Airtac GFC Combination Unit GFC300C10AC1K
The AirTAC GFC Combination Unit GFC300C10AC1K 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 GFC300C10AC1K
The AirTAC GFC series is a two-piece air preparation set: a filter regulator plus a lubricator ordered as one unit. This 300-size, PT3/8 configuration 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 automatic drain expels collected condensate without operator attention, the external round gauge reads set pressure on the MPa scale, and the K suffix means a reverse (check) valve is fitted to hold downstream pressure through upstream supply dips.
This is a genuine AirTAC part. The G series is available in sizes 200 to 600 with PT as the standard thread and G(BSPP) or NPT as catalogue options; an embedded square gauge and psi or bar scales are alternative orderable choices. 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 GFC300C10AC1K Is Used
Machining centre fixture clamps
A PT3/8 supply set for the air-actuated clamps on a machining-centre fixture: the check valve keeps clamp pressure if the shop supply dips, the automatic drain handles condensate on an unattended cell, and the MPa gauge gives the setter a clear pressure reading.
Palletiser gripper header
Conditioning air on a palletiser's gripper header, where the reverse valve holds the gripper circuit through supply dips and filtered, regulated, lubricated air keeps the gripper cylinders and vacuum ejectors working reliably.
Press line die-change table
Feeding the die-change table's air bearings and lock cylinders on a stamping press line, with the automatic drain coping with heavy condensate loads and the check valve preserving the lock-circuit pressure between moves.
Is the Airtac GFC Combination Unit GFC300C10AC1K the Right Set?
This code is the GFC300C10AC1 with a fitted reverse (check) valve - specify it wherever clamps, gates or holding circuits must keep their regulated pressure if shop air is lost. The rest decodes the same: size 300 with a 3/8 in PT port for heavier station drops, 40 um standard filtration (5 um W grade as the alternative), automatic drainage (manual and differential-pressure are orderable), and an external round gauge in MPa with psi or bar as options. G(BSPP) and NPT threads are orderable alternatives.
Flow is published as curves, not a single rating, so send your flow and pressure points and we will confirm sizing against the datasheet before you order.
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 GFC300C10AC1K FAQ
Flow for the AirTAC G series is published as performance curves rather than a single rated number, so we do not state one here. Share your application's flow and pressure points and we will confirm sizing against the datasheet on request.
The fitted reverse (check) valve holds downstream regulated pressure if the upstream supply is interrupted - important for clamps, grippers and holding circuits. Otherwise this is a two-unit set: a 40 um filter regulator with automatic drain and an external round MPa gauge, plus a lubricator, in 3/8 in PT ports.
