The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT Auto Drain 5 um 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 AirTAC GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the size 600 unit with a 1 inch PT port, an automatic drain that ejects collected condensate without manual attention, a fine 5 um filter element (the W grade, against the 40 um standard), and an aluminium alloy bowl, which is the bowl material used at size 600. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A square pressure gauge graduated in psi is fitted as standard.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with manual, automatic or differential-pressure drains, 40 um or 5 um elements, PC or aluminium bowls depending on size, square or external round gauges with MPa, psi or bar scales, a low-pressure regulator type, a reverse/check valve option, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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.

Dropped from a large-diameter main at the packaging hall, this 1 in filter regulator conditions and sets the supply pressure feeding a whole bank of case packers, sealers and labelers, with the automatic drain handling condensate on a header that is not checked every shift.
Installed ahead of the machine's air preparation inlet on a CNC machining center, it removes water and fine particulate that would otherwise score pneumatic tool-change cylinders, and holds a stable regulated pressure for clamping and tool-cleaning circuits.
Mounted at the feed end of a bottling or carton conveyor line, it filters the plant air to 5 um before it reaches diverter gates, stoppers and pusher cylinders, and regulates it to the pressure the gate actuators were set up for.
Start with the port and size step: size 600 with a 1 in PT port sits at the top of the GFR range and is the choice when the line demand calls for the largest ports; step down to 300/400 or 200 with smaller ports when flow demand is lower. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. This unit carries the 5 um (W) element - choose it where downstream valves, cylinders or instruments need finer filtration than the 40 um standard; the automatic drain suits points that are not visited daily, while manual and differential-pressure drains remain available in the family. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
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 the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GFR60025AF2W sets the automatic drain, which ejects collected condensate on its own - useful where the unit is mounted out of easy reach. The W sets the 5 um filter element instead of the 40 um standard, for finer protection of downstream valves, cylinders and instruments. Both are catalogue options; manual drain and 40 um versions of the same size are available.
