About the AirTAC GC400-10 FRL Unit (GC40010NW)
The GC40010NW is a genuine AirTAC G-series three-unit F.R.L. combination: separate air filter, pressure regulator and lubricator. The W in the code selects the finer 5 um filter element in place of the 40 um standard. This configuration is size 400 with PT 3/8 in ports and a differential-pressure drain on the filter bowl (the series default). No pressure gauge is fitted, as coded by N. With the differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C.
This is a genuine AirTAC part. The G-series F.R.L. combination is offered in 200, 300, 400 and 600 sizes with 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual draining, gauged or non-gauged versions, and PT, G (BSPP) or NPT thread options. On the 400 size the filter and lubricator bowls are polycarbonate (PC). Flow is published as curves rather than a single rated figure, so we confirm sizing and datasheet figures 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.

| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |

| 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. |

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: GF400-10 filter, GR400-10 regulator and GL400-10 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 GC400-10 FRL Unit (GC40010NW) Is Used
Finishing-line spray guns
Feeds air to spray guns on a wood or metal finishing line, where the 5 um element is specified to keep finer particles out of the coating supply while the regulator holds the gun pressure and the lubricator is set per the gun maker.
Laboratory pneumatic bench
Conditions the air on a lab bench running pneumatic test rigs and small actuators, with the finer 5 um grade specified for the instrumentation downstream of the set.
Electronics assembly workstations
Supplies workstations assembling electronic modules, where sensors and small pneumatic components call for the finer filtration grade and a steady regulated pressure at each bench.
Is the AirTAC GC400-10 FRL Unit (GC40010NW) the Right Station?
The key choice in this code is the filter grade: W selects 5 um filtration where the standard element is 40 um, so pick GC40010NW when the downstream equipment needs finer particle removal, and GC40010N where the standard grade is sufficient. Size 400 with 3/8 in PT ports covers mid-to-upper flow duties in the range; verify the step against the curves before ordering.
Drain is the differential-pressure default here, with automatic (A) and manual (M) versions available. The N suffix means no gauge is supplied; gauged versions use an embedded square gauge with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT orderable options. We confirm flow and datasheet figures on request.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC GC400-10 FRL Unit (GC40010NW) FAQ
The series flow data is published as curves rather than a single rated figure, so we do not quote one number. Tell us the inlet pressure, port size and air demand of the machine and we will confirm the correct size and the datasheet figures on request.
Only the filter grade. W selects the 5 um element, while GC40010N carries the 40 um standard. Port, size, drain type, thread and the absence of a gauge are identical between the two codes.
