AirTAC GFR400-10 Filter Regulator (GFR40010AF1W)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010AF1W) 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 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.

About the AirTAC GFR400-10 Filter Regulator (GFR40010AF1W)
The GFR40010AF1W is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body. This 400-size unit is specified for 3/8 in PT ports, with an automatic drain that discharges collected condensate from the PC bowl without operator attention, a 5 um (W) filtering element for finer air cleanliness than the standard 40 um grade, and an embedded square pressure gauge scaled in MPa. The regulated outlet is set anywhere in the 0.15-0.9 MPa (20-130 psi) range against a 1.0 MPa (145 psi) maximum inlet.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with PT, G (BSPP) and NPT thread options, differential-pressure, automatic or manual drains, and 40 um or 5 um elements. The 400-size bowl is polycarbonate (PC), and the operating temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow data as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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 (GFR40010AF1W)
| 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". |
| 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). |
| F | Gauge shape: Square. 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. |

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 (GFR40010AF1W) Is Used
Spray-booth atomizing air
Regulating atomizing air to spray guns on a finishing line, where 5 um filtration helps keep nozzles clear and the automatic drain copes with condensate from humid compressor air.
CNC machine clamping circuits
Supplying clean, regulated air to tool-clamp and chip-door cylinders on a machining center, with the square MPa gauge letting setters read line pressure at a glance.
Packaging conveyor diverters
Controlling air to diverter and pusher cylinders on a packaging conveyor line, with the automatic drain so the bowl does not need daily manual attention.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010AF1W) the Right Unit?
The 400 size is the second-largest step of the G range; move to 300 or up to 600 to match the port and flow path your line needs. Drain choice: automatic (this code, A) empties the bowl by itself, manual (M) needs operator action, and the series default is the differential-pressure type. Filter grade: 5 um here versus the 40 um standard - choose 5 um where downstream valves and cylinders need finer air. Gauge: embedded square with MPa scale (F1); psi (2) and bar (3) scales and an external round gauge are the other catalogue choices. Thread: PT is the standard; G and NPT are orderable options. Flow is published as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC GFR400-10 Filter Regulator (GFR40010AF1W) FAQ
AirTAC publishes filter-regulator flow as performance curves rather than a single rated figure, so no one number is quoted here. Send us your required flow and working pressure and we will confirm the datasheet curve and sizing for your application on request.
A = automatic drain, F1 = embedded square gauge scaled in MPa, and W = the finer 5 um filter element (40 um is the standard grade). The 10 gives a 3/8 in PT port and 400 is the body size.
