The AirTAC AirTAC GFR600-25 Low-Pressure Filter Regulator 1 in PT is a genuine G-series filter regulator: water separation, 5 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 GFR600-25ALJC2WK is an AirTAC GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size-600 unit with a 1 in PT port, the 5 um filter element (code W), an automatic drain, and the low-pressure regulator type. At size 600 the bowl is aluminium alloy, the automatic drain handles condensate without daily manual bleeding, and the fitted round gauge reads in psi. A reverse/check valve is fitted, and this build comes without a mounting bracket.
This is a genuine AirTAC part. The GFR line runs from size 200 to 600 with ports from 1/8 to 1 in, with differential-pressure, automatic or manual drains, 40 um standard or 5 um filtration, embedded square gauges as standard with an external round gauge optional in MPa, psi or bar scales, and PT, G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Conditions the air feeding a press actuator circuit: water and chips are dropped out through the 5 um element while the low-pressure regulator holds the actuator circuit at its set pressure, and the auto drain keeps condensate moving without an operator bleeding the bowl each shift.
Sits at the drop point where a bottling or cartoning line branches off the main header, filtering and regulating the air that runs gripper cylinders and stopper gates, with the psi gauge giving operators a local reading at the machine.
Prepares the air feeding spray guns in a paint booth: the 5 um grade catches fine particulate that would spoil a finish, the regulator holds gun supply pressure steady, and the reverse/check valve backs up the line against backflow.
The real, decodable choices on this family: step size and port against the flow your line needs (200/300/400/600, ports 1/8 to 1 in); drain type - differential-pressure as the default, automatic where condensate should be handled without manual bleeding, or manual; and filter grade, 40 um standard or 5 um where finer particulate matters. Gauge style and scale (embedded square standard, external round optional, MPa/psi/bar), thread (PT standard, G or NPT to order) and the bracket option are all carried in the code, as is the reverse/check valve. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing from the datasheet before you order.
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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure and the demand of the equipment downstream and we will confirm the sizing from the datasheet on request before you order.
It marks the low-pressure regulator type. This build regulates at the low end of the range rather than the standard type, and the exact adjustment range for the low-pressure build is not published in the catalogue, so we confirm it on request. The unit still carries a 1.0 MPa (145 psi) max inlet pressure and a -5 to 70 C working range.
