AirTAC GFC300-08 Combination Unit (GFC30008AC1K)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AC1K) 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 (GFC30008AC1K)
GFC30008AC1K is a two-piece AirTAC GFC air-preparation set for compressed air: a filter-regulator body plus a separate lubricator, so filtration, pressure regulation and oil-mist lubrication come from one order. This configuration is the size 300 frame with a 1/4 in PT port, an automatic drain on the filter bowl, the standard 40 um filter element, an external round pressure gauge reading in MPa, and a reverse (check) valve fitted. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C non-freezing, and the 300-size filter bowl is PC (polycarbonate).
This is a genuine AirTAC part. The GFC family runs in size 200, 300, 400 and 600 frames with ports from 1/8 in to 1 in, and options covering 40 um or 5 um elements, differential-pressure, automatic or manual drains, external round or square gauges in MPa, psi or bar scales, and a reverse/check valve. Flow for the G series is published as curves rather than a single rated figure, so we confirm the datasheet numbers 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 (GFC30008AC1K)
| 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. |
| (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. |
| (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. |

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 (GFC30008AC1K) Is Used
Palletiser gripper circuit
Supplies the gripper and pusher cylinders on a palletising line; the fitted check valve stops downstream air from pushing back through the set when the circuit exhausts or the supply dips.
Service-bench tool air
A point-of-use set for impact wrenches and air ratchets in a vehicle workshop, with automatic condensate draining, a visible MPa set pressure and a check valve in the supply path.
Press fixture clamping supply
Conditions air to the clamp cylinders on a fabrication press fixture; the regulator holds the set clamp pressure and the check valve guards the circuit against reverse flow.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AC1K) the Right Set?
The decodable choices: frame size (200/300/400/600) and port (1/8 to 1 in) stepped against the air your circuit uses; drain type - A here is automatic, against the default differential-pressure drain and M manual; element grade - 40 um standard or W for 5 um; gauge - C1 is the external round gauge in MPa, with psi (2), bar (3) and square-gauge options; and the K at the end, which fits the reverse/check valve this code carries. PT is the standard thread, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not a single rated figure, so ask us to 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 (GFC30008AC1K) FAQ
AirTAC publishes G-series flow capacity as curves rather than a single rated figure, so there is no single rated number to quote. Give us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
K means a reverse (check) valve is fitted in the set, so downstream air cannot flow back through the unit. The same GFC code without the K is supplied with no check valve.
