The AirTAC GFR600C25LJF2T 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 GFR600C25LJF2T is a size 600 filter regulator that removes water and particulate from compressed air and reduces pressure to the downstream circuit in a single body. This configuration is built around a 1 in NPT port for high-flow plant air drops, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. The regulator is the low-pressure type, and an embedded square gauge with a psi scale is fitted so the set pressure is visible at the unit. The bowl on this size 600 unit is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and no reverse/check valve or mounting bracket is fitted.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the family you can order manual or automatic drains instead of the differential-pressure drain, a 5 um element (code W), gauge scales in MPa, psi or bar, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket where the family supports one. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the 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.

Mounted at the air drop feeding a carton-wrapper section, this unit strips water and debris from the shop air and lets the line set a reduced, stable supply pressure for the wrapper's low-pressure actuators, with the psi gauge showing the setting at a glance.
Installed ahead of the stopper and gate cylinders on a conveyor transfer, it cleans the incoming air and holds the reduced pressure those cylinders were set up for, while the differential-pressure drain keeps condensate out of the valve circuit.
Placed on the supply to a CNC machine's pneumatic fixture-clamp circuit, it filters machining-air contamination down to 40 um and regulates the clamp pressure to the value the fixture was designed around, read directly off the fitted psi gauge.
Start with the port step: this unit is size 600 with a 1 in NPT port, the largest step in the GFR family - if your line sits below that, the 200/300/400 sizes with smaller ports may suit better, and the right choice depends on the flow your circuit needs. Because flow for this series is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order. Other decodable choices: the drain here is differential-pressure (the default); automatic (code A) and manual (code M) drains are available. The 40 um element is standard - specify code W if you need 5 um filtration. The fitted square gauge reads in psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread on this series, with G (BSPP) and NPT as order options - this unit is ordered in NPT. The regulator is the low-pressure type; the standard type is the alternative. This unit ships without a mounting bracket (code J), and no reverse/check valve is fitted.
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 number, so we do not quote a flow figure for this unit. Send us your line pressure and the flow your circuit needs and we will confirm the sizing against the datasheet before you order.
This unit is ordered with the differential-pressure drain (the default): collected condensate is discharged automatically when the pressure differential across the bowl is high enough, with no operator action. If you prefer, the GFR family can be ordered with an automatic drain (code A) or a manual drain (code M) instead.
