The AirTAC GFR600C25AC2W AirTAC Filter Regulator PT1 5 um Auto Drain 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 GFR600C25AC2W is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a 1 in PT port, suited to the largest air lines in the range. It carries the fine 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and a round external gauge reading in psi so the set pressure is visible at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.15 to 0.9 MPa (20-130 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, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Installed on the 1 in main distribution line feeding a production hall, the GFR600C25AC2W removes water and fine particles and holds a steady regulated pressure for every downstream drop, with the automatic drain keeping condensate off the floor.
Fitted ahead of a heavy pneumatic press or clamping station, this unit cleans the supply and lets the operator set and read the working pressure on the round psi gauge, protecting cylinders and valves from pressure swings.
On a conveyor system with air-driven diverters and stoppers, the filter regulator supplies clean, regulated air so actuators cycle consistently, while the 5 um element helps keep small control valves from fouling.
Choose the size and port step against the air consumption of the line: this is the 600 size with a 1 in PT port, the largest in the GFR range. The 5 um element (code W) suits applications needing finer particulate removal than the 40 um standard element; the automatic drain is the right choice where the unit cannot be checked regularly, while manual and differential-pressure drains remain available on other codes. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options, and a mounting bracket is included. Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your line size and air consumption and we will confirm the flow and full datasheet figures for this 1 in unit on request before you order.
In the code GFR600C25AC2W, the A sets the automatic drain, which expels collected condensate without manual attention, and the W selects the optional 5 um fine filter element instead of the 40 um standard. The C2 adds an external round gauge reading in psi. All three choices can be specified differently on other GFR600 codes.
