The AirTAC GFR600C25AC2K AirTAC Filter Regulator, PT1 in, 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 AirTAC GFR600C25AC2K is a size 600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration carries a PT1 (1 in) port, a 40 um standard filtration element, an automatic drain that expels collected condensate without manual attention, and a reverse/check valve (code K) fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the round external gauge is fitted with a psi scale. At size 600 the bowl is aluminium alloy, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (code W) filtration, manual or differential-pressure drain alternatives, G or NPT thread options, and gauge scale choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeding regulated, water- and particulate-filtered air to spray booths and air-assisted equipment on a paint line, where the automatic drain keeps condensate off the work without an operator stopping by.
Supplying a set pressure to conveyor stopper and gripper cylinders on a filling line, with the 1 in port serving a high-consumption header and the check valve holding the circuit if supply dips.
Protecting solenoid valves and actuators on a machining centre by filtering incoming shop air to 40 um and holding the manifold at the pressure the machine controls expect.
Start with the port and size step: this unit is the largest in the GFR range at 1 in PT, sized for high-demand circuits - if your consumption is modest, a 400 or 300 size may suffice, and we can confirm the flow curves against your requirement. Drain type is a real choice: automatic (as fitted here) suits unattended duty, while manual and differential-pressure versions are available. Filtration is 40 um standard; specify code W for 5 um where finer protection is needed. The gauge here reads psi; MPa and bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here - ask us to confirm sizing against your application 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 GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow curve and check the sizing for you on request.
This unit carries code A: an automatic drain that discharges collected condensate without operator attention, useful on unattended or high-humidity installations. The GFR family also offers manual drain (code M) and the differential-pressure drain as the default, and the regulator range for the automatic-drain version is 0.15-0.9 MPa (20-130 psi).
