The AirTAC GFR60025C2K AirTAC Filter Regulator 1 in PT Port 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 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 GFR60025C2K is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size-600 unit has a 1 in PT port, a differential-pressure drain, a 40 um filter element and an aluminium alloy bowl. It is supplied with a round psi gauge, a reverse (check) valve and a mounting bracket, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional 5 um filtration (code W), automatic or manual drains, G (BSPP) or NPT thread options, and a choice of gauge scales. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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.

Installed on the 1 in main air line of a bottling hall, it strips water and scale from the compressor supply and holds a steady pressure to clamp and gate cylinders so bottle handling stays repeatable.
Feeding diverter gates and stop cylinders along a distribution conveyor, the 40 um element protects seals from particulate while the regulator keeps actuation pressure constant through the shift.
On a water-treatment or chemical dosing skid, it conditions the air feeding pneumatic positioners and control valves, with the check valve helping hold downstream pressure if the supply dips.
Size and port set the air capacity: this 600 size with a 1 in PT port is the largest standard step when your main line needs the biggest connection in the range. Choose the drain to suit maintenance: differential-pressure (this unit), automatic (code A) for unattended condensate dropping, or manual (code M). Filter grade is 40 um standard; specify W for 5 um where finer protection is needed. The embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit carries a round psi gauge. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is included. Flow is published as curves, not a single rated figure, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so there is no one number we can quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
K means a reverse (check) valve is fitted, which helps hold the regulated downstream pressure if the upstream supply drops. Other decodable choices on this unit are the differential-pressure drain, the 40 um element (5 um with code W) and the round psi gauge.
