The AirTAC GFR600C25AC1WT AirTAC Filter Regulator 1 in NPT, 5 um 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 GFR600C25AC1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in one body. This 600-size unit is built for 1 in NPT threads, carries a 5 um filter element (code W, against the 40 um standard), drains condensate automatically, and comes with a round gauge scaled in MPa. The regulator is the standard type, adjustable from 0.15 to 0.9 MPa (20-130 psi), and a mounting bracket is included. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 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 to 1 in, and the same frame can be ordered with a manual or differential-pressure drain, a 40 um element, an embedded square gauge or an external round gauge scaled in MPa, psi or bar, G (BSPP) or NPT threads in place of the PT standard, and a reverse/check valve. Flow for this unit is published as a curve rather than a single rated figure, so ask us to confirm the datasheet numbers 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.

Mounted where the 1 in main enters a CNC machining cell, it removes water and particles down to 5 um and holds a steady pressure for clamps, fixtures and tool-changer cylinders.
Feeding large quarter-turn valve actuators at a water treatment plant, it filters the plant air to 5 um and regulates it to the actuator set point, while the automatic drain clears condensate on its own.
On a parcel-sortation conveyor, it conditions and regulates the air driving diverter and stopper cylinders along the 1 in header, with the round MPa gauge giving operators a local set-point reading.
Size and port: 600 is the largest GFR frame and this unit carries a 1 in port; step down to 200, 300 or 400 (1/8 to 3/4 in) when your demand is smaller - we can check the flow curve against your consumption before you order. Drain: this unit drains automatically; manual and differential-pressure drains are the alternatives on the same frame. Filtration: the 5 um element here (code W) suits downstream valves and instruments; the 40 um standard element is the economical choice for general shop air. Gauge: a round gauge scaled in MPa is fitted; an embedded square gauge and psi or bar scales are options. Thread: NPT here; PT is the AirTAC standard and G (BSPP) is also catalogued. A mounting bracket is included. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
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 flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line size and air consumption and we will confirm the flow data from the datasheet for this exact unit on request.
The W in the code orders the 5 um element instead of the 40 um standard, for finer protection of valves and instruments, and the A orders an automatic drain that expels condensate without manual attention. Manual and differential-pressure drains, and the 40 um element, remain available on the same GFR600 frame.
