AirTAC GFR400-10 Filter Regulator (GFR40010ALJF1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010ALJF1) 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 (GFR40010ALJF1)
GFR40010ALJF1 is an AirTAC G-series filter regulator, filtering water and particulate from compressed air and regulating downstream pressure in one body. This GFR400 configuration has 3/8 in PT ports, an automatic drain that clears condensate without attention, a 40 um standard element, the low-pressure type regulator, and an embedded square gauge reading in MPa. The J suffix means no mounting bracket is included, for builds where the unit is panel- or manifold-supported. The polycarbonate bowl, 1.0 MPa (145 psi) maximum inlet and -5 to 70 C range suit general compressed-air service.
This is a genuine AirTAC part from the G-series, which covers 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in. Manual and differential-pressure drains, the 5 um element, psi or bar gauge scales, round gauges, G (BSPP) and NPT threads, and bracket-included variants are all catalogue options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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". |
| A | Drain: Automatic 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. |
| (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 (GFR40010ALJF1) Is Used
Assembly cell point-of-use drops
Serves a point-of-use drop on an assembly line, filtering and regulating the air that drives screwdrivers, grippers and small cylinders.
Fastening tool supply at a maintenance bay
Supplies regulated air to pneumatic wrenches and fastening tools at a maintenance bay, with the automatic drain clearing condensate between jobs.
Wire and cable processing machines
Feeds the air-actuated guides and cutters on a wire processing machine, keeping moisture and debris out of the valve stack.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010ALJF1) the Right Unit?
Pick the J (no-bracket) variant when you mount the unit on existing hardware or a manifold; the same GFR400 body is available with a bracket included. The 3/8 in PT port is the mid-range step, with larger 600 or smaller 300 sizes for other flow needs. The automatic drain suits unattended duty, with manual and differential-pressure drains as alternatives. The 40 um element is standard and the 5 um W option gives finer filtration. The embedded square gauge reads in MPa, with psi or bar scales and an external round gauge orderable. PT is the standard thread, with G (BSPP) and NPT as options. With automatic drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi). Flow is published as curves, not a single rating, so confirm sizing with us 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 (GFR40010ALJF1) FAQ
AirTAC publishes GFR-series flow as performance curves rather than a single rated figure, so there is no single number to quote. Tell us your application and we will confirm sizing against the datasheet curves on request.
The GFR pairs filtration and regulation in one body but does not lubricate. If the downstream equipment needs oil mist, add a GL lubricator after it, or step up to the GFC two-unit or GC three-unit set, which combine the filter-regulator with a lubricator.
