The AirTAC GFR600C25C2WTK 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 GFR600C25C2WTK is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 unit is built around a 1-inch NPT port and carries a 5 um filter element (code W) in place of the 40 um standard, a differential-pressure drain (the family default), an external round pressure gauge reading in psi, and a fitted reverse/check valve (code K). The standard regulator adjusts across 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing. At this size the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures 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.

Clean, regulated air feeding pneumatic clamps and tool-change cylinders on a machining centre, where the 5 um element helps protect close-tolerance spools and the check valve holds the set pressure if the main supply dips.
Conditioning the air supply to spray booths and air-assisted applicators, where water and fine particulate must be stripped out and the atomising pressure held steady across a full shift.
Supplying the pick-and-place actuators and sealing cylinders on a high-cycle packaging machine, with the 1-inch port matching the main drop leg and the regulator keeping cylinder speeds consistent.
Size 600 with a 1-inch port is the largest GFR frame; choose it when your line size and air demand call for the biggest step, or step down to 300 or 400 where the port allows. This unit's W code selects the 5 um element for finer filtration than the 40 um standard, and the blank drain position means the differential-pressure drain - automatic (A) and manual (M) versions exist in the family if you prefer. The C2 code fits an external round gauge on a psi scale (square embedded gauges and MPa or bar scales are alternatives), and K adds a reverse/check valve to hold downstream settings if supply pressure drops. Thread here is NPT; PT is the standard and G is also an order option.
Flow for the GFR series is published as curves, not a single rated figure, so send us your working pressure and air demand 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 GFR-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this 1-inch, 5 um configuration before you order.
W selects the 5 um filter element instead of the 40 um standard; C2 fits an external round gauge with a psi scale (MPa and bar scales are also available); K adds a reverse/check valve. The blank drain position means the differential-pressure drain, with automatic and manual versions available elsewhere in the family.
