AirTAC GFC400-15 Combination Unit (GFC40015MNK)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MNK) 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 (GFC40015MNK)
The AirTAC GFC40015MNK is a two-unit air-treatment set: a filter regulator and a separate lubricator in one 400-size package, providing filtration, regulation and lubrication in one installation. This variant adds the K option - a reverse (check) valve fitted in the regulator section; for full check-valve behaviour and limits, confirm the detail on the datasheet. The set is PT1/2 ported with PT threads as standard, the filter bowl has a manual drain, and the element is the standard 40 um grade. The regulator is the standard type and, with the manual-drain configuration, adjusts over 0.05-0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi). No gauge is fitted.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with optional G (BSPP) and NPT thread variants, automatic or differential-pressure drains, a 5 um (W) element option and gauge choices on regulator-equipped units. The 400-size bowls on the filter and lubricator are PC (polycarbonate). Flow is published as curves rather than a single rated figure, 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 (GFC40015MNK)
| 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. |
| 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: GFR400-15 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 (GFC40015MNK) Is Used
Valve-actuation skid air supply
Use the GFC40015MNK on a skid that strokes automated process valves, so the check-valve option and 40 um filtration protect the positioner and solenoid valves on one regulated, lubricated 1/2 inch line.
Press-shop pneumatic workholding
Fit the set ahead of clamps and swing cylinders on a machining cell's workholding circuit, where the check valve helps the circuit keep its configuration and the manual drain is blown down at shift start.
Trailer and dock-air treatment point
Install the two-unit set at a dock or trailer-testing station fed from the workshop compressor, giving filtered, regulated, lubricated air to test couplings and actuated landing-gear or door rigs.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MNK) the Right Set?
Choose this K variant over the plain GFC40015MN when your circuit needs the reverse (check) valve option fitted at the regulator; otherwise the decode is identical - 400 size, PT1/2 ports, manual drain and 40 um element. Manual drain suits attended plants where bowls are blown down on a routine; pick automatic or differential-pressure drain codes for unattended lines. If you need finer pre-filtration, the 5 um (W) element is the alternative grade. No gauge is included in this code, so consider adding a gauge option when ordering, and switch to the G or T thread suffix if your pipework is BSPP or NPT rather than PT. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 (GFC40015MNK) FAQ
No single rated flow is published for the 400-size G series - AirTAC provides characteristic curves instead. Send us your application pressure and air demand and we will confirm the right size from the datasheet on request before you order.
Only the K option: the MNK has a reverse (check) valve fitted in the regulator section, while the plain MN does not. Everything else decodes the same - 400 size, PT1/2 ports, PT thread, manual drain, 40 um element, standard regulator and no gauge.
