AirTAC GFC400-15 Combination Unit (GFC40015MLNW)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MLNW) 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).

About the AirTAC GFC400-15 Combination Unit (GFC40015MLNW)
GFC40015MLNW is an AirTAC G-series two-unit air preparation set: a filter regulator plus a separate lubricator as one 2-piece combination. The filter-regulator section removes water and particulate from compressed air and holds downstream pressure steady, while the lubricator meters an oil mist to downstream tools and cylinders. The W suffix selects the finer 5 um filter element; the rest decodes to a 400-size unit with 1/2 in PT ports, a manual drain, and the low-pressure regulator type, with no gauge fitted (N).
It is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with port choices and G (BSPP) or NPT thread options to order. The polycarbonate (PC) bowls on both sections suit compressed air from -5 to 70 C, and the manual drain allows regulator adjustment from 0.05 to 0.9 MPa (7-130 psi). Rated flow is published as curves rather than a single figure, so ask us and we will 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GFC40015MLNW)
| 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)). |
| L | Low-pressure 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. |
| (blank) | No reverse-flow valve (the default). |
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 (GFC40015MLNW) Is Used
Control panel instrument air feed
Conditioning the air feeding pilot regulators and I/P positioner circuits on a control panel skid, where the 5 um element protects fine orifice components and the panel carries its own gauge.
Fixture clamping on weld cells
Supplying regulated, lubricated air to the swing clamps and hold-down cylinders of a robotic weld cell, with the manual drain cleared at the start of each maintenance window.
Air knife and blow-off stations
Preparing the supply to blow-off and air knife nozzles on a parts-cleaning station, filtering carryover from the header and holding a steady regulator setting for consistent sheet cleaning.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MLNW) the Right Set?
This 400-size 1/2 in set combines the 5 um W-grade element (the finer option; standard is 40 um) with a gaugeless N configuration for panels that read pressure elsewhere. The M drain is manual: condensate is vented by hand, and manual-drain units allow the widest regulator setting range, 0.05-0.9 MPa (7-130 psi). Gauge variants and G/NPT threads are order options, as are the other size/port steps. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 (GFC40015MLNW) FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated number, so we do not state one. Tell us your application conditions and we will confirm the datasheet curves for this 400-size, 1/2 in PT set on request.
The GFC two-piece set pairs the filter regulator with the lubricator, covering filter, regulation and lubrication in two units instead of three. It is the right choice when you want those three functions with fewer components; the GC adds a separate filter and regulator as individual bodies if your layout prefers that.
