The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MNWK) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GFC40015MNWK 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. The W specifies the fine 5 um filter element, and the K adds a reverse (check) valve fitted in the regulator section - confirm the check-valve detail on the datasheet. The set is PT1/2 ported with PT threads as standard, the filter bowl has a manual drain, and the standard-type regulator adjusts over 0.05-0.9 MPa (7-130 psi) in the manual-drain configuration; 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 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.
| 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. |
| W | Filtering grade 5 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.
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.

Fit the GFC40015MNWK on a maintenance shop's test bench supply, combining the 5 um element, check-valve option and lubricator for actuator and valve testing through one 1/2 inch regulated line.
Install the set on the drop feeding a robot's gripper and tool-changer circuit, where fine filtration protects the small control valves and the check-valve option supports the gripper's hold behaviour - details per datasheet.
Use the two-unit set on the control-air header of a parcel sortation module array, giving 5 um filtered, regulated, lubricated air to the diverter actuators from a single treated point.
This is the most specified variant in the list: 400 size, PT1/2 ports, manual drain, the fine 5 um element and the K reverse/check valve option. Choose it when the circuit needs both finer pre-filtration and the check-valve option at the regulator; if 40 um filtration is enough, the GFC40015MNK is the simpler code. Manual drain assumes someone blows the bowl down routinely - otherwise move to an automatic or differential-pressure drain code. No gauge is included, so consider a gauge option at ordering, and use the G or T thread suffix for BSPP or NPT pipework. Flow is published as curves, not a single rating, so ask us to confirm sizing against the application before ordering.
Quick checklist
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.
Flow for the 400-size G series is published as characteristic curves, not as a single rated figure, so we avoid quoting one number. Give us your working pressure and air demand and we will confirm the sizing against the datasheet on request before you order.
GFC is the two-unit filter regulator plus lubricator set, 400 is the size, 15 is the 1/2 inch port, M is the manual drain, N means no gauge, W is the 5 um filter element and K is the reverse/check valve option fitted in the regulator section.
