AirTAC GFC300-10 Combination Unit (GFC30010AF1W)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AF1W) 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 PT3/8" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010AF1W)
This GFC300-10A-F1W is AirTAC's two-unit air preparation set - filter regulator plus lubricator - with the 5 um (W) filtration element for finer particle and water removal than the standard 40 um grade. It is the 300 size with PT 3/8 in. ports, an automatic drain on the filter bowl and the embedded square gauge reading in MPa. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) at up to 1.0 MPa (145 psi) inlet pressure; medium is compressed air, working temperature is -5 to 70 C (non-freezing), and both bowls on this 300 size are polycarbonate (PC).
This is a genuine AirTAC part. The W code is one catalogue option on the GFC two-unit set, which is otherwise available in 200, 300, 400 and 600 sizes with 1/8 to 1 in. ports, differential-pressure or manual drains, the 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, and PT (standard), G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010AF1W) Is Used
Test-rig and laboratory air supplies
Prepares air for instrumented test rigs and lab actuator stations, where the 5 um element gives finer filtration ahead of precision regulators, transducers and small-bore cylinders.
CNC machining-centre actuation
Feeds the tool-change cylinders, clamps and air blasts on a CNC machining centre, with the 5 um element, a set regulated pressure and lubrication for the actuators in one two-unit set.
Filling and capping machine actuation
Supplies the fill, cap and eject cylinders on bottling and filling lines, where the automatic drain and 5 um grade keep water and fine particulate out of the valve stack during continuous running.
Is the AirTAC GFC300-10 Combination Unit (GFC30010AF1W) the Right Set?
Pick the 5 um W element when downstream valves, cylinders or instruments need finer protection than the standard 40 um grade; 40 um remains the default on non-W GFC models. This is the 300 size with 3/8 in. PT ports - choose 200 for compact take-off points or 400/600 for larger ports and more flow. The automatic drain clears condensate without operator attention; manual and differential-pressure drains are the alternatives. The embedded square gauge reads MPa, with psi or bar scales and an external round gauge as options, and G (BSPP) or NPT threads can be ordered instead of PT.
Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010AF1W) FAQ
AirTAC publishes G-series flow as performance curves rather than one rated figure, so no single number is quoted here. Tell us the flow and working pressure your application needs and we will confirm sizing against the datasheet on request before you order.
The standard 40 um element suits general plant air. The 5 um W grade, fitted on this model, is for finer protection of control valves, precision cylinders and instruments. Both grades are catalogue options on the same GFC300-10A size, so the choice is purely about how clean the downstream air must be.
