AirTAC GFR400-15 Filter Regulator (GFR40015MLJC1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015MLJC1W) 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 (GFR40015MLJC1W)
The AirTAC GFR40015MLJC1W is a filter regulator with the finer 5 um filter element specified by the W suffix. It filters water and particulate from compressed air and regulates downstream pressure in one body, configured here with a PT1/2 port, manual drain, low-pressure (L) regulator type, external round pressure gauge scaled in MPa, and no mounting bracket (J). The 400-size bowl is polycarbonate.
This is a genuine AirTAC part in the G series 200-600 size range. The same body is available with the 40 um element, automatic or differential-pressure drains, a bracket, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than one rated figure, so we confirm the datasheet number 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.
Model Code: AirTAC GFR400-15 Filter Regulator (GFR40015MLJC1W)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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 (GFR40015MLJC1W) Is Used
Pilot air for large control valves and actuators
Positioners and pilot circuits on large process valves need finely filtered air at a stable low pressure. This unit conditions the PT1/2 supply line, with the 5 um element protecting the positioner's fine internals.
Environmental chamber and test-cell instrumentation
Instrument air to sensors and purge fittings in test cells must be free of fine particles and held well below line pressure. The round MPa gauge lets the technician verify setpoint without opening the panel, and the bowl is drained by hand between runs.
Air curtains and sealing air on food packaging lines
Sealing-air and guard-air circuits on packaging machinery depend on clean, low-pressure air. The 5 um element guards the small orifices in these circuits while the low-pressure type trims the supply to the level the circuit was designed for.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015MLJC1W) the Right Unit?
This code gathers four real choices in one model: the 5 um element for applications that cannot tolerate coarse particulate, the manual drain where hands-on drainage fits the maintenance routine, the round external MPa gauge for readable setpoints on a machine frame, and no bracket where the unit is plumbed in-line rather than wall-mounted. At 400 size and PT1/2, it is the step above the 3/8 in 300-series body; step up or down only if the flow curves say so. Thread is PT as standard with G and NPT as order options.
Because AirTAC states flow only as performance curves, not a single rating, send us your required flow and pressure and we will confirm sizing from the datasheet before you order.
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 0.05 - 0.9 MPa (7 - 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 (GFR40015MLJC1W) FAQ
No. AirTAC publishes filter-regulator flow only as performance curves, so there is no single rated figure. Send us your line pressure and air demand and we will confirm the correct size from the datasheet before you place the order.
Both are 400-size, PT1/2, low-pressure type filter regulators with manual drain and 5 um elements. This JC1W version has no mounting bracket and an external round MPa gauge, while the F1W includes the bracket and uses the embedded square MPa gauge instead.
