The AirTAC GFR600C25LJF2TK 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 GFR600C25LJF2TK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single body. This size 600 unit is built for a 1 in NPT port, filters to the standard 40 um grade, and drains collected condensate by differential pressure. The regulator is the low-pressure type, a square pressure gauge reading in psi is fitted, and a reverse/check valve is included. At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket.
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, and can be ordered with automatic or manual drains, a finer 5 um element (code W), G or NPT threads, and with or without a gauge or bracket. Maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing. Flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Conditioning the main air drop feeding the actuator network on a beverage bottling line: the 1 in NPT connection suits a high-consumption header, while the regulator holds the downstream set point for the line's valves and grippers.
Filtering and regulating supply air ahead of spray guns and air-driven agitators in a paint booth. The 40 um element catches water and pipe scale, and the low-pressure type regulator suits applications set below the standard pressure range.
Supplying the stopper, pusher and clamp cylinders on a packaging conveyor, with the fitted reverse/check valve protecting the downstream circuit and the differential-pressure drain clearing condensate as the unit works.
The real choices in this family are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread, and the bracket. Sizes 200 to 600 step from 1/8 in up to 1 in ports as your air demand grows; this unit is already at the top of the range on a 1 in NPT connection. Drains come as differential-pressure (this unit), automatic (code A) or manual (code M). The standard element is 40 um, with a 5 um element (W) where finer filtration is needed. Gauges are square (embedded) or round (external) with MPa, psi or bar scales; this one carries a square psi gauge. Thread is PT as standard, with G and NPT as order options - this unit is NPT. The low-pressure regulator variant and its adjustment range can be confirmed on request. Because flow is published as curves rather than 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 line pressure, set pressure and air demand, and we will confirm the flow and sizing from the datasheet on request.
The L marks the low-pressure regulator variant, intended for applications set below the standard range. AirTAC does not publish a separate adjustment figure for this variant, so we confirm the exact range from the datasheet on request. Everything else decodes normally: 1 in NPT port, 40 um element, differential-pressure drain, square psi gauge and a fitted reverse/check valve.
