AirTAC GFR600-25 Filter Regulator (GFR60025C1WK)
The AirTAC AirTAC GFR600-25 Filter Regulator (GFR60025C1WK) is a genuine G-series filter regulator: water separation, 5 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.

About the AirTAC GFR600-25 Filter Regulator (GFR60025C1WK)
The AirTAC GFR60025C1WK is a 600-size filter regulator with filtration and pressure regulation combined in one body. This build pairs the 5 um fine filter element (W) with a fitted reverse (check) valve (K), on a 1 in. PT port with a differential-pressure drain in the aluminium alloy bowl and a round MPa-scale gauge. Maximum working pressure is 1.0 MPa (145 psi); the regulating range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. Within the GFR series you can order the same size with a standard 40 um element, without the check valve, with automatic or manual drains, and with G (BSPP) or NPT threads, so the configuration can be tuned to each line. Flow is published as curves rather than a single rating; we confirm the datasheet figures for your application on request.

Model Code: AirTAC GFR600-25 Filter Regulator (GFR60025C1WK)
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

- GFR600PT3/4" - PT1"
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.

Where the AirTAC GFR600-25 Filter Regulator (GFR60025C1WK) Is Used
Foundry moulding machine air circuit
Conditioning the compressed air feeding a foundry moulding machine's clamp and core-shoot circuits, where the 5 um element and check valve protect the circuit in a dusty, demand-heavy corner of the plant.
Pneumatic press and fixture circuit
Installed ahead of a pneumatic workholding press, it filters and regulates the supply to the clamp cylinders, with the check valve fitted on the outlet and the 5 um element guarding the directional valves.
Maintenance-shop multipoint air drop
Serving a heavy-vehicle maintenance shop's main workbench air drop, it gives technicians filtered, regulated air at a set pressure for impact tools and lifting bags, with fine filtration for the shop's calibrated tools.
Is the AirTAC GFR600-25 Filter Regulator (GFR60025C1WK) the Right Unit?
This code is the fine-filtration, check-valve build of the 600 size on a 1 in. PT port. Drop the K if you do not need the check valve, or the W if 40 um filtration is sufficient - each choice is a separate catalogue code rather than a modification. Drain is the differential-pressure default here; automatic (A) and manual (M) versions are orderable. Gauge is the round MPa type, with psi (2) and bar (3) scales available.
If a 1 in. port is larger than the machine needs, the same configuration exists in sizes 200, 300 and 400. Thread alternatives are G (BSPP) and NPT; J removes the bracket. As flow for this series is given as curves, not a single rated figure, ask us to confirm sizing from the datasheet against your consumption before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR600-25 Filter Regulator (GFR60025C1WK) FAQ
AirTAC publishes flow for the GFR600 series as characteristic curves rather than one rated figure, so we do not quote a single number. Give us your inlet pressure, set pressure and air consumption and we will read the datasheet curve with you and confirm the 600 size and 1 in. port are correctly sized before you order.
K indicates that a reverse (check) valve is fitted in this unit. Yes - the same 600-size filter regulator is available without the check valve: the GFR60025C1W is identical apart from that fitting. You can also choose the 40 um element instead of the 5 um one, an automatic or manual drain instead of the differential-pressure drain, and G (BSPP) or NPT threads instead of PT.
