AirTAC GFC400-15 Combination Unit (GFC40015MC1K)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MC1K) 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 PT1/2" ports, a 40 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015MC1K)
The AirTAC GFC40015MC1K is a two-unit compressed-air treatment set: a filter regulator plus a separate lubricator, so the air is filtered, regulated and then oiled in one mounting group. This 400-size configuration carries a 1/2 in PT port, a manual drain on the bowl, the standard 40 um filter element, an external round pressure gauge reading in MPa, and a reverse (check) valve fitted to hold downstream pressure. With the manual drain, the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part in the G series 200/300/400/600 range, with choices of port size, G (BSPP) or NPT thread options, drain type, 5 um or 40 um filtration and gauge scale. Rated inlet pressure is 1.0 MPa (145 psi) 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 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 0.05 - 0.9 MPa (7 - 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 GFC400-15 Combination Unit (GFC40015MC1K)
| GFC400 | G-series two-unit set, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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 set. Constituent units, orderable separately as spares: GFR400-15 filter regulator and GL400-15 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 GFC400-15 Combination Unit (GFC40015MC1K) Is Used
CNC machining cell air prep
Filtered, regulated and lubricated air supplied to a CNC machining centre's pneumatic clamping, tool-change and chip-ejection circuits, with the check valve holding settings during supply dips.
Packaging line cylinder supply
Air preparation ahead of the pick-and-place and carton-forming cylinders on a packaging conveyor, where the lubricator keeps seals conditioned through continuous shifts.
Pneumatic press station
A workshop air press or riveting station fed at a set pressure, with the 1/2 in PT port matching the main drop and the MPa gauge giving the operator a clear local reading.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MC1K) the Right Set?
For a 1/2 in line, the 400 size is the natural step; drop to GFC300-10 if your flow demand is modest, or step up to 600 for large headers. The manual drain here suits points of use that are checked by an operator; choose automatic drain if the set is mounted where nobody opens the bowl. The 40 um element protects cylinders and valves; specify the W variant for a 5 um element. Gauge C1 is the external round gauge in MPa (C3 reads bar, C2 psi). Thread is PT as standard, with G (BSPP) and NPT as orderable options; a bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing 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
- ✓ 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 0.05 - 0.9 MPa (7 - 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 GFR400-15 filter regulator on its own.
AirTAC GFC400-15 Combination Unit (GFC40015MC1K) FAQ
AirTAC publishes flow for the G series as characteristic curves, not as a single rated number, so there is no one figure we can honestly quote here. Ask us and we will confirm the flow and datasheet figures for the 400 size against your application before you order.
The M in the code selects a manual drain, so condensate is emptied by opening the bowl rather than automatically, which suits attended installations. The trailing K fits a reverse (check) valve, which keeps the regulated downstream pressure from bleeding back if the supply line drops.
