AirTAC GFR400-15 Filter Regulator (GFR40015AJC1WK)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015AJC1WK) 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 PT1/2" 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 GFR400-15 Filter Regulator (GFR40015AJC1WK)
GFR40015AJC1WK is an AirTAC GFR400 filter regulator: filtration and regulation in a single body with a 1/2 in PT port. This configuration combines the finer 5 um element (W), an automatic drain, an external round pressure gauge scaled in MPa, a reverse (check) valve (K), and no mounting bracket (J). Maximum inlet pressure is 1.0 MPa (145 psi); with automatic drain, the outlet setting range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. GFR filter regulators are available in sizes 200, 300, 400 and 600, ports from 1/8 to 1 inch, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and PT, G (BSPP) or NPT threads. The 400-size bowl is PC (polycarbonate) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as characteristic curves rather than a single rating, so we confirm 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.

| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". 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 GFR400-15 Filter Regulator (GFR40015AJC1WK) Is Used
Assembly-line torque tool station
Prepares the air at a bench station supplying pneumatic nutrunners and impact drivers on an automotive assembly line, filtered to 5 um and regulated to the tool circuit's set pressure.
Vertical clamp station
Feeds the clamp cylinders on a vertical machining-centre fixture, with the fitted check valve part of the circuit where the downstream set pressure must be preserved through supply dips.
Sorter diverter air prep
Conditions the air driving diverter and pusher cylinders on a distribution-centre conveyor sorter, with automatic draining suited to a line that runs all day.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015AJC1WK) the Right Unit?
This is the fully optioned GFR400: 1/2 in PT port, 5 um filtration, automatic drain, MPa round gauge and check valve, without a bracket. If your duty is lighter, step down to GFR300; for heavier demand, GFR600 is the next step. Consider whether you really need the K check valve and the W fine element - the same body is offered with 40 um filtration and without the check valve. PT thread is standard, G and NPT are catalogue options, and brackets can be ordered separately. AirTAC publishes flow as curves, not one rated number, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GFR400-15 Filter Regulator (GFR40015AJC1WK) FAQ
No single rated flow figure exists for the GFR series; AirTAC publishes flow as characteristic curves against pressure. Send us your line pressure and air demand and we will confirm the GFR400 datasheet curve and the right size step (200/300/400/600) for the application before you order.
GFR units filter and regulate only - there is no lubricator in this body. If your actuators or tools also need oil-mist lubrication, choose the GFC two-unit set (filter regulator plus lubricator) or the GC three-piece F.R.L. combination in the same size. If filtration and regulation alone cover the job, this GFR400 is the simpler choice.
