AirTAC GFC300-10 Combination Unit (GFC30010F1WK)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010F1WK) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010F1WK)
The AirTAC GFC two-unit set delivers filtration, regulation and lubrication from a filter-regulator plus a lubricator. GFC30010F1WK decodes as size 300, 3/8 in PT ports, the 5 um filter element (W), a reverse/check valve fitted (K), differential-pressure drain, standard regulation of 0.15-0.9 MPa (20-130 psi), an embedded square MPa gauge and a bracket. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing), with a polycarbonate bowl at this size.
This is a genuine AirTAC part for the US market. Across the G series you can order sizes 200, 300, 400 and 600, G(BSPP) or NPT threads, manual or automatic drains, the 40 um standard element, external round gauges and no-bracket variants on other codes. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures for your application 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.
Model Code: AirTAC GFC300-10 Combination Unit (GFC30010F1WK)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 (GFC30010F1WK) Is Used
Robot cell valve manifold
Conditioning air at the manifold feeding a welding-robot end-of-arm tooling circuit, with the 5 um element ahead of the pilot valves.
Machine shop drop line
A dedicated FRL drop serving mills and lathes in a machine shop, regulated to the pressure the fixture clamps are set up for.
Palletizer actuation supply
Feeding the grip and sweep cylinders of a palletizer cell, with oil mist maintained to the cylinders in continuous duty.
Is the AirTAC GFC300-10 Combination Unit (GFC30010F1WK) the Right Set?
Specify the K suffix when your circuit calls for a reverse/check valve to be fitted at the factory rather than added separately; dropping the K gives the identical set without it. The W grade (5 um) is the right pick for circuits with pilot valves or finishing equipment; the 40 um standard code suits general plant air. Drain, gauge scale and thread remain decodable choices: differential-pressure here with manual (M) or automatic (A) as codes, MPa/psi/bar gauge scales, and G(BSPP) or NPT in place of PT. Flow is published as curves, not a single rated number, so ask us to confirm sizing against your application before ordering.
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 (GFC30010F1WK) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no single number applies. Tell us your operating pressure and consumption and we will confirm the sizing and datasheet figures for the GFC30010F1WK on request.
K specifies that a reverse/check valve is fitted on this unit; the same set without the K carries none. All other decodes stay as shown: two-unit filter-regulator plus lubricator, 3/8 in PT ports, 5 um element, differential-pressure drain and a square MPa gauge.
