AirTAC GFR400-10 Filter Regulator (GFR40010JNWK)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010JNWK) 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 PT3/8" 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 GFR400-10 Filter Regulator (GFR40010JNWK)
The AirTAC GFR40010JNWK is a filter regulator in one body: it removes water and particulate from the compressed-air line and regulates downstream pressure, with a drain bowl to collect condensate. This 400-size configuration has a 3/8in PT port, the W-coded 5 um filtration element instead of the standard 40 um, no mounting bracket (J code) and no gauge (N code). The K code adds a built-in reverse (check) valve. Maximum working pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and as a standard-type unit with differential-pressure drain the regulator adjusts between 0.15 and 0.9 MPa (20-130 psi). The bowl is PC (polycarbonate) at this size.
This is a genuine AirTAC part from the G series, sold here in the US market. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in filter, regulator, lubricator and combination formats, with your choice of drain type, filter grade, gauge, thread (PT standard; G and NPT orderable) and bracket. Because AirTAC publishes flow for this series as performance curves rather than a single rated figure, we confirm exact flow and full datasheet values for your application 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.
Model Code: AirTAC GFR400-10 Filter Regulator (GFR40010JNWK)
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (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. |
| J | Supplied without bracket. |
| 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. |
| (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.
Size Class

- GFR400PT3/8" - PT1/2"
- 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 GFR400-10 Filter Regulator (GFR40010JNWK) Is Used
Pneumatic valve stands on a bottling line
Feeding a bank of directional control valves that actuate fill, capping and reject cylinders: the 5 um element protects spool fits from particulate, and the check valve holds the set circuit against backflow when the supply is shut off.
Pneumatic clamping on a CNC turning cell
A regulated 3/8in feed to chuck and clamp actuators: the regulator holds a steady downstream setpoint so clamp force stays repeatable, while the filter strips water and fine particles before they reach the actuator seals.
Air-assisted transfer gates on a packaging conveyor
Regulated air for pop-up diverters and pusher cylinders along a conveyor line: the 5 um grade suits the small pilot valves these gates use, and the built-in check valve prevents downstream air from pushing back through the unit at line stop.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010JNWK) the Right Unit?
Size 400 with a 3/8in PT port sits in the upper-middle of the G series range: step down to 300 or 200 for smaller ports and lower flow, or up to 600 where larger ports are needed. Match size to the flow your line requires - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The W code selects 5 um filtration, suited to feeding valves, cylinders or instruments; omit it for general 40 um service. The drain here is the standard differential-pressure type; automatic and manual drains are orderable variants. This unit is specified without gauge (N) and without bracket (J), and the K code means a reverse/check valve is fitted - useful where backflow at shutdown must be blocked. PT is the standard thread; G and NPT are orderable options.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR400-10 Filter Regulator (GFR40010JNWK) FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so we do not quote one number here. Ask us and we will confirm the flow and full datasheet figures for this 3/8in, 5 um unit against your application before you order.
J omits the mounting bracket (blank would include one), N means no gauge is fitted, W selects the 5 um filtration element instead of the standard 40 um, and K fits a reverse (check) valve in the body. The drain is the standard differential-pressure type, and PT is the standard thread with G and NPT available to order.
