AirTAC GFC400-15 Combination Unit (GFC40015AN)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015AN) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015AN)
The AirTAC GFC series is a two-unit air-treatment set: a filter-regulator paired with a lubricator, so one assembly removes water and particulate, holds a set downstream pressure and meters oil mist into the air line. This unit is size 400 with a PT1/2 port (PT thread is the standard; G and NPT are catalogue options), an automatic drain on the filter bowl so condensate is discharged without operator attention, the standard 40 um filter element, and no gauge fitted (code N). It is the standard regulator type: with the automatic drain, outlet pressure adjusts over 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing); the size 400 filter bowl is PC (polycarbonate). Across the G series you can step size and port from 200 to 600, choose differential-pressure, automatic or manual drains, order the 5 um (W) element instead of 40 um, add gauge and bracket options and select PT, G (BSPP) or NPT threads. Flow for this size is published as curves rather than a single rated figure, so we confirm datasheet and sizing values 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: GFR400-15 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 (GFC40015AN) Is Used
CNC machining centre pneumatics
Conditioning plant air for tool-change cylinders, chip augers and air blasts on a vertical machining centre; the 1/2" PT port matches the machine's main air drop and the automatic drain handles condensate.
Bottling line stopper cylinders
Running stopper and gate cylinders on a bottling conveyor; the filter-regulator section keeps the pressure steady over 0.15-0.9 MPa (20-130 psi) while the lubricator mists oil to the cylinder seals.
Bench pneumatic press
Supplying a bench-mounted pneumatic press in an electronics assembly cell; the 40 um element guards the control valve and the regulator holds the operator's set pressure through each pressing cycle.
Is the AirTAC GFC400-15 Combination Unit (GFC40015AN) the Right Set?
Real choices in this family: step the size and port (200/300/400/600; here 400 with a PT1/2 port) against the flow your line needs; pick the drain - automatic on this unit, with differential-pressure (default) and manual also available; choose the 40 um standard element or the 5 um (W) option; select thread PT as the standard with G (BSPP) and NPT orderable; and specify a gauge if you want a visual pressure readout, since none is fitted here (MPa, psi or bar scales are orderable). 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 0.15 - 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 (GFC40015AN) FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number here. Share your line pressure, set pressure and demand and we will confirm the sizing from the datasheet on request.
The N in GFC40015AN means no gauge is fitted. Units with a regulator can take an embedded square gauge or an optional external round gauge, with MPa, psi or bar scales orderable - tell us the scale you want and we will confirm the option on request.
