The AirTAC AirTAC GFR600-25G Filter Regulator, G1 (1 in) 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 AirTAC GFR600-25G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a G1 (1 in) G-thread port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. The standard regulator covers 0.15-0.9 MPa (20-130 psi), and this configuration is fitted with a round gauge reading in psi. The aluminium alloy bowl suits the larger 600 frame, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR600 series, the largest of the four G-series sizes (200/300/400/600). Options across the series include 5 um filtration (code W), automatic or manual drains, square embedded or round external gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm sizing and 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 at the take-off from a large compressor ring main, the GFR600-25G cleans water and scale from the 1 in supply line and holds a set header pressure for the whole cell.
Feeding the air cylinders and clamps on a palletising or packaging conveyor line, the unit keeps grit and condensate out of the actuators while holding a stable working pressure.
Mounted ahead of a machine's valve manifold and FRL distribution block, the filter regulator protects directional valves and cylinders from contamination and pressure drift.
Size 600 with a G1 (1 in) port is the top of the G-series range; step down to 200/300/400 if your line's flow demand is modest, and match the port to your existing pipework (G/BSPP here, with PT and NPT available to order). The 40 um element is the standard choice for general plant air; choose the 5 um W option where downstream valves and instruments need finer protection. The differential-pressure drain suits steady-running lines; pick an automatic drain for unattended duty or a manual drain where you want positive control. The round psi gauge on this unit matches US-style pressure reading; MPa and bar scales are alternatives. A mounting bracket is included. Because flow is published as curves rather than 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and demand, and we will confirm the sizing against the datasheet curves on request before you order.
This GFR600-25G has no drain code, which means the differential-pressure drain: condensate collected in the aluminium bowl is discharged automatically when the pressure differential across the bowl is sufficient. If you prefer an always-automatic float drain or fully manual draining, those are available as coded options.
