AirTAC GFC400-10 Combination Unit (GFC40010NK)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010NK) 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 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-10 Combination Unit (GFC40010NK)
GFC40010NK 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 a reverse (check) valve fitted as indicated by the K suffix. The filter-regulator section removes water and particulate down to the standard 40 um grade and 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 (40 um standard, 5 um optional), 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 (GFC40010NK)
| 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. |
| (blank) | Filtering grade 40 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, 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 (GFC40010NK) Is Used
Stamping-press part ejectors
Prepares air for the ejector and part-blow-off circuits on a stamping press line, with the check valve helping hold the set downstream pressure in the circuit.
Automated storage and retrieval cells
Conditions air for the gripper and lift actuators in an AS/RS storage cell, filtering, regulating and lubricating on a single 3/8 in supply.
Pneumatic control-valve skids
Feeds pilot air to actuated process valves on a plant skid, keeping the set regulated pressure and a conditioned air supply to the pilot ports.
Is the AirTAC GFC400-10 Combination Unit (GFC40010NK) the Right Set?
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, because AirTAC publishes flow as curves and not as a single rating. The K in this code means a reverse/check valve is fitted, which is the difference from the plain GFC40010N. The 40 um element is standard; the W variant gives 5 um filtration. 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 (GFC40010NK) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not state a number here. Share your supply pressure and demand profile and we will confirm the datasheet and curve figures for this exact set on request before you order.
K indicates that a reverse (check) valve is fitted in this set. The otherwise identical code without K is supplied without the check valve, and gauge, filter grade and drain variants are also orderable in the family.
