About the AirTAC GC400-15 FRL Unit (GC40015ANWK)
The GC40015ANWK is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set. This configuration is size 400 with a 1/2 in. PT (standard) port, fitted with 5 um fine filtration, an automatic drain that ejects collected condensate without manual attention, and a reverse (check) valve that helps hold downstream pressure if the supply drops. There is no gauge in this code, so you can fit your own downstream gauge. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this automatic-drain set, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with a choice of port sizes and PT, G (BSPP) or NPT threads. On this size 400 unit the filter bowl is polycarbonate, and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. 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 GC400-15 FRL Unit (GC40015ANWK)
| GC400 | G-series F.R.L. combination, 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. |
| 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. |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-15 filter, GR400-15 regulator and GL400-15 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC400-15 FRL Unit (GC40015ANWK) Is Used
Bottling line conveyor actuators
Filtering, regulating and lubricating the air feeding stopper gates and pusher cylinders on a beverage bottling conveyor, with the automatic drain handling condensate on a line that runs through multiple shifts.
CNC machine pneumatic clamps
Conditioning supply air for the workpiece-clamping circuits of a CNC machining centre, where the 5 um element protects sensitive clamping valves and the check valve holds clamp pressure if the shop supply dips.
Unattended compressor drop legs
Serving a remote corner of a plant air ring main where bowls are rarely visited, so the automatic drain removes water without operator rounds and the set delivers clean, regulated, lubricated air to the branch.
Is the AirTAC GC400-15 FRL Unit (GC40015ANWK) the Right Station?
Choose size 400 with the 1/2 in. PT port when your line sits between the 3/8 in. size 300 step and the 3/4 in. size 600 step; larger sizes carry more flow at a given pressure drop. The automatic drain suits duty where bowls are not checked daily, and the 5 um (W) element gives finer protection than the 40 um standard element. The fitted check valve (K) holds downstream pressure against upstream dips, and the absence of a gauge (N) lets you mount your own.
Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. Because AirTAC publishes flow only as curves, not a single rated figure, ask us to confirm sizing from the datasheet 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
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- 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 the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015ANWK) FAQ
AirTAC publishes flow for the GC400 series as curves rather than a single rated figure, so we do not quote one number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The N in the code means no gauge is fitted, so you can use your own downstream gauge; gauge-equipped versions in the series carry an embedded square gauge or an external round gauge in MPa, psi or bar scales. The A also selects the automatic drain; manual and differential-pressure drain versions of the same set exist if you prefer different condensate handling.
