The AirTAC GFR600C25AJF1WT 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 GFR600C25AJF1WT is an AirTAC GFR600 filter regulator: a 5 um filter element and a pressure regulator combined in one body, sized for a 1 in NPT port. This configuration carries an automatic drain, an aluminium alloy bowl, an embedded square pressure gauge scaled in MPa, and no mounting bracket (code J). With the standard regulator, outlet pressure is adjusted across 0.15-0.9 MPa (20-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, a choice of 40 um standard or 5 um (code W) filtration, differential-pressure, automatic or manual drains, and PT, G or NPT threads. Flow for this model is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Installed downstream of the receivers on a food and beverage bottling plant, it strips water and particles from the 1 in main and holds a steady regulated supply to the factory air ring.
Feeding the solenoid manifold bank of a palletizing cell, the unit conditions the main air drop and keeps actuator supply pressure within the set band.
On a truck dealership service-shop ring main, it supplies lift bays and impact-wrench drops with filtered, regulated air at the 1 in trunk connection.
Size and port set the capacity step: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so match it against the air demand of your line. Drain choice matters: automatic (as fitted here, code A) ejects condensate without operator attention, manual (M) needs someone to open it, and the differential-pressure default drains on a pressure drop. Filtration is 5 um on this model (code W) instead of the 40 um standard element. The square gauge is scaled in MPa; psi and bar scales are available, and an external round gauge is optional. Thread is NPT here; PT is the standard and G is also a catalogue option. No mounting bracket is included (code J). Flow is published as curves, not a single rating, so 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 this series as curves rather than a single rated figure, so we do not quote a number. Send us your line demand and we will confirm the datasheet flow curve and sizing for your application on request.
A is the automatic drain: the bowl ejects collected condensate on its own, with no operator action. The alternatives in this series are manual drain (code M) and the differential-pressure default. The drain type also sets the regulation range: with an automatic drain, outlet pressure is adjustable across 0.15-0.9 MPa (20-130 psi).
