The AirTAC GFR600-25T AirTAC Filter Regulator, NPT 1 in 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 GFR600-25T-A-F3-W-K is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is built around a 1 in NPT port, with the 5 um filter element (code W) in place of the standard 40 um, an automatic drain that clears collected condensate without manual attention, and an aluminium alloy bowl on the 600 frame. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), the embedded square gauge is supplied with a bar scale, a reverse (check) valve is fitted, and the mounting bracket is included. Maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, PT/G/NPT thread options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filter elements, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Filtered and regulated air at the 1 in main feeding paint booths, where the 5 um element helps keep water and particulate out of finishing air and the automatic drain handles condensate without daily attention.
Steady regulated pressure to cylinders and actuators on a high-cycle packaging conveyor, with the fitted check valve holding downstream pressure if the supply side dips.
Point-of-use preparation for clamp and pneumatic tool circuits on a machining center, with the bar-scale square gauge giving operators a local pressure reference at the machine.
Size and port set the air capacity: step up through the 200, 300, 400 and 600 frames as your flow demand and piping grow - this unit is the 600 frame on a 1 in NPT connection. Choose the drain to suit access: automatic (fitted here) suits enclosed or infrequently visited installations, manual suits attended points, and the differential-pressure default drains only under a pressure differential. Filter grade is 40 um standard or 5 um (W) where finer protection is needed - this unit carries the 5 um element. Gauge scale is selectable in MPa, psi or bar (bar fitted here), thread is PT as standard with G and NPT as order options (NPT fitted here), and the bracket is included. Flow is published as curves, not a single rating, so 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 rather than a single rated figure, so we do not quote a number here. Ask us and we will confirm the flow curve and the datasheet figures for this size 600, 1 in NPT unit against your application before you order.
The W code fits a 5 um element in place of the standard 40 um, giving finer removal of particulate and water carryover for sensitive downstream equipment such as valves, cylinders and finishing tools. If your application does not call for fine filtration, the standard 40 um element is also available across the GFR family.
