AirTAC GFC400-15 Combination Unit (GFC40015AF1W)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015AF1W) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015AF1W)
The AirTAC GFC40015AF1W is a two-unit air-treatment set that combines a filter regulator with a lubricator: it removes water and particulate, holds a set downstream pressure, and adds oil mist for air tools and cylinders. This configuration is the 400 size with PT1/2 ports, an automatic drain on the filter-regulator bowl, a 5 um filter element, and an embedded square gauge scaled in MPa. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) with the automatic drain, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series, which spans sizes 200, 300, 400 and 600 with optional G (BSPP) and NPT thread variants, manual or differential-pressure drains, 40 um or 5 um elements, and gauge choices. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet and sizing for your application 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 (GFC40015AF1W) Is Used
CNC machining cell air supply
Feeding the tool-changer and clamping circuits on a CNC machining centre: clean, regulated 1/2-inch air with lubrication for the actuator cylinders, and a 5 um element ahead of the finer valve islands.
Automated paint-line spray guns
Supplying spray guns on an automated coating line, where the 5 um grade helps keep water and particles out of the finish and the lubricator mists oil to the gun trigger air motor.
Palletiser valve-terminal supply
Conditioning air at the drop of a palletiser's valve terminal bank: the regulator holds stable pressure to the directional valves while the automatic drain clears condensate from the bowl.
Is the AirTAC GFC400-15 Combination Unit (GFC40015AF1W) the Right Set?
Step up from 300 to 400 size when your line's port standard is 1/2 inch and flow demand sits above what the smaller bodies serve; check the curve rather than guessing. This unit has the automatic drain, so condensate is expelled without operator attention - choose manual only where someone checks the point daily. The 5 um element suits downstream equipment that wants finer filtration than the standard 40 um; the square MPa gauge matches panels specified in metric units. PT is the standard thread; G (BSPP) and NPT are catalogue options to order.
Flow is published as curves, not a single rating, so send us your flow and pressure conditions and we will confirm sizing against the datasheet before you order.
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 (GFC40015AF1W) FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
The W in the code specifies the optional 5 um filter grade. It is chosen where downstream valves, cylinders or processes are sensitive to finer particles; the standard element in this family is 40 um. Both grades are catalogue options across the G-series filter sets.
