About the AirTAC GC400-15 FRL Unit (GC40015NW)
GC40015NW is an AirTAC G-series three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built in the GC400 size with PT 1/2 in ports. In this configuration the filter carries the finer 5 um element (W), the filter bowl uses a differential-pressure drain, the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the N in the code means no pressure gauge is fitted. The filter and lubricator bowls are polycarbonate in the 400 size. Medium is compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series comes in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of PT (standard), G (BSPP) or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um filtration, and gauge options. Flow figures are published as curves rather than a single rated number; ask us and we will confirm the datasheet figures for your application.

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 (GC40015NW)
| 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". |
| (blank) | Drain: Differential-pressure 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. |
| (blank) | No reverse-flow valve (the default). |
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 (GC40015NW) Is Used
Assembly-line cylinder supply
Filtering, regulating and lubricating the compressed air feeding clamp and eject cylinders on a manual assembly station, with the 5 um element helping protect tight-clearance valve internals.
CNC tool-change circuit
Conditioning the air to the tool-changer and pallet-clamp circuits of a CNC machining center, where the regulator sets a stable line pressure and the lubricator mists the air-motor components.
Packaging line diverters
Supplying treated air to the pusher and diverter cylinders on a bottling or carton conveyor, with the 1/2 in ports matching the main drops along the line.
Is the AirTAC GC400-15 FRL Unit (GC40015NW) the Right Station?
The GC range steps through 200, 300, 400 and 600 sizes; this 400 size carries 1/2 in PT ports, so move up or down a size if your plumbing or air demand sits at a different port step. The W code fits the 5 um element instead of the standard 40 um. The differential-pressure drain (blank position) needs no daily attention; specify A (automatic) or M (manual) in the code if you prefer a different drain. The N position means this unit is ordered without a gauge - a square or round gauge in MPa, psi or bar scales can be chosen via the gauge code instead. The thread letter at the end selects blank = PT (standard), G = G (BSPP) or T = NPT.
Published flow data for this series is given as curves, not a single rating, so send us your application details 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
- ✓ 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 (GC40015NW) FAQ
AirTAC publishes G-series capacity as flow curves rather than a single rated figure, so we do not quote one number here. Tell us your operating pressure and air demand and we will confirm the datasheet curve for this GC400 1/2 in size on request.
N means no pressure gauge is fitted on the regulator. G-series combinations can be ordered with an embedded square gauge or an external round gauge, in MPa, psi or bar scales, by choosing the matching gauge code when you order.
