The AirTAC GFR600C25ALJF2WTK AirTAC Filter Regulator NPT 1 in 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 GFR600C25ALJF2WTK is an AirTAC GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit carries a 1 in NPT port and is built as the low-pressure regulator type (code L). It is fitted with the 5 um filter element (the finer of the two catalogue grades, code W), an automatic drain that expels collected condensate without operator attention, an embedded square gauge reading in psi, and a reverse (check) valve. The bowl on size 600 units is aluminium alloy, and no mounting bracket is included with this configuration. 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 is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G (BSPP) or NPT threads, with manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge and bracket options. Flow for this series is published as curves rather than a single rated figure, so we confirm the datasheet figures for your application on request.

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.

Supplies filtered, low-pressure regulated air to strapper heads and table cylinders, with the automatic drain clearing condensate across long production shifts.
Feeds 5 um filtered air to rinse-head and reject-gate cylinders on a bottling line, holding a steady low regulated pressure downstream of the compressor plant.
Regulates low-pressure air to the pneumatic edge-guiders and thread-up clamps on a textile stenter, with the psi gauge giving operators a local setpoint readout.
The real choices on this series: step the size and port to the air your line needs (sizes 200 through 600, ports 1/8 in to 1 in); pick the drain - automatic as fitted here, or manual or differential-pressure; choose the 40 um standard element or the finer 5 um W grade fitted here; select the gauge scale (MPa, psi or bar) and the embedded square gauge versus the optional external round gauge; order PT, G or NPT threads; and add or omit the mounting bracket. The L in this code marks the low-pressure regulator type, whose exact regulation range is not published in the catalogue.
Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing and the datasheet figures 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 GFR600 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, required regulated pressure and air demand, and we will confirm the sizing and the datasheet figures on request.
The A in the code fits the automatic drain, which expels collected condensate without operator attention - useful on lines that run unattended. The same GFR600 body can also be ordered with a manual or differential-pressure drain. Note that this unit is the low-pressure regulator type (code L), whose exact regulation range is not published, so we confirm it on request.
