The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, 5 um, psi Gauge 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 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 size-600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration carries a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and a fitted reverse/check valve that holds downstream pressure if the upstream supply drops. The port is PT1 (1 in, PT thread standard). Outlet pressure is set with the fitted external round gauge, which reads in psi; the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. At size 600 the bowl is aluminium alloy, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge and scale options, and an optional low-pressure regulator type. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and check the curve against 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-diameter air drop feeding a production hall, the unit filters water and particulate from the main supply and holds a steady regulated pressure for the tools and actuators served by that drop, while the check valve keeps downstream circuits pressurised during compressor unload or brief supply dips.
On a packaging line with case erectors, tape heads and pneumatic diverters, the 5 um element protects cylinders and valve manifolds from finer contamination, the regulator holds consistent working pressure so seal and clamp actions stay repeatable, and the differential-pressure drain keeps condensate moving out without daily manual attention.
Feeding pneumatic test benches, air-bearing fixtures or lab process panels, the unit cleans the shop supply down to 5 um and trims it to the pressure the bench needs, the psi gauge gives operators a direct local readout, and the check valve prevents backflow from the bench into the shop ring main.
Size 600 with a PT1 (1 in) port is the largest step in the GFR range, so size the unit against the air demand of the circuit rather than the pipe size alone - a unit that is too small for the flow will drop pressure across the element. Choose the drain to match access: this code uses the differential-pressure drain, which needs no daily attention but relies on flow to purge; a manual drain suits attended installations and an automatic drain suits unattended ones. The 5 um W element here is the finer of the two published grades (40 um standard) - pick 5 um where downstream equipment is sensitive to finer particulate. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. The fitted reverse/check valve holds downstream pressure through supply dips. Thread is PT as standard; G and NPT are order options. No bracket is included with this code, so plan the mounting. 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 number, so we do not quote a l/min, m3/h or SCFM figure. Ask us and we will confirm the datasheet and read the flow curve for your inlet pressure and set pressure so you can size the unit correctly before ordering.
The W in the code GFR60025JC2WK selects the finer 5 um filter element instead of the 40 um standard, and the K selects a fitted reverse/check valve that holds downstream pressure if the upstream supply drops. The drain is the differential-pressure type (the default): it purges collected condensate automatically when the pressure differential across the element is high enough, with no manual draining required.
