AirTAC GFC400-15 Combination Unit (GFC40015C1K)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015C1K) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015C1K)
The AirTAC GFC series combines a filter-regulator and a lubricator into one two-unit F.R.L. set for filtration, pressure regulation and oil-mist lubrication of compressed air. This GFC40015C1K is built in size 400 with PT 1/2 in ports (PT is the standard thread), a differential-pressure drain on the filter bowl, the standard 40 um filter element, an external round gauge with MPa scale, and a reverse/check valve fitted as part of the configuration. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator covers 0.15-0.9 MPa (20-130 psi), and the PC (polycarbonate) bowls suit -5 to 70 C (non-freezing) service.
This is a genuine AirTAC part in the G series range (sizes 200/300/400/600, ports from 1/8 to 1 inch), with catalogue options including automatic or manual drains, 5 um elements, square embedded gauges, and G (BSPP) or NPT threads. Flow is published as curves rather than a single rated figure, so share your circuit details and we will 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 0.15 - 0.9 MPa (20 - 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 (GFC40015C1K)
| GFC400 | G-series two-unit set, 400 body — sets the port range. |

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 (GFC40015C1K) Is Used
Pneumatic press setting
Supplying small pneumatic presses and marking heads, where the external round MPa gauge supports repeatable pressure setting and the fitted reverse/check valve matches the specified circuit.
Maintenance workshop benches
Feeding air tools at a maintenance bench, with filter, regulator and lubricator in one set, the MPa gauge for setting, and the differential-pressure drain clearing collected water.
Pneumatic test rig supply
Conditioning supply on pneumatic test benches, where the check-valve configuration and MPa-scaled round gauge suit repeat test setups and lubrication protects the rig's cylinders.
Is the AirTAC GFC400-15 Combination Unit (GFC40015C1K) the Right Set?
Size 400 with 1/2 in ports is the middle step of the G series; move to 600 or down to 300/200 as port and demand require. The K suffix here means a reverse/check valve is fitted; order the non-K code when your circuit does not specify one. The blank drain position gives the differential-pressure type, which clears condensate as pressure drop builds; automatic and manual drains are alternatives. The 40 um element is the standard grade, with 5 um available via the W suffix. C1 specifies the round external gauge on the MPa scale; square embedded gauges and psi/bar scales are also offered. PT thread is standard; G (BSPP) and NPT are order options.
Flow is published as curves rather than 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 0.15 - 0.9 MPa (20 - 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 (GFC40015C1K) FAQ
AirTAC publishes G series flow as curves rather than a single rated figure, so no flow number is stated here. Give us your supply pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet curves and sizing on request before you order.
Only the trailing K: the C1K has a reverse/check valve fitted, while the C1 does not. Size 400, PT 1/2 in ports, differential-pressure drain, 40 um element and the round MPa gauge are identical in both codes.
