The AirTAC AirTAC GFR600-25 Filter Regulator 1 in PT, 40 um 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 AirTAC GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit has a PT 1 in port, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and the standard 40 um filtration element. The 600-size bowl is aluminium alloy, and this configuration carries a round pressure gauge reading in psi plus a reverse/check valve that holds downstream pressure if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 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) filtration, gauge and scale choices, and an optional reverse/check valve. Flow figures for this family are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing 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 the take-off from a factory compressed-air main, it strips bulk water and pipe-scale from the supply and holds a steady regulated pressure for the downstream ring main, with the check valve protecting set equipment if the header is shut down.
Feeding the air cylinders and grippers on a bottling or carton-packing conveyor, it keeps line pressure stable so stopper and pusher strokes stay consistent shift after shift, while the 40 um element stops rust and pipe debris reaching the valves.
Mounted ahead of a pneumatic clamping or press circuit on a fabrication cell, it lets the setter dial in the clamping force via the psi gauge, and the reverse/check valve holds the clamp position during a momentary supply drop.
Size 600 with a 1 in PT port is the large-port step of the GFR range, chosen when the air demand at the regulator is high enough that smaller 200/300/400 bodies would be the bottleneck - size up against your flow requirement, not just your pipe thread. This code fixes the drain as differential-pressure (no manual or automatic drain suffix), the filtration grade at the 40 um standard (specify W for the 5 um element where finer particulate capture is needed), and the standard regulator type with a 0.15-0.9 MPa (20-130 psi) adjustment range. The C2 suffix means an external round gauge on a psi scale; square embedded gauges and MPa or bar scales are the other catalogue choices. The K suffix adds a reverse/check valve, and J means no mounting bracket is supplied. Thread is PT as standard; G and NPT are order options. Flow for this family is published as curves, not a single rating, so please 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 family as performance curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your operating pressure and required air demand and we will confirm the flow curve and sizing from the datasheet on request before you order.
The K suffix means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is interrupted. The drain on this code is the differential-pressure type (no A or M suffix): collected condensate is discharged automatically when the pressure differential across the bowl is sufficient, with no manual draining needed under normal duty.
