The AirTAC GFR60025F2TK 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 PT1" 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 GFR60025F2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is configured with a 1 in NPT port, 40 um standard filtration, a differential-pressure drain, and a reverse/check valve fitted. The embedded square gauge is scaled in psi, and the aluminium alloy bowl suits this largest frame size. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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.

Installed at the take-off from a 1 in compressed-air distribution header, the GFR60025F2TK filters water and particulate from the plant supply and holds a set downstream pressure for the whole distribution leg it feeds.
Feeding the valve manifolds and air cylinders of a packaging or bottling conveyor, the unit delivers cleaned, regulated air so actuators see a stable supply pressure, while the differential-pressure drain sheds collected condensate during production.
Mounted on a large pneumatic control or process panel with the included bracket, the filter regulator conditions the air feeding pilot valves and instrumentation circuits, with the psi-scaled square gauge giving operators a direct setpoint readout.
Choose the size and port step against the air demand of the circuit: the 600 frame with its 1 in NPT port is the largest GFR option, so it suits high-consumption headers and main-line drops rather than point-of-use drops served by 200/300/400 units. This configuration carries the 40 um standard element; specify the W variant if the 5 um grade is required. Drain choice matters: differential-pressure drain (as fitted here) discharges automatically as flow passes, while automatic (A) or manual (M) drains suit different service patterns. The square gauge is scaled in psi here; MPa and bar scales are available, and an external round gauge is optional. Thread is NPT on this unit; PT is the standard thread and G is also a catalogue option. A mounting bracket is included, and the K code confirms a reverse/check valve is fitted. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow data from the datasheet so you can size the unit against your air demand before ordering.
The blank drain position in the code means a differential-pressure drain is fitted: it discharges collected condensate automatically as air flows through the unit, with no operator action. If your service pattern suits it, the GFR600 series is also available with an automatic drain (code A) or a manual drain (code M); note the regulation range differs by drain type, with manual-drain versions covering 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for this differential-pressure configuration.
