Airtac GFC Combination Unit GFC300C10AF1WK
The AirTAC GFC Combination Unit GFC300C10AF1WK 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 GFC300C10AF1WK
The GFC300C10AF1WK is an AirTAC G-series two-unit air preparation set: a filter-regulator plus a separate lubricator in one package, fitted with a reverse (check) valve (K) so air cannot flow back through the set if the upstream supply drops. Air is filtered to the 5 um fine grade (W), downstream pressure is regulated over 0.15-0.9 MPa (20-130 psi) with the automatic drain (A) fitted, and oil mist is metered to the line. The 3/8 in PT port, PC bowls and embedded square gauge with MPa scale complete the configuration.
This is a genuine AirTAC part for compressed air only, rated to 1.0 MPa (145 psi) maximum working pressure and -5 to 70 C, non-freezing. The G series spans sizes 200 to 600 with ports from 1/8 to 1 in, in PT, G (BSPP) and NPT threads, with automatic, manual or differential-pressure drains, 40 or 5 um elements, gauge styles and scales, and the optional K reverse valve fitted here. AirTAC publishes flow as curves rather than a single rating, so we confirm 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-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 GFC300C10AF1WK Is Used
Pneumatic clamp circuits
The built-in check valve helps hold clamp pressure if the upstream supply dips, suiting fixture clamping on a machining or welding line where the clamps must stay engaged.
Paint spray booth
Filtered to 5 um, pressure-regulated and lubricated for spray guns, with reverse-flow protection on the supply drop to the booth.
Case-erector stations
Feeds packaging cylinders with filtered, regulated, lubricated air while the check valve stops backflow when upstream valves cycle on a carton-handling conveyor.
Is the Airtac GFC Combination Unit GFC300C10AF1WK the Right Set?
Size 300 with a 3/8 in PT port suits medium-flow branch circuits; step up to 400 or 600 for more flow or down to 200 for compact lines. The K code fits a reverse (check) valve - choose it where a falling upstream supply must not vent the downstream circuit. Drain here is automatic (A); manual (M) or differential-pressure (blank) are alternatives, with manual widening the regulating range down to 0.05 MPa. W selects the 5 um element over the standard 40 um, and F1 gives the embedded square gauge in MPa (round external gauges or N no-gauge are options). Thread is PT as standard; G (BSPP) and NPT are catalogue options. Flow is published as curves, not a single rating, so ask us to confirm sizing 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C10AF1WK FAQ
AirTAC publishes G-series capacity as flow curves rather than a single rated figure, so we cannot honestly quote one number. Share your working pressure and air demand and we will confirm the curve-based figures and full datasheet for the GFC300C10AF1WK on request.
K fits a reverse (check) valve so air cannot flow back through the set when the upstream supply drops, helping hold downstream pressure. The rest decodes as: 300 size, 10 = 3/8 in PT port, A = automatic drain, F1 = embedded square MPa gauge and W = 5 um element.
