The AirTAC GFR600C25AF2K AirTAC Filter Regulator 1 in PT 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 GFR600C25AF2K is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 configuration carries a PT1 (1 in) port, 40 um standard filtration, an automatic drain that ejects collected condensate without manual attention, a built-in check valve (code K) that blocks backflow, and an embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi); the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing, and the size 600 bowl is aluminium alloy.
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, an optional 5 um element (code W), gauge scale options in MPa, psi or bar, and G (BSPP) or NPT thread variants to order. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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 the air drop to a paint booth: the 40 um element strips water and pipe-scale that would ruin finish quality, while the regulator holds a steady setting at the booth and the automatic drain clears condensate between shifts without an operator visit.
Serving the cylinder group on a carton-forming conveyor: the regulator pins working pressure so case clamp and pusher cylinders behave consistently, the check valve holds the setting if upstream supply dips, and the 1 in port matches a main header take-off.
Conditioning the supply to a machining centre's fixture clamps: clean, moisture-reduced air protects the clamp cylinders, the psi gauge gives the setter a direct readout at the machine, and the automatic drain suits an unmanned cell.
Work through the decodable choices in order. Size and port: 600 is the largest step in the GFR range and this unit takes a PT1 (1 in) port - choose it when your circuit sits at the top of the range's flow demand, and let us check the published flow curve against your consumption first. Drain: this unit is automatic, ideal where the unit is visited infrequently; manual and differential-pressure drains are available alternatives. Filtration: 40 um is standard here; specify 5 um (code W) when downstream equipment needs finer protection. Gauge: the embedded square gauge on this unit reads psi, with MPa and bar scales and an external round gauge available as options. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included.
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 this series as curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line pressure and air consumption and we will confirm the sizing from the datasheet curves on request before you order.
This configuration carries code A, the automatic drain, which discharges collected condensate on its own - the right choice where the unit is mounted in a rarely visited spot. The same family is also available with a manual drain for supervised draining or a differential-pressure drain that responds to the load; those are separate order codes.
