Airtac GFC Combination Unit GFC300C08AF1WK
The AirTAC GFC Combination Unit GFC300C08AF1WK 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 GFC300C08AF1WK
The AirTAC GFC two-unit set combines a filter regulator and a lubricator, giving filtered, regulated and oil-mist-lubricated air from one 1/4 in PT connection. This version is fitted with a reverse (check) valve so flow through the set cannot run backwards, and it carries the fine 5 um element, an automatic drain, a standard-type regulator and an embedded square gauge scaled in MPa.
This is a genuine AirTAC part. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and at size 300 the bowls are polycarbonate. The family spans sizes 200 to 600 with alternative drains, thread options and a no-check-valve variant; we confirm flow and datasheet 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-C0 filter regulator and GL300-C0 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 GFC300C08AF1WK Is Used
Fixture clamping on a CNC cell
Feeds the swing clamps on a machining fixture; the fitted check valve blocks reverse flow through the set, the regulator holds the clamp circuit pressure, and the lubricator conditions the clamp's air side.
Bench-top pneumatic test rigs
Conditions supply air for a laboratory leak-test or pressure-test bench: the 5 um element keeps the test circuit clean ahead of the regulator, and the square MPa gauge gives a direct pressure readout.
Pneumatic valve actuation skid
Regulates and lubricates the air supply to quarter-turn actuators on a small valve skid; the check valve prevents backflow through the set when an upstream branch is isolated.
Is the Airtac GFC Combination Unit GFC300C08AF1WK the Right Set?
This code selects the 5 um element (W), the automatic drain (A), the embedded square MPa gauge (F1) and the reverse/check valve (K); the same set without the check valve is GFC300C08AF1W. With automatic or differential-pressure drain the regulator adjusts 0.15-0.9 MPa (20-130 psi); manual-drain variants in the family widen that to 0.05-0.9 MPa (7-130 psi). Size 300 gives a 1/4 in port; sizes 400 and 600 step up the port for heavier lines. PT is the standard thread, with G (BSPP) and NPT as catalogue thread options. 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 (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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08AF1WK FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and demand and we will confirm the sizing from the datasheet on request.
K means a reverse (check) valve is fitted, so flow through the set cannot run backwards. The identical set without the check valve is ordered as GFC300C08AF1W.
