AirTAC GFR400-10 Filter Regulator (GFR40010AJF1WK)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010AJF1WK) 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 (GFR40010AJF1WK)
The GFR400-10 pairs filtration and pressure regulation in one AirTAC G-series body on a 3/8" PT (standard thread) connection at size 400. This top-spec configuration combines the finer 5 um filter element (W), an automatic drain that clears condensate on its own, an embedded square pressure gauge with MPa scale, and a fitted reverse (check) valve that helps hold downstream pressure against supply interruptions. Outlet pressure adjusts over 0.15-0.9 MPa (20-130 psi) in the automatic-drain configuration.
This is a genuine AirTAC part. The GFR series runs from size 200 to 600 with selectable ports, drains, filter grades, gauges, threads (PT/G/NPT) and the K check-valve option. Medium is compressed air only; max working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. Flow is published as curves, not a single rating, so we confirm datasheet and sizing 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.

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 (GFR40010AJF1WK) Is Used
Bottling line actuation
Feeding cylinder-driven gates and reject fingers on a bottling conveyor, it delivers clean, regulated air while the check valve helps hold circuit pressure during brief supply fluctuations.
Textile machine air circuits
On weaving or spinning machines with many small pneumatic functions, the 5 um element protects fine jets and valves and the regulator keeps actuation pressure stable across the frame.
Automated fastening stations
Supplying pneumatic torque and press-fit tools at an assembly station, it maintains the set working pressure shown on the square MPa gauge and resists backflow effects from cycling tools.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010AJF1WK) the Right Unit?
This variant bundles the choices that matter most in one code: 5 um filtration for cleaner downstream air, automatic drain for unattended bowls, square MPa gauge for direct setting, and the K check valve where pressure retention downstream is wanted. Size 400 with the 3/8" PT port matches lines built to that port; larger or smaller duties step to the 600 or 200/300 sizes. If the check valve is not needed, the same unit is offered without K. PT is the standard thread; G (BSPP) and NPT are orderable options. Bracket: J = not included. Since AirTAC publishes flow as curves rather than one rated number, send us your duty point and we will confirm sizing from 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR400-10 Filter Regulator (GFR40010AJF1WK) FAQ
AirTAC publishes flow for the G series as curves rather than a single rated figure, so no one number is quoted here. Give us your working pressure and air consumption and we will confirm the curve and full datasheet for this 5 um, check-valve configuration on request.
K means a reverse (check) valve is fitted in the unit, which helps prevent downstream pressure from being lost back toward the supply side. If your circuit does not need that function, the same GFR400-10 is available without K - a straightforward decode choice rather than a performance difference.
