AirTAC GFR400-15 Filter Regulator (GFR40015JF1WK)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015JF1WK) 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 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 GFR400-15 Filter Regulator (GFR40015JF1WK)
The GFR40015JF1WK combines two options on the AirTAC GFR filter regulator: the W 5 um filter element and the K reverse (check) valve fitted in the unit. One body removes water and particulate from compressed air and holds downstream pressure at a set point. This 400-size unit has a PT1/2 port, the default differential-pressure drain and the built-in square gauge scaled in MPa. Regulation range is 0.15 to 0.9 MPa (20-130 psi) and maximum inlet pressure is 1.0 MPa (145 psi).
It is a genuine AirTAC part, rated -5 to 70 C (non-freezing), with a polycarbonate bowl at the 400 size. The same body is available with the standard 40 um element, without the check valve, with automatic or manual drains, and with other gauge scales and threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and correct size for your circuit.

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 GFR400-15 Filter Regulator (GFR40015JF1WK)
| 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". |
| (blank) | Drain: Differential-pressure 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). |
| F | Gauge shape: Square. 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. |

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 (GFR40015JF1WK) Is Used
Pick-and-place gripper air
Conditions and regulates the supply to the grippers on a robotic pick-and-place cell, with the 5 um element and the check valve both fitted in the same body at the cell's air drop.
Test fixture actuation
Feeds the pneumatic clamps of an electronics test fixture, where the specification calls for the 5 um element on the actuation supply at the pressure the fixture was designed around.
Diverter gate actuators
Supplies the diverter and gate actuators on a sorting conveyor line, with filtered, regulated air and the reverse valve fitted at the regulator rather than plumbed separately.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015JF1WK) the Right Unit?
This code stacks the two most common options: the 5 um element (W) for finer filtration and the built-in check valve (K) so no separate inline part is needed. The 400 size with a PT1/2 port is the step above the 300 for higher-demand lines. Drain is the default differential-pressure type, with automatic (A) and manual (M) codes available on the same body. Gauge scale can be MPa, psi or bar at order time, thread can be G (BSPP) or NPT instead of the PT standard, and the J suffix means no mounting bracket is included. 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 (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 (GFR40015JF1WK) FAQ
Flow for the G series is published as curves, not as a single rated number, so there is no one figure to quote. Give us your inlet pressure and demand and we will confirm the datasheet and flow curve for the GFR400 so you can check it against the application before ordering.
Yes - that is exactly what the WK suffix means: the W 5 um filter element plus the K reverse (check) valve on the same GFR400-15 body. If you need only one of the two options, order the plain JF1 code for 40 um without check valve, JF1W for 5 um only, or JF1K for the check valve only.
