AirTAC GFR400-15 Filter Regulator (GFR40015LJC1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015LJC1W) 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 (GFR40015LJC1W)
The AirTAC GFR40015LJC1W is a G-series filter regulator: filtration and pressure regulation in one body, with a drain bowl but no lubricator. The W suffix selects the 5 um filter element instead of the 40 um standard, for cleaner downstream air. This unit 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 means no mounting bracket, and C fits the external round 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. With the differential-pressure drain the catalogue setting range 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 configuration exists with a 40 um element, and the G-series offers 200/300/400/600 sizes, G or NPT threads, automatic or manual drains and optional 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 (GFR40015LJC1W)
| 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). |
| 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. |
| (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

- 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 (GFR40015LJC1W) Is Used
Automotive paint line spray guns
At the drop feeding spray guns on an automotive refinish or paint line, the 5 um element strips finer particulate than the standard grade, and the absence of a lubricator keeps oil mist off the coated surface.
Valve positioners on a process skid
Supplying pneumatic valve positioners and transmitters on a chemical or water-treatment skid, this filter regulator delivers filtered, steady low-pressure air so control devices see a clean, stable signal supply.
Blow-off nozzles on an electronics line
Feeding blow-off nozzles that clear swarf and dust from PCB assemblies, the unit filters the shop air to 5 um and holds a gentle, repeatable regulated pressure so components are not disturbed.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015LJC1W) the Right Unit?
Choose this code over the plain GFR40015LJC1 when the 5 um element matters - it is the right call where finer particulate must be kept out of valves, instruments or a finished surface; the standard 40 um grade suits general actuator supply. The G400 / 1/2 inch port step sits mid-range in the 200/300/400/600 series - size it against the flow curve, not a headline number, since flow is published as curves only. Drain is the differential-pressure default; automatic (A) or manual (M) drains are catalogue alternatives. Gauge is the external round type on an MPa scale; the square embedded gauge (F) is an option. Thread is PT as standard, with G (BSPP) and NPT orderable, and J means no bracket is fitted - add one if the unit will be wall or machine mounted.
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 (GFR40015LJC1W) FAQ
AirTAC gives G-series flow as performance curves rather than one rated figure, so there is no single number we can quote. Share your operating pressure and demand and we will pull the flow curve from the datasheet and confirm sizing on request before you order.
The standard 40 um grade suits general cylinder and valve supply; the W suffix selects a 5 um element for finer filtration - paint and coating work, instrumentation, sensors and other duties where finer particulate causes problems. The rest of the code is unchanged, and either grade can be ordered in the same body.
