The AirTAC GFR60025AC2WTK AirTAC Filter Regulator NPT1 5 um 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 GFR60025AC2WTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 configuration has a 1 in NPT port, a 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round external gauge with a psi scale is fitted so the set pressure can be read directly. The bowl on this size is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, a low-pressure regulator type, a reverse/check valve, and PT, G or NPT threads. Because flow for this series is published as curves rather than a single rated figure, we confirm the datasheet and flow 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.

At a 1 in NPT port this unit sits on the main air drop feeding a machining cell, filtering water and swarf-carrying particulate out of the supply and holding a steady regulated pressure to the clamps and pneumatic tooling.
On a packaging or case-erecting line, the filter regulator conditions the air feeding cylinder-driven diverters and pushers: the 5 um element protects valve spools, the automatic drain keeps condensate off the line between shifts, and the check valve holds the set pressure if the upstream supply dips.
Where quarter-turn valves are actuated pneumatically, this unit filters and regulates the actuator supply at the panel: the psi gauge gives operators a readable setpoint, the automatic drain suits a panel that is not visited daily, and the reverse/check valve prevents backflow out of the branch.
Start with the port and size: this unit steps up to the GFR600 with a 1 in NPT port, the largest in the range, so match it against the pipe diameter and the air demand of the circuit it feeds. Choose the drain to suit access: this configuration has an automatic drain, which suits installations that are not checked daily; manual and differential-pressure drains are available on other codes. The 5 um element (code W) is the finer of the two published grades, chosen over the standard 40 um where downstream equipment is more sensitive to particulate. The fitted round gauge reads in psi; square gauges and MPa or bar scales can be ordered. The T in the code sets the thread to NPT; PT is the standard thread and G is also a catalogue option. A mounting bracket is included.
One honest note before ordering: flow for this series is published as curves, not as a single rating, so there is no one rated-flow number to quote. Ask us to confirm sizing against your application and we will check the datasheet curves with you before you order.
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 there is no one rated-flow number we can quote for this unit. What we can state from the catalogue is the decoded specification: 1 in NPT port, 5 um filtration, automatic drain, standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a maximum inlet pressure of 1.0 MPa (145 psi). Contact us and we will confirm the datasheet and flow curves for your application before you order.
The A in the code sets the automatic drain: the bowl expels collected condensate on its own, which suits installations that are not checked every day, whereas manual and differential-pressure drain options are available on other codes. The K at the end of the code means a reverse/check valve is fitted, so air cannot flow back through the unit toward the supply side. The W sets the finer 5 um filter element instead of the standard 40 um, and the C2 fits a round external gauge reading in psi.
