AirTAC GFC400-15 Combination Unit (GFC40015ANK)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015ANK) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015ANK)
The AirTAC GFC40015ANK is a two-unit air-treatment set that combines a filter-regulator with a lubricator, so one assembly cleans the air, holds a set downstream pressure and adds oil mist for air-powered tools and cylinders. This 400-size configuration is built around 1/2 in PT ports, carries a 40 um filter element for general-purpose particulate and water removal, and uses an automatic drain that expels collected condensate without anyone opening the bowl. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a reverse/check valve is fitted. No gauge is supplied on this code, so add one separately if a visual pressure readout is needed.
This is a genuine AirTAC part, sold by an authorised distributor at airtacdistr.com. The GFC two-unit line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, an optional 5 um element (code W), gauge and thread variants, and PC bowls on 200-400 sizes (aluminium alloy on 600). Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet numbers for your application.

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 (GFC40015ANK)
| 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. |
| (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. |

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 (GFC40015ANK) Is Used
Automated assembly cell air supply
Feeds a manifold serving air cylinders, grippers and air blow-off nozzles on a robotic assembly line, giving the cell one point where air is filtered, held at a fixed working pressure and lubricated for long cylinder seal life.
Packaging and carton-sealing line
Prepares the air feeding pneumatic pushers, flap-folders and case-closing cylinders on a packaging conveyor, with the automatic drain protecting the line during unattended shifts and the check valve holding the set pressure if upstream supply dips.
Pneumatic press and clamping station
Supplies a workholding clamp or small pneumatic press where the regulator holds a repeatable clamping force and the lubricator keeps the cylinder running smoothly through high-cycle production.
Is the AirTAC GFC400-15 Combination Unit (GFC40015ANK) the Right Set?
Size and port set the flow ceiling: the 400 body with 1/2 in PT ports suits lines running larger cylinders or several tools from one drop, while smaller 200/300 sets cover lighter duty. Choose the drain to match maintenance habits - automatic drain (this code) suits unattended or hard-to-reach installations; manual drain suits stations checked daily; differential-pressure drain is the default. The 40 um element is the standard grade for general plant air; specify 5 um (code W) only where finer pre-filtration is needed.
This code omits the gauge (N), so plan a separate gauge if operators must verify set pressure, and note the fitted reverse/check valve holds downstream pressure if supply dips. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not a single rated figure - ask us to confirm sizing against your air demand 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 (GFC40015ANK) FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your air demand and line conditions and we will confirm the datasheet flow curves for the GFC400 at 1/2 in ports before you order.
The N in GFC40015ANK means no gauge is fitted, and the K means a reverse/check valve is included. The regulator still adjusts across 0.15-0.9 MPa (20-130 psi); if you need a visual readout, order a variant with the gauge code or add a separate gauge. Thread is PT as standard, with G (BSPP) and NPT available as order options.
