AirTAC GFC300-08 Combination Unit (GFC30008ANK)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ANK) 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 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008ANK)
The GFC30008ANK is a size 300 two-piece set that filters, regulates and lubricates compressed air: a filter-regulator unit with automatic drain and the standard 40 um element, plus a matched lubricator. The trailing K adds a reverse-flow (check) valve; the plain GFC30008AN has none. Ports are PT1/4, there is no gauge fitted, maximum working pressure is 1.0 MPa (145 psi), the regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. Across the G series the two-unit sets are offered in sizes 200 to 600 with your choice of drain type, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scale, the check-valve option, and G (BSPP) or NPT threads alongside the PT standard. Flow is published as curves rather than a single rating, so we confirm sizing and 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.
Model Code: AirTAC GFC300-08 Combination Unit (GFC30008ANK)
| 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". |
| A | Drain: Automatic 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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 (GFC30008ANK) Is Used
Bottling line actuator drops
Feeding capped-bottle handling actuators where the check valve helps isolate the conditioned branch from backflow toward the supply side when adjacent circuits cycle.
Pneumatic riveting and fastening stations
Conditioning air for riveters and fastening tools at a fabrication bench, with regulated pressure, oil mist for the tool and automatic condensate drainage.
Fixture clamp circuits on machining cells
Supplying lubricated, regulated air to workholding clamps on a CNC cell where a steady downstream pressure matters from clamp to release.
Is the AirTAC GFC300-08 Combination Unit (GFC30008ANK) the Right Set?
Choose this code over the plain GFC30008AN when you want the reverse-flow check valve fitted at the factory. Otherwise the choices are the same: 300 size with 1/4 in ports for mid-range demand, automatic drain for unattended condensate removal, and the standard 40 um element with the 5 um W option for finer service. No gauge is included, but square or round gauges with MPa, psi or bar scales can be ordered. PT thread is standard, with G (BSPP) and NPT as catalogue alternatives. Because flow appears as curves rather than one rated figure, ask us to verify the size 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 (GFC30008ANK) FAQ
Yes - on request. AirTAC publishes G-series flow as curves rather than a single rated number, so share your line pressure and demand profile and we will confirm the correct size against the datasheet curves before you order.
The K specifies that a reverse-flow (check) valve is fitted to the set; the version without K has none. It is a factory-fitted option on the GFC two-unit sets, alongside drain type, filter grade and gauge choices.
