The AirTAC GFR600C25ALC2WTK AirTAC Filter Regulator NPT1 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 GFR600C25ALC2WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body, sized 600 with a 1 in NPT port. This configuration is built for a low-pressure regulated circuit: it carries the 5 um filter element (code W) for finer air cleaning than the 40 um standard element, an automatic drain that expels collected condensate without manual attention, a fitted round gauge reading in psi, and a reverse/check valve (code K) that holds the downstream setting when upstream pressure is lost. At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the flow and 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.

On a beverage canning line, this unit filters and regulates the air feeding gripper and placement cylinders at low regulated pressure, with the automatic drain keeping condensate out of the valves during continuous shifts.
Feeding stopper and divertor cylinders on a packaging conveyor, the 5 um element protects directional valves from particulate while the reverse/check valve holds the regulated setting through upstream dips.
At an automotive paint booth drop, the low-pressure regulator type and 5 um filtration deliver clean, finely regulated air to the spray gun, with the psi gauge giving the painter a direct pressure readout.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - the 600 frame with its 1 in port is the high-flow end of the range. On this unit the drain is automatic, which suits unattended duty; manual and differential-pressure drains are the alternatives if you prefer scheduled or load-linked purging. The 5 um element (code W) is the finer of the two published grades, with 40 um as the standard option. The fitted round gauge here reads psi; square embedded gauges and MPa or bar scales are also available. Thread is NPT on this code, with PT as the catalogue standard and G (BSPP) orderable. A bracket is included.
Because AirTAC publishes flow only as curves and not as a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm sizing against the datasheet curves before you order, including the adjustment range of the low-pressure regulator type, which is not published as a single figure.
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 GFR600 as curves rather than a single rated figure, so we do not quote a flow number. Send us your port size, inlet pressure and target regulated pressure, and we will confirm the flow from the datasheet curves on request before you order.
The L code means the regulator section is the low-pressure variant rather than the standard type, intended for circuits regulated below the standard range. The exact adjustment range for this low-pressure type is not published as a single figure, so we confirm it from the datasheet on request. Everything else on this unit - 1 in NPT port, 5 um element, automatic drain, round psi gauge, reverse/check valve and included bracket - is decoded directly from the model code.
