The AirTAC GFR600C25AJNTK 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 GFR600C25AJNTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, standard 40 um filtration, a standard-type regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No pressure gauge is fitted and no mounting bracket is included. At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with manual or automatic drains, a 5 um filter element (code W), gauge options, PT or G threads, and bracket choices. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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 at a main air drop in a manufacturing plant, it filters water and scale out of the compressed-air header and holds a steady regulated supply to the downstream distribution manifold.
Mounted on the air preparation drop feeding pneumatic cylinders and actuators on a packaging or palletising conveyor, it keeps moisture and debris out of the valves while holding the set working pressure.
Fitted on the utility-air feed to a laboratory or test-bench setup, it delivers clean, regulated air to bench equipment, with the automatic drain handling condensate from intermittent demand.
Start with the port size: this unit is the 1 in NPT version of the size-600 body, the largest step in the GFR range, so choose it when your line's required flow sits at the top of the range and confirm the match against the published flow curves before ordering. Drain choice matters: this unit has an automatic drain, while manual-drain versions widen the regulation range down to 0.05 MPa and suit attended installations. Filtration is the standard 40 um element; specify the W code for 5 um where finer particulate removal is needed. No gauge is fitted on this code, but gauge options with different scales are available in the family. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an order option. No mounting bracket is included on this code, and bracket options exist across the family. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet on request.
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 number, so we do not quote a figure here. Tell us your application and required flow and we will confirm sizing against the datasheet on request.
The A in the code means an automatic drain, which expels collected condensate without manual attention. Manual-drain GFR versions extend the regulation range down to 0.05 MPa (7 psi), while this automatic-drain unit adjusts from 0.15 to 0.9 MPa (20-130 psi). Choose the drain type that matches how the installation is attended.
