AirTAC GFC400-10 Combination Unit (GFC40010NW)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010NW) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT3/8" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-10 Combination Unit (GFC40010NW)
GFC40010NW is a genuine AirTAC GFC two-unit air preparation set: a filter regulator and a lubricator supplied as a matched pair for one 3/8 in PT ported line, with the W suffix specifying the finer 5 um filter element instead of the standard 40 um grade. The filter-regulator section holds downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment window that applies with the differential-pressure drain fitted. The N suffix means no gauge is included. Size 400 handles compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi), a working range of -5 to 70 C (non-freezing), and a polycarbonate bowl on the filter-regulator section.
This is a genuine AirTAC part in the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and thread options PT, G (BSPP) and NPT. Filter grade, drain type, gauge and reverse-check valve are all orderable variants. AirTAC publishes flow as curves rather than a single rated figure, so we confirm the datasheet and flow data 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 set has no separate bracket code — the two 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 GFC400-10 Combination Unit (GFC40010NW)
| GFC400 | G-series two-unit set, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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 set. Constituent units, orderable separately as spares: GFR400-10 filter regulator and GL400-10 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC400-10 Combination Unit (GFC40010NW) Is Used
Pneumatic measuring fixtures
Supplies cleaner 5 um-filtered, regulated and lubricated air to the actuated clamps and ejection cylinders of in-process measuring fixtures on a production line.
Bench-scale process rigs
Conditions air for valve and cylinder actuation on laboratory and pilot-plant process rigs, where the finer 5 um element supports a cleaner supply at the bench.
Electronics assembly workstations
Feeds air-driven screwdrivers and clamp fixtures at electronics assembly workstations from a single regulated, lubricated 3/8 in drop.
Is the AirTAC GFC400-10 Combination Unit (GFC40010NW) the Right Set?
The W in this code selects the 5 um filter element; pick the standard 40 um grade (same set without W) when only coarse water and particle removal is needed. Size 400 with a 3/8 in PT port sits mid-range in the G series; confirm your flow requirement with us before stepping between sizes, since AirTAC publishes flow as curves and not as a single rating. No gauge is fitted on this code, and gauge variants with different scales exist in the family. PT is the standard thread, with G (BSPP) and NPT as catalogue thread options. Ask us to confirm sizing and the datasheet against your application before ordering.
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
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR400-10 filter regulator on its own.
AirTAC GFC400-10 Combination Unit (GFC40010NW) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so no single number is quoted here. Tell us your supply pressure and air demand and we will confirm the datasheet and curve data for this exact set on request before you order.
W selects the 5 um filter element in the filter-regulator section instead of the standard 40 um grade. Drain type, gauge, thread and reverse-check valve are separate orderable choices in the same family.
