AirTAC GFC400-15 Combination Unit (GFC40015ANW)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015ANW) 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 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015ANW)
The AirTAC GFC series is a two-unit F.R.L. set: a filter-regulator plus a lubricator working together, so filtration, pressure regulation and oil-mist lubrication come from one part number. This GFC40015ANW is built in size 400 with PT 1/2 in ports (PT is the standard thread), an automatic drain on the filter bowl, and a 5 um filter element for finer air cleaning. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator covers 0.15-0.9 MPa (20-130 psi) with automatic draining, the PC (polycarbonate) bowls suit -5 to 70 C (non-freezing) service, and an embedded square gauge with MPa scale is included for setting downstream pressure.
This is a genuine AirTAC part in the G series range (sizes 200/300/400/600, ports from 1/8 to 1 inch), with catalogue options including G (BSPP) and NPT threads, manual or differential-pressure drains, 40 um standard or 5 um elements, and round external gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so send us your application and we will 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 0.15 - 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 GFC400-15 Combination Unit (GFC40015ANW)
| 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". |
| A | Drain: Automatic 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. |

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 (GFC40015ANW) Is Used
CNC fixture clamping supply
Feeding filtered, regulated and oil-misted air to power clamps and vises on machining centres, with the 5 um element conditioning air for the clamping valve and the square MPa gauge giving setters a clear pressure reading.
Automated assembly cells
Supplying multi-station pick-and-place and screwdriving modules on an assembly line, where the automatic drain clears condensate from the filter bowl without an operator needing to open it.
Beverage bottling line actuators
Conditioning the air feeding filler-valve and capper-head cylinders on a bottling line, with filtration, regulation and lubrication combined in one compact two-unit set.
Is the AirTAC GFC400-15 Combination Unit (GFC40015ANW) the Right Set?
The size 400 / 1/2 in step sits in the middle of the G series range; if your line demand outgrows a size 300 set, this is the next step up, with 600 available for larger ports. Drain type is a real choice: automatic (this unit) empties condensate without operator attention, manual needs periodic opening, and differential-pressure drains only when pressure drop across the element builds. Filter grade is 40 um standard; the 5 um element here suits circuits with finer control valves. The embedded square MPa gauge is standard on the regulator, with round external gauges in MPa, psi or bar available. PT thread is the standard; order G (BSPP) or NPT where the install requires it.
AirTAC publishes flow for the G series as curves, not a single rated number, so ask us to confirm sizing against your application and line pressure 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 0.15 - 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 GFR400-15 filter regulator on its own.
AirTAC GFC400-15 Combination Unit (GFC40015ANW) FAQ
AirTAC publishes flow for the G series as curves, not a single rated figure, so we do not quote a number on the page. Send us your supply pressure, downstream demand and acceptable pressure drop, and we will confirm the datasheet and sizing figures on request before you order.
The A in this code means the filter bowl has an automatic drain that discharges condensate without operator attention, which suits unmanned or hard-to-reach installations. Manual (M) and differential-pressure (blank) drains are catalogue options on the GFC family; just order the matching suffix.
