The AirTAC GFR600C25AF2TK AirTAC Filter Regulator NPT 1 in 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 GFR600C25AF2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This 600-size unit is threaded 1 in NPT, drains condensate automatically, filters to the standard 40 um grade, and carries a reverse/check valve so regulated downstream pressure is held if upstream supply is interrupted. The embedded square gauge reads in psi, the aluminium alloy bowl suits this largest frame, and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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, and options include manual or differential-pressure drains, a 5 um filter element (code W), MPa or bar gauge scales, an external round gauge, and G (BSPP) or NPT threads in place of the PT standard. Flow for this size is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against 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 at the drop point where the plant air main feeds a production cell, it removes water and pipe scale from the main supply and holds a steady regulated pressure for every tool and actuator on that cell, with automatic drain-off so condensate is removed without an operator round.
On a packaging or conveyor line with many small cylinders and air-driven diverters running all shift, the unit gives one filtered, regulated supply point for the whole line, and the check valve keeps the set pressure stable at the line if the header pressure dips.
Feeding positioners and pilot-air circuits on large automated valves, it delivers clean air at a fixed pressure so valve stroking stays consistent, with the 40 um element protecting the pilot components and the psi gauge giving operators a direct local reading.
Step through the real choices before ordering. Size 600 with a 1 in port is the largest frame in the GFR range; if your line flow is modest, a 300 or 400 with a smaller port may be the better match, and we can check the published flow curves against your demand. Drain: this unit is automatic (code A), which suits unattended installations; manual (M) and differential-pressure (blank) versions exist. Filter grade: 40 um standard here, or 5 um with code W if finer protection is needed. Gauge: the embedded square gauge is fitted in a psi scale; MPa or bar scales and an external round gauge are alternatives. Thread: this code is NPT; PT is the standard and G (BSPP) can be ordered. A mounting bracket is included, and the reverse/check valve (K) is fitted on this unit.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet curve and sizing 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 family as curves, not as a single rated figure, so we do not state a flow number here. Send us your line pressure, required downstream pressure and expected air demand, and we will confirm the datasheet curve for this 600-size, 1 in NPT unit and check it against your application before you order.
Code A in the model gives the automatic drain, which ejects collected condensate without manual attention - useful where the unit is mounted in a less accessible spot. The K code fits a reverse/check valve that holds the regulated downstream pressure if upstream supply is lost. Both are order-time choices: manual (M) and differential-pressure drains, and a version without the check valve, are available in the same series, along with a 5 um element (W), other gauge scales, and G (BSPP) or NPT thread.
