The AirTAC GFR60025AC2TK 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 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 GFR60025AC2TK is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is built around a 1 in NPT port, so it sits directly in a 1 inch main line where a single device must both clean the air and set the working pressure. The automatic drain bleeds collected condensate from the bowl without anyone opening it, the 40 um element handles everyday particulate, and the fitted round gauge reads downstream pressure in psi. A reverse/check valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in. Across the range you can order manual or automatic drain, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Cleaning and pressure-setting the 1 in supply main that feeds a spray booth area, where steady regulated pressure and drained condensate protect finish quality.
Feeding the air mains that run case packers, carton sealers and conveyor diverters, holding one set pressure for all the cylinders and valves downstream.
Conditioning the shop-air feed into a machining cell so clamps, tool changers and pneumatic fixtures see clean air at a fixed, repeatable pressure.
Start with the port step: this unit is the 1 in NPT member of the size 600 family, the largest in the GFR range, so it suits main lines rather than drop legs. If your demand is smaller, the same function exists in sizes 200 to 400 with 1/8 to 3/4 in ports. Drain choice matters in practice: automatic drain (this unit) suits unattended installations, manual drain suits stations someone walks past, and the differential-pressure default drains only when the pressure drop calls for it. The standard element is 40 um; order the W variant if you need 5 um. Gauges come as an embedded square unit or an external round one, with MPa, psi or bar scales - this configuration carries a round psi gauge.
Thread is the other real decision: PT is the catalogue standard, while G (BSPP) and NPT (this unit) are order options, so match the thread to your pipework rather than adapting it. A bracket is included for panel or wall mounting. One honest note before you order: AirTAC publishes flow as curves, not a single rated figure, so send us your line size and demand and we will confirm sizing from the datasheet.
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 this series as curves, not as a single rated number, so we do not quote one. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The A position selects the automatic drain, which expels collected condensate from the bowl by itself instead of waiting for a manual bleed - useful on mains that run unattended. The K means a reverse/check valve is fitted, and the 2 selects the psi gauge scale.
