AirTAC GFR600-25 Filter Regulator (GFR60025NWK)
The AirTAC AirTAC GFR600-25 Filter Regulator (GFR60025NWK) 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 (GFR60025NWK)
GFR60025NWK is an AirTAC G-series filter regulator: a water-and-particulate filter and a pressure regulator built into one body. This 600-size unit carries a PT1" port and the 5 um (W) element for finer filtration than the standard 40 um grade. The drain is the default differential-pressure type, the gauge position is left empty (code N), and a reverse (check) valve is fitted (code K). With this drain type the regulated output is adjustable over 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), the 600-size bowl is aluminium alloy, and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is also available in 200, 300 and 400 sizes with 1/8" to 3/4" ports, PT (standard), G (BSPP) or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um elements, bracket options, and embedded square or external round gauge variants. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm sizing and datasheet figures on request.

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.

| 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Where the AirTAC GFR600-25 Filter Regulator (GFR60025NWK) Is Used
Structural steel shot-blast cabinet
Sits on the 1" main line feeding a blast cabinet, cleaning water and fine debris out of the air before it reaches the deadman valve, hose couplings and nozzle, while holding the working pressure steady at a set point.
Injection moulding machine air supply
Regulates plant air on the service line that drives core-pull cylinders, ejector valves and part-blow-off nozzles, with the 5 um element protecting the machine's solenoid valves from condensate and swarf.
Bottling line actuation header
Installed on the main header supplying bottle-gripper and stopper cylinders on a filling line; the differential-pressure drain passes accumulated condensate during production and the check valve accommodates back-flow in the circuit.
Is the AirTAC GFR600-25 Filter Regulator (GFR60025NWK) the Right Unit?
Size and port: 600 is the largest G-series size, here with a 1" PT port; step down to 400 (3/4"), 300 (1/2", 3/8") or 200 (1/4", 1/8") when the flow demand is smaller. Drain: this code keeps the default differential-pressure drain; order the A (automatic) or M (manual) variant instead, and note that the manual-drain version widens the adjustment range down to 0.05 MPa. Element: 5 um here; 40 um is the standard grade. Gauge: none in this code; square embedded or round external gauges with MPa, psi or bar scales are the alternatives. Reverse valve: K fits a check valve; omit K for none. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options, and the J code removes the bracket. AirTAC publishes flow as curves, not a single rating, so ask us to confirm sizing against the curves for your application 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 (GFR60025NWK) FAQ
AirTAC publishes flow for the GFR600 series as curves, not as a single rated figure, so quoting one number here would be guesswork. Tell us your line pressure, set pressure and demanded flow, and we will confirm sizing against the datasheet curves on request.
The N in GFR60025NWK means the gauge position is empty; catalogue versions with an embedded square gauge or an external round gauge in MPa, psi or bar scales can be ordered instead. W is the 5 um filter element (versus the 40 um standard), and K means a reverse (check) valve is fitted. The drain on this code is the default differential-pressure type.
