The AirTAC GFR60025ANTK 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 PT1" ports, a automatic 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 GFR60025ANTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single 600-size body with a 1 in NPT port. This configuration carries a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, a built-in reverse/check valve, and no gauge fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the aluminium alloy bowl suits this largest 600 frame. Maximum working (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 is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, gauge options and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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 large distribution drop feeding a production hall, it strips water and pipe-scale from the main supply and holds a steady regulated pressure to the whole downstream circuit, with the automatic drain handling condensate without daily attention.
On a beverage bottling line, it feeds the conveyor stoppers, pushers and lift cylinders with clean, regulated air, protecting the actuators from water carryover while the check valve holds downstream pressure if the supply dips.
On a water-treatment or process skid, it conditions and regulates the air feeding pneumatic ball and butterfly valve actuators, keeping their stroke pressure stable and the supply free of condensate and particulate.
The 600 size with a 1 in NPT port is the largest step in the GFR range; size up from 400 when your line's flow demand sits above what the smaller ports serve, and check the published flow curve against your consumption rather than guessing. Drain choice matters here: the automatic drain on this model suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the other catalogue options. The 40 um element is the standard grade; specify the W code for the 5 um element where finer particulate removal is needed. No gauge is fitted on this code, so plan your downstream pressure monitoring accordingly, and note the built-in reverse/check valve is already included. Thread is NPT on this model; PT is the standard thread and G is the other order option. A mounting bracket is included. Because flow is published as curves and not a single rating, 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. The reflux valve permits reverse flow 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 figure, so we do not quote a number. Tell us your port size, upstream pressure and required downstream flow, and we will confirm the sizing from the datasheet on request before you order.
The N code in GFR60025ANTK means no gauge is fitted; gauge options are available in the GFR range if you want a fitted indication. The A code means an automatic drain, which expels collected condensate from the aluminium bowl by itself, unlike the manual or differential-pressure drain options.
