The AirTAC GFR600C25ALJF1WT AirTAC Filter Regulator NPT1 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.
GFR600C25ALJF1WT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air and holds downstream pressure at a set point. This configuration is the size 600 unit with a 1 in NPT port, a 5 um filter element (the W grade, finer than the 40 um standard), an automatic drain that ejects collected condensate without manual attention, the low-pressure regulator type, an embedded square gauge with MPa scale, no mounting bracket and no reverse/check valve. At size 600 the bowl is aluminium alloy, and the unit carries a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600, with PT, G and NPT thread options, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and scale choices, and bracket options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding filtered, regulated air to a spray-booth manifold, where water and fine particles must be stripped out before the air reaches atomising equipment, and the automatic drain keeps condensate moving during long shifts.
Supplying a packaging conveyor's pneumatic cylinders and diverters with clean air held at a steady set point, so indexing and clamping motions stay repeatable from the first carton to the last.
Conditioning the supply air ahead of a bank of directional control valves on a process skid, protecting spools and seals from water carryover while the low-pressure regulator type holds the manifold pressure where the valves were specified to run.
Start with the port step: this size 600 unit takes a 1 in connection, the largest in the GFR range, so choose it when your line is plumbed at 1 in or when the size 400 step down is too small for the job. Next, the drain: automatic (code A) suits points where nobody opens a drain valve regularly; manual needs an operator; differential-pressure is the default compromise. The 5 um element (W) is the right choice when downstream equipment is sensitive to finer particles; the 40 um standard element suits general supply. This unit is the low-pressure regulator type, so confirm the control band suits your circuit before ordering. The embedded square gauge reads in MPa; psi and bar scales are available as options. Thread here is NPT; PT is the catalogue standard and G is also offered. No bracket is fitted with the J code, so plan your own mounting.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and sizing against your required flow 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application and required flow and we will confirm the datasheet curves and check the sizing for you on request.
The A code in the model means the bowl drains itself: collected condensate is ejected automatically, so no one has to open a manual drain valve on a regular schedule. The W code selects the 5 um filter element instead of the 40 um standard, giving finer particulate removal downstream. Both choices are fixed in this configuration; the 40 um grade and a manual or differential-pressure drain are available on other GFR600 variants.
