um filter element (code W), automatic or manual drains, alternative gauge scales in MPa or bar, an external round gauge, G (BSPP) or NPT threads, and a mounting bracket. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the 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.

Mounted at the supply drop feeding a paint booth, the unit strips water and particulate from the shop air line and holds a set downstream pressure for the booth's spray equipment. The low-pressure regulator type suits circuits regulated well below full header pressure, and the reverse/check valve is already fitted.
Installed on the 1 in main feeding a machining cell's pneumatic valves and clamps, the filter section removes water and particles ahead of the regulators on each machine, while the integral regulator sets the cell's working pressure from one point. The square psi gauge gives a direct readout for US-standard circuits.
Placed where the main air header branches to a packaging line's conveyor cylinders and diverters, the unit filters incoming air and regulates the branch to the pressure the actuators need. The differential-pressure drain handles condensate in the 1 in line, and the aluminium alloy bowl suits the larger 600 frame.
Choose the size and port step against the air demand of the line: this configuration is size 600 with a 1 in PT port, the largest step in the GFR range. The drain here is the differential-pressure type (the default), with automatic and manual drains available as order options. The filter element is the standard 40 um grade; specify W for the 5 um element when finer filtration is needed. The gauge is the embedded square type scaled in psi, with MPa or bar scales and an external round gauge as options. Thread is PT as standard, with G (BSPP) and NPT available to order, and this unit is supplied without a mounting bracket. Flow for the series is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from the datasheet 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.
Flow for the GFR series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet figures for this exact model before you order.
The L in the code marks the low-pressure regulator type, intended for circuits regulated well below full line pressure. The exact regulation range for this type is not published in our sheet, so ask us and we will confirm it from the AirTAC datasheet. Everything else on this unit is standard: 40 um filtration, differential-pressure drain, and a square gauge scaled in psi.
