AirTAC GFC300-08 Combination Unit (GFC30008C1WK)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008C1WK) 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 PT1/4" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008C1WK)
GFC30008C1WK is an AirTAC G-series two-unit air-treatment set: a filter-regulator and a lubricator working as a pair on 1/4 in PT connections, in the fully optioned variant. The W code fits the finer 5 um filter element instead of the standard 40 um, and the K code adds a reverse (check) valve. The regulator holds downstream pressure across the 0.15-0.9 MPa (20-130 psi) adjustment range, the drain is the default differential-pressure type, and the round external gauge reads on the MPa scale while the lubricator meters oil mist downstream. Bowls are polycarbonate at this size, maximum inlet pressure is 1.0 MPa (145 psi), and the working range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series comes in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options that include manual or automatic drains, gauge scales, and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet 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 GFC300-08 Combination Unit (GFC30008C1WK)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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). |
| C | Gauge shape: Round. 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. |

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: GFR300-08 filter regulator and GL300-08 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 GFC300-08 Combination Unit (GFC30008C1WK) Is Used
Textile machine jet and cylinder supply
Conditioning the air feeding yarn-threading jets and small cylinders on textile machinery, where the 5 um element protects the jet nozzles and the check valve isolates the circuit from supply dips.
Packaging machine clamp-and-seal station
Supplying the clamp and seal cylinders on a carton-sealing machine, with finely filtered, lubricated air and a check valve so reverse flow toward the supply is blocked.
Wire and cable cut-to-length lines
Feeding the hold-down and cutter actuators on a wire cut-to-length line, where clean regulated air and a local MPa gauge support consistent machine setup.
Is the AirTAC GFC300-08 Combination Unit (GFC30008C1WK) the Right Set?
Size the set by stepping through 200/300/400/600 with ports from 1/8 in to 1 in - this 300 variant is built around 1/4 in piping. Against the base GFC30008C1 you are selecting two options at once: the 5 um element (W) for finer filtration and the reverse/check valve (K) to block backflow through the set. The drain remains the default differential-pressure type, with automatic and manual codes available, and the gauge is the external round type on the MPa scale. PT is the standard thread; order G (BSPP) or NPT when the installation needs them.
Because G-series flow is published as curves rather than one rated number, let us confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008C1WK) FAQ
No single rated figure exists for this set - AirTAC publishes G-series flow as curves. Send us your application conditions and we will confirm the datasheet flow curve and the suitability of this 1/4 in set on request.
Yes. In this code the thread position is blank, which means PT is the standard; the trailing letter T gives NPT and G gives G (BSPP) as catalogue thread options. The 1/4 in port size itself stays the same.
