AirTAC GFC300-08 Combination Unit (GFC30008MF1WK)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MF1WK) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008MF1WK)
This GFC set pairs an AirTAC filter-regulator with a lubricator in one two-unit assembly, covering filtration, regulation and oil-mist lubrication of compressed air. The trailing K adds a reverse (check) valve to the circuit. The GFC300 size connects to 1/4 in PT piping, takes inlet pressure up to 1.0 MPa (145 psi), and uses manual-drain polycarbonate bowls that you empty by hand. The W element filters to 5 um, the embedded square gauge reads in MPa, and the manual-drain regulator covers 0.05-0.9 MPa (7-130 psi) of setting range.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in. PT is the standard thread, with G (BSPP) and NPT available as catalogue options. Service temperature is -5 to 70 C non-freezing at this size. Because flow is published as curves rather than a single rated figure, ask us to confirm capacity and the datasheet against 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 0.05 - 0.9 MPa (7 - 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 (GFC30008MF1WK)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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: GFR300-08 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 (GFC30008MF1WK) Is Used
Clamping fixture circuit
Feeds pneumatic clamps on a fixture where the check valve helps stop backflow through the prep set while the clamps stay under regulated, lubricated air.
Machine tool auxiliary circuit
Prepares air for tool-change and chip-clearing cylinders on a CNC cell, with 5 um filtration protecting the directional valves.
Air motor drive station
Supplies a rotary air motor on a workholding or turning station with regulated pressure and a continuous oil mist from the lubricator.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MF1WK) the Right Set?
Choose this code over GFC30008MF1W when the K (reverse/check valve) function is wanted in the set - for example where backflow through the unit is not acceptable. The 300 size and 1/4 in PT port suit mid-range circuits; 200 shrinks the step and 400/600 grow it. Manual drain fits attended areas; pick automatic or differential-pressure drain codes elsewhere. The 5 um element vs the standard 40 um element, and the MPa vs psi/bar gauge scale, are the other decodable choices. Flow appears as curves, not a single rating, so let us check your demand against the datasheet 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 0.05 - 0.9 MPa (7 - 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 (GFC30008MF1WK) FAQ
There is no single rated flow figure for this set - AirTAC publishes flow capacity as curves. Send us your air demand and inlet pressure and we will confirm the right size against the datasheet on request before you commit.
K means a reverse (check) valve is fitted in the set, so air will not flow backwards through it. The equivalent code without K omits the check valve. All other characters stay the same: 300 size, 1/4 in PT port, manual drain, 5 um element and MPa square gauge.
