Airtac GFC Combination Unit GFC300C10AC1
The AirTAC GFC Combination Unit GFC300C10AC1 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 GFC300C10AC1
The AirTAC GFC series is a two-piece air preparation set: a filter regulator plus a lubricator ordered as one unit. This 300-size configuration is threaded PT3/8 and filters to the standard 40 um grade, regulates working pressure across 0.15-0.9 MPa (20-130 psi), and lubricates downstream components with an oil mist. The A in the code specifies an automatic drain, which expels collected condensate from the bowl without operator attention, and an external round gauge on the MPa scale is included so operators can read set pressure directly.
This is a genuine AirTAC part. The G series spans sizes 200 to 600, with PT as the standard thread and G(BSPP) or NPT as catalogue options; the regulator can alternatively carry an embedded square gauge, and gauge scales come in MPa, psi or bar. Flow is published as curves rather than a single rated figure, 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 0.15 - 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: GFR300-C1 filter regulator and GL300-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 GFC300C10AC1 Is Used
CNC machine tool air supply
Conditioning shop air feeding a CNC machining centre's tool-change cylinder and air-blast circuits: the automatic drain copes with condensate from humid shop air, and the MPa gauge lets maintenance read the set pressure at a glance.
Fleet workshop service drops
A PT3/8 drop at a truck and bus service bay feeding impact wrenches and tyre-cage inflating circuits, with the lubricator oiling the tool motors and the regulator holding a steady working pressure.
Case-erector carton feed section
Supplying the vacuum generators and flap-folding cylinders on a case-erector's carton feed section, where the automatic drain keeps the bowl clear during long unattended runs.
Is the Airtac GFC Combination Unit GFC300C10AC1 the Right Set?
Key decode choices here: the 3/8 in PT port steps up from 1/4 in for circuits that move more air through the same size-300 body - and because published flow is a curve, step up a size only after checking demand. The automatic drain suits unattended or hard-to-reach mounting; choose manual (M) where you want purge control at shutdown, or the differential-pressure default where cost matters most. This set carries the 40 um standard element (the 5 um W grade is the alternative) and an external round gauge in MPa - psi and bar scales are orderable, as are G(BSPP) and NPT threads.

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 GFR300-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C10AC1 FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a number here. Give us your peak flow and working pressure and we will confirm the size-300, PT3/8 selection against the datasheet on request.
The A in this code specifies an automatic drain, which discharges collected condensate on its own and suits unattended positions or bowls mounted where nobody walks past. The differential-pressure drain is the default and costs-conscious choice; manual (M) gives you deliberate purge control. All three are orderable on the GFC family.
