The AirTAC GFR60025F3TK AirTAC Filter Regulator 1in NPT, Bar Gauge 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 AirTAC GFR60025F3TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is supplied with a 1 in NPT port, a 40 um filter element, a differential-pressure drain, an embedded square gauge scaled in bar, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Because this is the 600 size, the bowl is aluminium alloy; operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in 200, 300, 400 and 600 sizes with a choice of ports, drain types, 40 um or 5 um filtration, gauge scales and thread options, so a matching unit can be specified for most lines. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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 large plant air header to clean the supply and hold a steady working pressure for a production hall's distribution manifold.
Feeding a bank of directional valves and air cylinders on an automated machine, keeping water and scale out of the valves while the set pressure holds them within their rated range.
Conditioning the air that drives conveyor diverters, clamps and packaging heads, with the check valve holding the downstream circuit if the supply line is momentarily lost.
Step up or down through the 200/300/400/600 sizes to match the port and flow your line needs; this unit sits at the top of the range with a 1 in NPT connection. Choose the drain to suit access: differential-pressure (this unit, drains as pressure drops), automatic for unattended duty, or manual where you want controlled blows-down. Filter grade is 40 um standard here; specify 5 um (code W) if downstream valves or instruments need finer protection. The square gauge is fitted and scaled in bar; MPa or psi scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options - this unit is coded NPT. A bracket is included, and the K code adds a reverse/check valve. Flow is published as curves, not a single rating, so send us your application 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 GFR series as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the flow from the datasheet curves on request before you order.
K means a reverse (check) valve is fitted. It holds pressure in the downstream circuit if the inlet supply is interrupted, which protects set pressures on cylinders and valves. Units without the K code have no check valve. This unit also carries a square gauge scaled in bar, a 40 um element and a differential-pressure drain.
