The AirTAC GFR60025AF3TK 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 PT1" ports, a automatic 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 GFR60025AF3TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around a 1 in NPT port for high-flow main-line duty, an automatic drain that expels collected condensate without daily attention, a 40 um standard filter element, and an aluminium alloy bowl, which is the material used at size 600. The embedded square gauge reads in bar, a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (W) elements, manual or automatic drains in place of the differential-pressure default, MPa/psi/bar gauge scales, and G, NPT or PT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet for 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 1 in main-air drop feeding a production hall, the unit strips water and pipe scale from the compressed air and holds a steady regulated pressure for every downstream branch, with the automatic drain handling condensate between maintenance rounds.
Mounted on the outlet of a compressor receiver, the GFR60025AF3TK filters incoming bulk moisture and particulate and regulates the pressure delivered to the distribution header, while the check valve prevents backflow toward the receiver.
Feeding the valve manifold of a packaging conveyor line, the unit conditions the shop air before it reaches cylinders and actuators, keeping water and debris out of the valves and giving operators a bar-reading gauge to set line pressure at the machine.
Size and port are the first decision: 600 is the largest GFR frame, and this unit's 1 in NPT port suits a plant air drop or compressor outlet where line-sized flow matters - match the port step to the pipe and the flow curve, not to a single number. The automatic drain on this unit suits installs that are not checked daily; manual and differential-pressure drains are the alternatives on other codes. The 40 um element is the standard grade; specify a W code if the application needs 5 um filtration. The fitted square gauge reads bar; MPa and psi scales exist on other codes, and an external round gauge is optional. G and NPT threads are order options alongside the PT standard, and a J code drops the bracket if you do not need it.
Because flow is published as curves and not 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. 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 number, so we do not quote a figure here. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
The A in the code means an automatic drain: collected condensate is expelled from the aluminium bowl without anyone opening it, which suits installations that are not checked daily. Manual-drain and differential-pressure-drain versions are available on other GFR codes if you prefer to drain on a fixed schedule.
