The AirTAC GFR600C25AF2T AirTAC Filter Regulator 1 in NPT 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 See datasheet 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 GFR600C25AF2T is a filter regulator: a water-and-particulate filter and a pressure regulator combined in one body, so a single 1 in NPT connection both cleans the compressed air and holds downstream pressure steady. This unit is the size 600 frame with an automatic drain that bleeds collected condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, and an embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
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, and options include manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, an external round gauge, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket - included on this unit. Flow for this family is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers for 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 0.15 - 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 drop to a paint booth, the unit removes water and pipe scale from the shop air and holds a steady regulated pressure to the spray guns, supporting consistent finish quality on vehicle panels.
On a beverage bottling conveyor, the filter regulator conditions and regulates the air feeding pick-and-place grippers and stopper cylinders, keeping bottle handling repeatable through the shift.
Mounted at the wall drop in a woodworking shop, it dries and filters the compressor supply and sets a fixed working pressure for nailers, staplers and orbital sanders at each bench.
The real choices in this family are decodable from the code. Step up or down through sizes 200, 300, 400 and 600 - and the matching port from 1/8 in to 1 in - against the air demand of the line; this unit is size 600 with a 1 in NPT port. Choose the drain: automatic (this unit) for unattended condensate removal, manual for periodic draining, or the differential-pressure default. Filter grade is 40 um standard or 5 um with code W when finer filtration is needed. The gauge can be the embedded square type or an external round gauge, scaled in MPa, psi or bar - this unit reads psi. Thread is PT as standard with G (BSPP) and NPT as order options; a bracket is included here. Flow for GFR units is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the flow from the datasheet for this size 600, 1 in NPT unit on request.
This unit carries code A, the automatic drain, which discharges collected condensate from the bowl by itself. The manual-drain version (code M) is emptied by hand, and the differential-pressure drain (blank) is the catalogue default. The manual-drain variant also widens the regulating range to 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for this automatic-drain unit.
