AirTAC GFR400-15 Filter Regulator (GFR40015AJF1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015AJF1W) 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 (GFR40015AJF1W)
The GFR40015AJF1W is an AirTAC G-series filter regulator: water and particulate removal plus pressure regulation in one 400-size body with a PT 1/2 in port. The W suffix selects the finer 5 um filter element instead of the 40 um standard. This configuration has an automatic drain, an embedded square gauge with MPa scale, and is ordered without a mounting bracket. With automatic drain, the regulation range is 0.15-0.9 MPa (20-130 psi); maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowl on the 400 size is polycarbonate; only the 600 size uses aluminium alloy.
This is a genuine AirTAC part. The G-series filter regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with W), gauge type and scale, thread (PT standard; G and NPT as catalogue options), bracket and check valve. Flow figures are published as curves rather than a single rating, so we confirm the exact flow and datasheet data for your application on request.

Model Code: AirTAC GFR400-15 Filter Regulator (GFR40015AJF1W)
| 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). |
| 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.

- 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 (GFR40015AJF1W) Is Used
Pneumatic air-knife drying station
Feeds the air knives that dry bottles or cans ahead of coding on a packaging line, where the 5 um element helps keep fine particles out of the nozzle passages.
Maintenance-shop air drops
Serves as the regulated supply at maintenance-shop drops powering impact tools and test rigs, with the automatic drain keeping condensate out of a shared workshop supply.
High-speed pick-and-place robot air feed
Conditions air for the valves and vacuum generators on a high-speed pick-and-place robot, where the 5 um grade supports cleaner air to the small, closely toleranced components.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015AJF1W) the Right Unit?
Pick the size series (200/300/400/600) against the port and flow the application needs; here it is the 400 size with a 1/2 in PT port. The W suffix gives 5 um filtration - keep it when finer protection is wanted, or drop W for the 40 um standard element. The automatic drain removes condensate without manual intervention; manual and differential-pressure drains are the other catalogue choices. The embedded square gauge reads in MPa; round external gauges and psi or bar scales can be ordered instead. Thread is PT as standard, with G (BSPP) and NPT available as options, and a mounting bracket can be specified because this code is without one. 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. 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 (GFR40015AJF1W) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so there is no one number to state here. Send us your operating pressures and consumption and we will confirm the flow for this 400-size, 1/2 in model from the datasheet on request.
The W suffix in GFR40015AJF1W selects the 5 um element; the same code without W uses the 40 um standard. Choose 5 um for finer protection of components such as small pilot valves or pneumatic instrumentation, and 40 um for general cylinder and valve supply. Note this unit filters and regulates only - it does not add lubrication to the air.
