AirTAC GFR400-10 Filter Regulator (GFR40010AJC1WK)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010AJC1WK) 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 (GFR40010AJC1WK)
The AirTAC GFR400 series is a genuine AirTAC filter regulator, combining filtration and pressure regulation in a single body. This GFR40010AJC1WK configuration is a 400-size unit with 3/8 in PT (thread type) ports, a 5 um fine-filter element (W), an automatic drain, an external round pressure gauge on the MPa scale, and a reverse (check) valve fitted at the outlet. Maximum inlet pressure is 1.0 MPa (145 psi); with automatic drain the standard setting range is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing, and the 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part supplied for the US market. The G series runs from size 200 to 600, with 40 um standard or 5 um elements, three drain types, square or round gauges in MPa, psi or bar scales, reverse-valve or plain outlets, and G (BSPP) or NPT threads to order. Flow is published as curves rather than one rated figure, so we confirm the datasheet and flow 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 (GFR40010AJC1WK)
| 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. |
| J | Supplied without bracket. |
| (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.

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 (GFR40010AJC1WK) Is Used
Robotic weld cell clamp circuits
Supplies regulated air to gun-clamp actuators in a robotic welding cell, with the check valve holding clamp force if the plant air header drops.
Trailer air preparation point
Conditions air at a maintenance-bay drop for actuated test rigs on trailers, keeping the 5 um element between the shop header and fine pilot valves.
Machine-tool spindle air seal feed
Delivers clean, steady regulated air to air-seal and purge ports on a spindle, with automatic drain protecting the narrow passages from moisture.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010AJC1WK) the Right Unit?
This code bundles the fine 5 um element (W), automatic drain (A), round MPa gauge (C1), check valve (K) and no bracket (J) on a 400-size body with 3/8 in PT ports - a strong pick for circuits that need both fine filtration and pressure retention. If your particles are coarser and cost matters, the 40 um standard grade is available; if an operator drains the bowl on a schedule, choose manual (M). Gauge scale options are psi and bar as well as MPa. PT is the standard thread; G (BSPP) and NPT versions are catalogue options to order, and a mounting bracket can be added since none is included here. Flow appears in the catalogue as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 (GFR40010AJC1WK) FAQ
Flow for the GFR400 series is published as curves rather than a single rated number, so we cannot state one rated figure. Share your inlet pressure, setpoint and demand, and we will confirm the datasheet and flow-curve figures on request before you order.
K fits a reverse (check) valve that holds downstream pressure when the supply fails; W selects the 5 um fine-filter element instead of the 40 um standard grade. Combined with automatic drain and the round MPa gauge, this code defines a fine-filtering, pressure-retaining 3/8 in PT filter regulator.
