AirTAC GFC400-15 Combination Unit (GFC40015MC1WK)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MC1WK) 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 (GFC40015MC1WK)
The AirTAC GFC40015MC1WK is a two-unit compressed-air treatment set: a filter regulator plus a separate lubricator, filtering, regulating and lubricating the supply in one group. This 400-size configuration has a 1/2 in PT port, a manual drain, the fine 5 um (W) filter element, an external round gauge reading in MPa and a reverse (check) valve fitted. With the manual drain, the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
It is a genuine AirTAC part in the G series 200/300/400/600 size range, with order options covering port size, G (BSPP) or NPT threads, drain type, filtration grade and gauge scale. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than one rating, so we confirm 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 (GFC40015MC1WK)
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.
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 (GFC40015MC1WK) Is Used
Robotic weld cell services
Filtered, regulated and lubricated air for the grippers and clamps on a robotic welding cell, with the check valve holding actuator pressure while the line pressure settles.
Food plant packaging auxiliaries
Air preparation for case packers and labelers on a packaging floor, where the 5 um element supports cleaner air to the positioner and valve circuits.
Maintenance shop air drops
A serviced air drop in a plant maintenance shop feeding impact tools and test fittings, with regulated pressure, oil mist and a local MPa gauge at the point of use.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MC1WK) the Right Set?
Choose this code when you need three things at once on a 1/2 in line: the finer 5 um element (W), the check valve (K) to hold downstream pressure through supply dips, and the round MPa gauge (C1). If your pressure instruments read in bar or psi, the C3 or C2 gauge variants decode the same otherwise. Manual drain suits attended points of use; pick the automatic-drain variant for unattended duty. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and a bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your 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 (GFC40015MC1WK) FAQ
No - AirTAC publishes flow for this series as characteristic curves, not as one rated number, so quoting a single figure would not be honest. Send us your line pressure and demand and we will confirm the datasheet flow curves for the 400 size before you order.
K fits a reverse (check) valve in the set, so regulated downstream pressure is held if the upstream supply dips or is shut off. Combined with the W for the 5 um element, this code is the fine-filtration, check-valved version of the GFC40015 two-unit set with a manual drain and MPa gauge.
