AirTAC GFR400-10 Filter Regulator (GFR40010AJC1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010AJC1) is a genuine G-series filter regulator: water separation, 40 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 (GFR40010AJC1)
The GFR40010AJC1 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 the series-default differential-pressure drain, the standard 40 um filter element for general plant air, and an external round pressure gauge scaled in MPa. The J code means no mounting bracket is supplied, so the unit mounts directly on your own plate or manifold arrangement. 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.
It is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with PT, G (BSPP) and NPT threads, differential-pressure, automatic or manual drains, and 40 um or 5 um (W) elements. The 400-size bowl is polycarbonate (PC) and the operating temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow as curves rather than a single rating, so we 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 (GFR40010AJC1)
| 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 (GFR40010AJC1) Is Used
Conveyor stopper and lift controls
Regulating air to stopper, lift and gate cylinders along a conveyor line, with the round MPa gauge mounted where operators can read it directly at the machine.
Plant branch-air regulation
Setting branch pressure off a factory ring main for general-purpose tool and actuator air, where the standard 40 um element suits everyday plant supply.
Fixture-clamping bench
Supplying regulated air to clamp cylinders on a weld-and-assembly fixture bench built on the shop's own mounting plate, since this J-coded unit ships without a bracket.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010AJC1) the Right Unit?
Drain type is the key choice here: this code carries the default differential-pressure drain, while the A code gives an automatic drain and M gives manual operation - pick automatic where bowls are hard to reach. Filter grade: the 40 um standard here, or the W code for 5 um where downstream equipment needs finer air. Gauge: this version pairs the regulator with an external round gauge in MPa (C1); an embedded square gauge in MPa, psi or bar is the alternative. The J code omits the bracket - order the plain code if you need the bracket included. Thread: PT is the standard; G and NPT are orderable options. Flow is published as curves, not a single rated figure, so share your duty 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 (GFR40010AJC1) FAQ
Flow for this filter regulator is published as performance curves, not a single rated figure, so no one number is stated here. Send us your required flow, port size and working pressure and we will confirm the datasheet curve and sizing for your application on request.
J = no mounting bracket included, C1 = an external round gauge scaled in MPa, and with no drain letter the unit carries the series-default differential-pressure drain (A or M would give automatic or manual). The 400/10 gives a 3/8 in PT port and with no W the filter grade is the standard 40 um.
