The AirTAC GFR600-25G AirTAC Filter Regulator, G1 1 in, 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a G1 (1 in) port with G thread, a 5 um filter element for finer filtration than the standard 40 um grade, and a manual drain on the aluminium alloy bowl, so condensate is emptied by hand as part of a maintenance routine. A reverse/check valve is fitted, an external round gauge with a psi scale is included, and the unit is ordered without a mounting bracket. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). With the manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part in the GFR600 size, the largest of the G-series filter regulator range (sizes 200, 300, 400 and 600, with ports from 1/8 in up to 1 in). Across the range you can order automatic, manual or differential-pressure drains, a 40 um or 5 um element, embedded square or external round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

Point-of-use conditioning at a machining centre: the 5 um element and regulation in one body supply clean, controlled air to pneumatic clamps and tool-change circuits, with the manual drain emptied during scheduled shop-floor checks.
A packaging or bottling conveyor section where cylinders and diverters need filtered, regulated air at a set pressure; the manual drain suits lines that are blown down at shift end, and the psi gauge lets operators verify setpoint at a glance.
Finer 5 um filtration ahead of spray guns and air-assisted applicators in a paint booth, with the regulator holding a stable gun supply pressure; the check valve helps hold the downstream setting if upstream supply dips.
Start with the port and size step: the GFR600 carries a G1 (1 in) port, the top of the 200/300/400/600 range, so choose it when your line's flow demand sits above what the smaller bodies serve. Because flow is published as curves rather than one rated number, send us your application details and we will confirm sizing before you order. Next, pick the drain: this unit has a manual drain (code M), which also allows regulation down to 0.05 MPa (7-130 psi); automatic and differential-pressure drain versions regulate from 0.15 MPa (20-130 psi). Filtration is the 5 um element (code W) instead of the 40 um standard, for finer protection of downstream equipment. The gauge here is an external round type with a psi scale; the embedded square gauge is standard and MPa/psi/bar scales are available. Thread: PT is the standard, with G and NPT as order options - this unit is specified with G thread. This unit is ordered without a mounting bracket (code J); bracketed versions are available.
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 one number here. Send us your line pressure, downstream demand and duty, and we will confirm the relevant datasheet curve figures for the GFR600 at the G1 (1 in) port before you order.
The M code in GFR60025MJC2WGK specifies a manual drain: condensate is drained from the aluminium alloy bowl by hand on a maintenance schedule rather than automatically. One practical effect is the regulation range: manual-drain versions adjust from 0.05 to 0.9 MPa (7-130 psi), while automatic and differential-pressure drain versions start at 0.15 MPa (20-130 psi). Automatic and differential-pressure drains are available as alternative GFR configurations.
