The AirTAC GFR600C25F2T AirTAC Filter Regulator 1 in NPT 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 GFR600C25F2T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, so one unit does the job of a filter and a regulator without a separate joint between them. This size 600 configuration has a 1 in NPT port for high-flow main lines, 40 um standard filtration, a differential-pressure drain that bleeds collected condensate automatically as pressure across the bowl changes, and an aluminium alloy bowl, which is the bowl material used at size 600. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, an embedded square gauge with a psi scale is fitted, a mounting bracket is included, and the working temperature range is -5 to 70 C (non-freezing) at up to 1.0 MPa (145 psi) maximum inlet pressure.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (code W) filtration, gauge scales in MPa, psi or bar, and low- or standard-pressure regulator types. Flow figures for this family are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Installed at the drop from a compressed-air ring main, the 1 in NPT port and 40 um element clean the supply while the regulator holds a steady set pressure to every machine station downstream, with the differential-pressure drain keeping condensate out of the distribution piping.
Feeding the pneumatic cylinders and air-actuated gates of a carton packaging conveyor, the unit filters incoming air and holds the actuator circuit at a fixed pressure so case-clamp and pusher strokes stay consistent through the shift.
Mounted where the overhead drop serves impact wrenches and pneumatic nutrunners on an assembly line, the filter regulator strips water and scale before the tools and keeps supply pressure where the tool manufacturer specifies, with the square psi gauge giving operators a direct readout.
Start by matching the size and port to the air demand of the line: the GFR range steps through sizes 200, 300, 400 and 600, with larger sizes carrying larger ports (06 to 25, i.e. 1/8 in to 1 in) and more flow capacity, so a 1 in NPT port at size 600 suits a plant main or a large machine header. Then pick the drain: differential-pressure (the default on this model) needs no operator attention, automatic drain (code A) empties the bowl on its own cycle, and manual drain (code M) is emptied by hand. Choose 40 um standard filtration or 5 um (code W) where finer protection is needed, and select the gauge scale - MPa, psi or bar - to match the instruments your team reads. Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket can be included or omitted (code J). Because flow for this family is published as curves rather than a single rated figure, 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line demand and we will confirm the correct size against the datasheet curves on request before you order.
This model has the differential-pressure drain as standard: condensate collected in the bowl is discharged automatically as the pressure differential across the bowl changes, with no manual intervention. If your application needs a different arrangement, the family also offers automatic drain (code A) and manual drain (code M) versions - note the regulation range differs by drain type, with manual-drain versions covering 0.05-0.9 MPa (7-130 psi).
