The AirTAC GFR600C25ALF2WTK AirTAC 1 in NPT Filter Regulator 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 GFR600C25ALF2WTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit is built around a 1 in NPT port and carries the 5 um (code W) filter element, the automatic drain, the low-pressure regulator type, a metal bowl - aluminium alloy at size 600 - an embedded square gauge reading in psi, a reverse/check valve and the mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT to order, a choice of automatic, manual or differential-pressure drains, 40 um standard or 5 um elements, and MPa, psi or bar gauge scales. Flow for this series is published as curves rather than a single rated figure, and the exact regulation range of the low-pressure type is not in the published table, so ask us and we will confirm the datasheet 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.

Point-of-use conditioning on the main air drop feeding a machining center's clamps, fixtures and air-assisted circuits: water and fine particulate removed, pressure held steady at the low settings those circuits run at.
Conditioning the supply air at a palletizer or case-erector station on a packaging line, so the valves and cylinders downstream see clean, dry air and a regulated low pressure instead of raw header air.
Air preparation ahead of spray guns and coating pumps in a finishing booth, where the 5 um element protects the finish from fine particulate and the low-pressure type matches the modest regulated pressure coating equipment needs.
The decodable choices on this family are real ones. Step through sizes 200/300/400/600 and their ports (1/8 in to 1 in) to match the pipe and the duty of your line - the 600 size with a 1 in port is the top of the range. Choose the drain: automatic (as fitted here), manual, or the differential-pressure default. Choose the element: 40 um standard or 5 um (code W) for finer protection downstream. Choose the gauge scale - MPa, psi or bar - and the thread: PT is the standard, with G and NPT as order options; a bracket is included on this unit and the reverse/check valve is fitted. One honest note: AirTAC publishes flow for this series as curves, not a single rated number, and the regulation range of the low-pressure type is not published, so send us your application and we will confirm both 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 series as curves, not as a single rated figure, so we do not quote a number. Send us your application and we will confirm the datasheet flow curve and check the sizing against it on request.
The automatic drain (code A) discharges collected condensate on its own, which suits unattended or hard-to-reach installations. Manual and differential-pressure drains are the other catalogue choices on GFR units; the 5 um W element, the psi square gauge and the low-pressure regulator type on this model are separate decode options you can spec independently.
