AirTAC GFR400-15 Filter Regulator (GFR40015ANWK)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015ANWK) 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 (GFR40015ANWK)
The AirTAC GFR400 series filters and regulates compressed air in one body: a drain bowl strips water and particulate, then the regulator sets downstream pressure. This GFR40015ANWK is the size 400 unit with a 1/2 in PT port, an automatic drain, the finer 5 um filter element (code W), and a reverse (check) valve fitted so air cannot flow back through the unit. Regulation spans 0.15-0.9 MPa (20-130 psi) on this automatic-drain version, maximum inlet pressure is 1.0 MPa (145 psi), and no gauge is included.
This is a genuine AirTAC part from the G-series air-treatment range, with a PC (polycarbonate) bowl and a bracket included. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain, element-grade, gauge, thread and check-valve options. Flow is published as curves rather than a single rated figure; we confirm the datasheet and sizing 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. 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 (GFR40015ANWK)
| 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. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 (GFR40015ANWK) Is Used
Optical and electronics assembly benches
Supplies fine-filtered, regulated air to pickup heads, clamps and small actuators at electronics assembly benches, with the 5 um element and check valve protecting the circuit from grit and backflow.
Pharma packaging line diverters
Feeds the diverter and reject cylinders on a pharmaceutical packaging conveyor, where clean regulated air and a fitted check valve support consistent diverting between stops and starts.
Process valve actuation panel
Sits upstream of pneumatically actuated process valves on a skid, filtering and regulating the pilot air supply with the check valve holding the pilot line against reverse flow.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015ANWK) the Right Unit?
Size the unit (200, 300, 400 or 600) to the air demand of your circuit - this size 400 model has a 1/2 in port. Combine the W code for the 5 um element with K for the check valve, as on this model, when the line needs both finer filtration and protection against reverse flow. Drain options are differential-pressure (default), automatic (code A, as here) and manual (code M). Gauges are optional - embedded square or external round, in MPa, psi or bar scales - and thread is PT as standard with G (BSPP) or NPT to order. 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 (GFR40015ANWK) FAQ
We do not state a single rated flow because AirTAC publishes G-series flow as curves, not one figure. Give us your application details and we will confirm the datasheet flow curve and verify the sizing of this size 400, 1/2 in unit with 5 um element and check valve, on request.
No - with no thread letter in the code, the port thread is PT, which is the standard for this series. G (BSPP) and NPT threads are catalogue options you can order by adding G or T to the code; we can quote the variant you need.
