AirTAC GFR400-10 Filter Regulator (GFR40010LJF1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010LJF1) 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 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 (GFR40010LJF1)
GFR40010LJF1 is an AirTAC G-series filter regulator: clean-up and pressure regulation in one body. This decode is the 400 frame with a 3/8 in PT port, in the low-pressure type, with the standard 40 um element and the default differential-pressure drain. J omits the mounting bracket, and F1 keeps the embedded square pressure gauge with an MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature window is -5 to 70 C (non-freezing), and the adjusted outlet range for a differential-pressure drain unit is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part from a family offered in 200, 300, 400 and 600 frames with PT, G (BSPP) or NPT threads, 40 um standard or 5 um fine elements, differential-pressure, automatic or manual drains, and square or round gauges in MPa, psi or bar scales; the 400 bowl is polycarbonate. AirTAC publishes flow as characteristic curves rather than one rated figure, so ask us to confirm the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (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. |
| (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. |

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 (GFR40010LJF1) Is Used
Packaging valve island
Feeding a control-panel valve island on a packaging machine, the unit strips condensate and holds a constant supply pressure so solenoid valve stations behave identically across shifts.
Dock door actuators
At a distribution centre, the regulator conditions the air driving dock-door and leveler cylinders, keeping door cycle pressure steady as the compressor room load changes.
Weld fixture clamping
On a robotic weld cell fixture, the unit supplies clean, regulated air to swing clamps, so clamp force stays consistent from first piece to last.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010LJF1) the Right Unit?
Match the 200/300/400/600 frame to your port and air demand; this 400 code carries a 3/8 in PT port. For drainage, differential-pressure (this code) is the unattended default, automatic suits continuously running lines, and manual fits intermittent duty with a wider adjusted range of 0.05-0.9 MPa (7-130 psi). The 40 um element is the standard grade; add W for 5 um fine filtration. This code omits the bracket (J) for direct in-line or manifold mounting and uses the embedded square gauge in MPa; the round external gauge and psi or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT available as catalogue options. Flow is published as curves, not a single rating, so 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. 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 (GFR40010LJF1) FAQ
AirTAC publishes G-series flow as characteristic curves rather than a single rated figure, so we cannot state one number honestly. Give us your line pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet curve and sizing on request.
PT is the standard thread on this code, as decoded here. G (BSPP) and NPT are catalogue options you specify when ordering, which is useful if your piping follows European or US parallel-thread standards respectively.
