The AirTAC GFR600C25AF2WTK 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 GFR600C25AF2WTK is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 configuration is fitted with a 1 in NPT port for high-flow supply lines, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The aluminium alloy bowl on this 600 size suits applications where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Installed at a large-distribution air drop feeding a production hall, the GFR600C25AF2WTK cleans the compressed air with its 5 um element and holds a steady regulated pressure for the whole downstream circuit, while the automatic drain keeps condensate out of the line without daily attention.
On a packaging or material-handling line where cylinders, grippers and air-driven conveyors run from one header, this 1 in NPT filter regulator protects and regulates the entire header, and the reverse/check valve holds downstream pressure if the compressor side is interrupted.
Fitted in the air-preparation cabinet of a press, machining centre or heavy pneumatic machine, the unit delivers filtered, regulated air to the machine's valve stack, with the psi square gauge giving operators a local setpoint readout and the aluminium bowl standing up to demanding shop-floor service.
Size and port set the capacity: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, chosen when line demand calls for the biggest port and flow path. The 5 um element (code W) is the right pick when downstream valves, cylinders or instruments need finer protection than the 40 um standard grade; note that finer filtration costs more pressure drop, so size the unit accordingly. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains remain available in the family if you prefer operator-controlled or demand-based draining. The square gauge here reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. NPT is ordered as a thread option - PT is the catalogue standard and G (BSPP) is also available. A mounting bracket is included with this configuration.
Because flow is published as curves and not a single rated number, we do not quote a rated flow figure. Send us your application details and we will confirm the datasheet and check the sizing against your demand 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 rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the datasheet curves and check that this size 600, 1 in NPT unit is correctly sized for your application before you order.
The A in the code sets an automatic drain: collected condensate is expelled by itself, which suits unattended or hard-to-reach installations (manual and differential-pressure drains are available on other codes). The W sets the 5 um filter element, one grade finer than the 40 um standard, for better protection of downstream valves, cylinders and instruments.
