AirTAC GFR400-15 Filter Regulator (GFR40015LJF1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015LJF1W) 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 (GFR40015LJF1W)
The AirTAC GFR40015LJF1W is a G-series filter regulator: filtration and regulation in one body, with a drain bowl and no lubricator. The W suffix selects the fine 5 um filter element instead of the 40 um standard. Decoded, it is G400 size with a PT1/2 port (1/2 inch, PT thread as standard), a differential-pressure drain and the L low-pressure regulator type; J omits the mounting bracket, and F fits the embedded square pressure gauge on an MPa scale.
It is a genuine AirTAC part for compressed air only, rated to 1.0 MPa (145 psi) maximum inlet and -5 to 70 C (non-freezing), with a PC (polycarbonate) bowl in the 400 size. The catalogue setting range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi); as an L low-pressure type, confirm its exact adjustment ceiling with us before ordering. The same unit can be ordered with the 40 um element, and the G-series adds 200/300/400/600 sizes, G (BSPP) or NPT threads, automatic or manual drains, round external gauges and brackets. Flow is published as curves, not a single rating, so we confirm flow and datasheet figures 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.
Model Code: AirTAC GFR400-15 Filter Regulator (GFR40015LJF1W)
| 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)). |
| 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. |
| 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. |
| (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.
Size Class
- GFR200PT1/8" - PT1/4"
- GFR300PT1/4" - PT1/2"
- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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 (GFR40015LJF1W) Is Used
Pick-and-place ejectors on an SMT line
Supplying vacuum ejectors and gripper cylinders on a surface-mount pick-and-place module, the 5 um element keeps fine particulate out of the ejector channels, and the embedded gauge lets the line operator verify regulated pressure without opening a panel.
Laboratory instrument air supply
Feeding pneumatically actuated valves inside analytical or laboratory equipment, this filter regulator provides oil-free, finely filtered air at a stable low setting, protecting sensitive internal pneumatics from water and particles.
Air wipe ring on a cable extrusion line
On a wire and cable extrusion line, the unit feeds the air wipe ring that dries the extruded jacket - the 5 um grade keeps nozzles from clogging, and the low-pressure regulator holds a gentle, repeatable wipe pressure.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015LJF1W) the Right Unit?
This code combines the two decisions that matter most for clean-air duties: the W element (5 um instead of the 40 um standard) and the F embedded square gauge on an MPa scale - psi (2) and bar (3) scales are orderable. The G400 frame with a 1/2 inch PT port is the mid step of the 200/300/400/600 series; size the frame and port against the published flow curve, not a single figure, since flow is only given as curves. Drain is the differential-pressure default, with automatic (A) and manual (M) as catalogue alternatives, and J means no bracket is fitted - add one for panel or frame mounting. Thread is PT as the standard, with G (BSPP) and NPT as order options, and the L low-pressure type's adjustment ceiling should be confirmed against your set point 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC GFR400-15 Filter Regulator (GFR40015LJF1W) FAQ
Flow for this unit is published as a curve, not as a single rated figure, so we do not state a number. Give us your inlet pressure, set pressure and air consumption and we will confirm the flow curve from the datasheet and verify the sizing on request before you order.
Yes. PT is the standard thread for this code, and G (BSPP) and NPT versions are catalogue options in the same G400 / 1/2 inch size - they are ordered as alternative suffixes on the model code. Tell us which thread your pipework uses and we will confirm the correct ordering code.
