AirTAC GFC400-15 Combination Unit (GFC40015MNW)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MNW) 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 (GFC40015MNW)
The AirTAC GFC40015MNW is a two-unit air-treatment set: a filter regulator and a separate lubricator in one 400-size package, so compressed air is filtered, regulated and lubricated in a single installation. The W in this code specifies the fine 5 um filter element instead of the standard 40 um grade. 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.
Model Code: AirTAC GFC400-15 Combination Unit (GFC40015MNW)
| 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. |

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 (GFC40015MNW) Is Used
Laboratory instrument air feed
Fit the GFC40015MNW on the line supplying lab pneumatic apparatus and bench-mounted testers, where the 5 um element gives finer pre-filtration ahead of regulated, lubricated instrument air.
CNC machine tool air supply
Install the set at the machine-tool air inlet to filter, regulate and lubricate the supply feeding pallet clamps, tool-change cylinders and air blast, with the 5 um element protecting the machine's valves.
Air-knife and nozzle cleaning line
Use the two-unit set upstream of a packaging line's air-knife and nozzle array, so fine-particulate-filtered, regulated, oil-misted air reaches the nozzles through a single 1/2 inch supply.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MNW) the Right Set?
Pick this W variant when the standard 40 um element is too coarse for what your circuit tolerates - the 5 um grade is the finer pre-filtration choice for sensitive downstream equipment. Otherwise the decode is the 400 size with PT1/2 ports, manual drain, standard regulator and no gauge, so add a gauge code at ordering if you want fitted pressure indication. Manual drain assumes an attended installation; choose automatic or differential-pressure drain codes where bowls cannot be blown down routinely. Thread is PT as standard - order the G or T 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
- ✓ 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 (GFC40015MNW) FAQ
AirTAC publishes flow for the 400-size G series as characteristic curves rather than one rated number, so we do not state a single figure. Share your line pressure and air consumption and we will confirm sizing from the datasheet on request.
The W code fits the finer 5 um element in the filter bowl, giving finer particulate removal for circuits with sensitive valves and instruments. Drain type (manual here), port size, regulator range and the rest of the decode stay the same as the standard-grade code.
