The AirTAC GFR600C25ALJF3TK 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 GFR600C25ALJF3TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a 1 in NPT port, 40 um standard filtration, an automatic drain and an aluminium alloy bowl. The regulator is the low-pressure type, the embedded square gauge is scaled in bar, a reverse/check valve is fitted, and no mounting bracket is included with this configuration. Maximum 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, and options include a 5 um filter grade (code W), manual or differential-pressure drains, MPa, psi or bar gauge scales, and PT, G or NPT threads. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

Feeding filtered, regulated air to grippers and gate actuators on a bottle-filling line, where the automatic drain keeps condensate out of the bowl without operator rounds.
Conditioning air ahead of a robotic weld cell's pneumatic tooling, with the fitted reverse/check valve helping hold the downstream circuit if upstream supply dips.
Regulating supply to diverter and stopper cylinders along a packaging conveyor, with the bar-scaled square gauge giving operators a local setpoint reference at the machine.
Every choice in this unit is decodable from the code. Size 600 with its 1 in NPT port is the largest step in the family and should be picked against the flow your line needs; because AirTAC publishes flow as curves rather than a single rated figure, send us your demand and we will confirm the correct size from the datasheet before you order. Drain type matters: automatic (this unit) removes condensate without operator intervention, while manual and differential-pressure drains suit attended or load-following installations. Filter grade is 40 um standard or 5 um with code W, the gauge can be ordered with MPa, psi or bar scales (bar here), and threads are available in PT or G as well as NPT. This is the low-pressure regulator type; its exact adjustment range is not published, so confirm your setpoint with us if it is critical to the application.
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 GFR600 series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your line demand and operating pressure and we will confirm the correct size and flow from the datasheet before you order.
The L code marks the low-pressure regulator variant, intended where the controlled pressure sits below what the standard type covers. AirTAC does not publish the exact adjustment range for this variant, so tell us your setpoint and we will verify it against the datasheet before you order.
