Airtac GFC Combination Unit GFC400C15AN
The AirTAC Airtac GFC Combination Unit GFC400C15AN 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC400C15AN
The AirTAC GFC400C15AN is a two-unit air preparation set from the G series: a filter-regulator and a separate lubricator, size 400, piped PT1/2 (1/2 inch), for compressed air only. In service the filter-regulator bowl removes water and particulate through the standard 40 um element, the regulator holds your set downstream pressure (0.15 to 0.9 MPa / 20-130 psi adjustment on this automatic-drain version), and the lubricator meters an oil mist into the clean air for downstream cylinders and tools. The bowl drains automatically, no pressure gauge is fitted (code N), and maximum working pressure is 1.0 MPa (145 psi) over a -5 to 70 C, non-freezing range. Bowls in the 400 size are polycarbonate.
This is a genuine AirTAC part, one configuration of a family that runs from size 200 to size 600 with ports from 1/8 to 1 inch. Catalogue options include the 5 um W element, manual or differential-pressure drains, embedded square or external round gauges in MPa, psi or bar scales, reverse (check) valve versions, a low-pressure type, and G (BSPP) or NPT threads in place of the PT standard. AirTAC publishes flow as curves rather than a single rating, so ask us and we will confirm the datasheet and figures for this exact model 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.

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-C1 filter regulator and GL400-C1 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 GFC Combination Unit GFC400C15AN Is Used
Robotic palletizer gripper circuit
Filtered, regulated and lubricated air for the gripper cylinders and vacuum generator on a palletizing robot's end-of-arm tooling, fed from a 1/2 inch drop with the setpoint set once at the cell.
Bottling line diverters
Supplies the stopper and diverter cylinders along a bottling hall conveyor; the automatic drain clears condensate at an unattended drop without a daily manual drain routine.
Case erector valve stack
Prepares air for the solenoid valve stack driving the clamp and flap-fold cylinders of a corrugated case erector, with the 40 um element protecting the valve seats.
Is the Airtac GFC Combination Unit GFC400C15AN the Right Set?
Match the 400 size and its 1/2 inch PT ports to the flow your line actually needs: stepping to size 300 or 600 changes the port and the capacity, and because AirTAC publishes flow as curves rather than one rated number, send us your application and we will confirm sizing before you order. Then set the remaining decodable choices: drain type (automatic here, with manual and differential-pressure as catalogue alternatives), element grade (40 um standard here, 5 um with the W code), gauge (none fitted on this N version; embedded square or external round gauges in MPa, psi or bar scales are options), and thread (PT standard, with G and NPT as orderable specifications). Low-pressure type and reverse-valve versions also exist in this family.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC400C15AN FAQ
AirTAC publishes G series flow as performance curves rather than a single rated figure, so no rated flow number is quoted here. Send us your line pressure and air demand and we will confirm the flow data and full datasheet for this exact model on request.
N means this set is supplied without a gauge. G series units with a regulator accept an embedded square gauge, and an external round gauge is optional, in MPa, psi or bar scales; order the catalogue code with the gauge option you want.
